Findings

Among voters in the 2024 Cooperative Election Study (CES), seldom attenders voted more Democratic than frequent attenders by +9.5 (95% CI 6.6 to 12.4) points among white born-again Protestants and by +0.8 (95% CI −5.1 to 6.7) points among Black Protestants, an interval that includes zero. Seldom attenders go to religious services a few times a year or never, and frequent attenders go weekly or more. Among all voters the same gap, which Chapter 3.8, The god gap in America measures, was 27.7 (95% CI 26.0 to 29.4) points. The two groups sit at opposite ends of the vote. White born-again Protestants voted 14.5% Democratic in the two-party presidential vote and Black Protestants voted 83.1%. Both groups attend often. 57.8% of white born-again Protestant voters and 47.3% of Black Protestant voters attend weekly or more, against 26.7% of all voters. This chapter asks what the single all-voter gap combines.

Tradition and race are coded together. The CES has no denomination item, so white Protestants are split by whether they call themselves born-again or evangelical Christians. Those who do are white born-again Protestants and those who do not are white Protestants who are not born-again. Black, Hispanic and Asian or other-race Protestants are kept whole, and Catholics are split by race. The remaining groups are Jewish, Mormon, Muslim, Orthodox Christian, and Buddhist or Hindu voters, voters who gave another religion, and the unaffiliated, who are atheists, agnostics and people with no religion in particular. White means non-Hispanic white. The born-again rule stands in for denomination. A denominational scheme, RELTRAD [1], sorts Protestants into evangelical, mainline and Black Protestant traditions from the denomination they name, which the CES does not record. The rule ties the white born-again group to an answer that marks religious commitment, and the group of white Protestants who are not born-again is whoever is left. A gap in this chapter is the Democratic share among seldom attenders minus the share among frequent attenders, so a positive gap means that seldom attenders voted more Democratic.RELTRAD can be coded in the General Social Survey (GSS), and the 2024 American National Election Studies (ANES) have their own major-group summary, so results from those surveys use the terms evangelical and mainline, and the last section checks the CES rule against both. Shares use the survey weights, and the CES weight is the one defined for all five elections. Every interval is a 95% confidence interval from the Kish effective sample size [2], and a cell needs at least 30 respondents. The CES is an opt-in online panel, so its intervals cover sampling error and not how respondents were recruited. The sample is 188,145 CES respondents who reported voting for the Democratic or the Republican candidate in the five presidential elections from 2008 to 2024, 42,008 of them in 2024.

Chapter 3.8, The god gap in America measures the overall gap and compares the United States with other countries, Planned, The rise of the nones (planned) follows the unaffiliated, and Chapter 3.3, Hispanic, Black and Asian voters (planned) follows the vote of Black, Hispanic and Asian voters across traditions. This chapter takes the traditions one at a time and asks whether attendance relates to the vote in the same way inside each.

Two groups that attend often sit at opposite ends of the vote

Table 1 orders the groups by their Democratic share in 2024. White born-again Protestants were at 14.5% (95% CI 13.2% to 15.7%), white Catholics at 37.1% (95% CI 35.4% to 38.9%), white Protestants who are not born-again at 43.0% (95% CI 41.0% to 45.0%), Hispanic Catholics at 57.0% (95% CI 52.5% to 61.5%), the unaffiliated at 70.9% (95% CI 69.7% to 72.2%) and Black Protestants at 83.1% (95% CI 80.3% to 86.0%). Party identification gives the same order, from 13.7% Democratic among white born-again Protestants to 86.3% among Black Protestants (the third view). Pooled over the five elections the vote shares run from 18.1% (95% CI 17.6% to 18.7%) among white born-again Protestants to 91.4% (95% CI 90.4% to 92.3%) among Black Protestants (the second view).

Table 1. In 2024 the Democratic share of the two-party vote ran from 14.5% among white born-again Protestants to 83.1% among Black Protestants

Race separates voters inside each large Christian family. Among Catholics, Hispanic Catholics voted 19.9 (95% CI 15.0 to 24.7) points more Democratic than white Catholics, and the 2024 estimate for Black Catholics, 76.0% (95% CI 67.2% to 84.8%), rests on a small sample. Among Protestants, Hispanic Protestants voted 33.1% (95% CI 27.3% to 38.9%) Democratic, above white born-again Protestants and below Black Protestants. Hispanic voters divide by tradition. Hispanic Catholics voted 23.9 (95% CI 16.5 to 31.3) points more Democratic than Hispanic Protestants. Among white Protestants, those who are not born-again voted 28.5 (95% CI 26.1 to 30.8) points more Democratic than those who are.

Among the smaller traditions, Jewish voters were 68.0% (95% CI 64.0% to 72.1%) Democratic and Mormon voters 31.1% (95% CI 24.8% to 37.4%), both inside the range that white born-again Protestants and Black Protestants set. Muslim voters were 65.9% (95% CI 52.7% to 79.0%), and that interval is the widest in the figure.

Attendance does not order the groups. Table 2 plots the share of voters in each group who attend weekly or more against the Democratic share. Black Protestant voters attend weekly or more at 47.3% (95% CI 43.6% to 51.1%) and say religion is very important in their life at 72.3%, and 70.6% call themselves born-again or evangelical, the answer that defines white born-again Protestants here. For white born-again Protestants the first two shares are 57.8% (95% CI 56.0% to 59.5%) and 79.8%. Among all voters they are 26.7% and 39.0%. Hispanic Protestant voters (55.6% weekly) and Mormon voters (67.7%) also attend often and voted 33.1% and 31.1% Democratic, while the unaffiliated, of whom 2.5% attend weekly, voted 70.9%. The groups with the highest Democratic shares include one with a high attendance rate and one with a low one.

Table 2. White born-again and Black Protestant voters attend weekly or more at 57.8% and 47.3%, against 26.7% of all voters, and voted 14.5% and 83.1% Democratic

Two groups with weekly attendance of 57.8% and 47.3%, against 26.7% among all voters, voted 68.6 (95% CI 65.6 to 71.7) points apart. The data cannot say why. Accounts of the Black church describe an institution of community and political life as well as of worship [3], but the survey items here measure attendance, importance and identification and not what congregations do.

The five largest Christian groups moved Republican by different amounts

Table 3 compares each later election with 2008. Over the full period the Democratic share changed by −13.2 (95% CI −19.5 to −6.9) points among Hispanic Catholics, −10.3 (95% CI −14.1 to −6.5) among Black Protestants, −7.9 (95% CI −10.7 to −5.1) among white Protestants who are not born-again, −6.5 (95% CI −8.9 to −4.0) among white Catholics and −6.2 (95% CI −8.1 to −4.4) among white born-again Protestants. Each of those intervals lies below zero. The five groups and the unaffiliated, who changed by −5.6 (95% CI −7.6 to −3.7) points, kept the same order in 2008 and 2024, from Black Protestants at 93.4% and 83.1% to white born-again Protestants at 20.7% and 14.5%.

Table 3. From 2008 to 2024 the Democratic share changed by −13.2 points among Hispanic Catholics and −10.3 among Black Protestants, against −6.2 among white born-again Protestants and −6.5 among white Catholics

The two largest falls are those of Hispanic Catholics and Black Protestants, and the differences between the changes can be tested. The change among Hispanic Catholics differs from the change among white born-again Protestants by −7.0 (95% CI −13.5 to −0.4) points and from the change among the unaffiliated by −7.6 (95% CI −14.2 to −1.0). The change among Black Protestants differs from the change among the unaffiliated by −4.7 (95% CI −8.9 to −0.4). Hispanic Catholics differ from white Catholics by −6.7 (95% CI −13.5 to 0.0), an interval that reaches zero, and every other difference among the six changes has an interval that includes zero. The groups that moved most are therefore separable from some of the others and not from all of them.

The order does not hold for every group. Muslim voters, Black Catholic voters and Buddhist or Hindu voters were among the most Democratic in 2008 and changed by −30.1 (95% CI −44.8 to −15.4), −18.5 (95% CI −28.7 to −8.2) and −19.5 (95% CI −28.1 to −10.9) points, so the order of all the groups differs between 2008 and 2024. Hispanic Protestants, Jewish voters and Mormon voters show no change that the sample can separate from zero, at −3.3 (95% CI −13.0 to 6.4), −3.3 (95% CI −9.2 to 2.5) and +6.5 (95% CI −1.2 to 14.2) points. The last is the only point estimate that rose by more than a few points. Chapter 3.3, Hispanic, Black and Asian voters (planned) follows Black and Hispanic voters as a whole, and the figure here describes the same voters split by tradition.

Attendance relates to the vote in different directions inside each group

Table 4 splits each group by attendance. One sign comes from the CES coding and is not reproduced in the other surveys: the gap among white Protestants who are not born-again, taken up below and in the last section. Pooled over the five elections, seldom attenders voted more Democratic than frequent attenders by +10.1 (95% CI 8.7 to 11.4) points among white born-again Protestants, +13.7 (95% CI 12.2 to 15.3) among white Catholics, +11.9 (95% CI 7.5 to 16.3) among Hispanic Catholics and +13.8 (95% CI 7.5 to 20.0) among Hispanic Protestants. The white Catholic gap exceeds the white born-again gap by 3.6 (95% CI 1.6 to 5.7) points, and the two Hispanic intervals are wide enough to include both. In 2024 alone the four gaps were +9.5 (95% CI 6.6 to 12.4), +12.0 (95% CI 8.1 to 15.9), +15.3 (95% CI 4.9 to 25.7) and +10.6 (95% CI −2.0 to 23.2).

Table 4. Inside tradition-by-race groups the vote differs by attendance in different directions: seldom minus frequent attenders in the Democratic share was +13.7 points among white Catholics, +10.1 among white born-again Protestants, +1.9 among Black Protestants and −5.4 among white Protestants who are not born-again, a sign that the GSS and ANES do not reproduce

Among Black Protestants the pooled gap is small, +1.9 (95% CI 0.0 to 3.8) points, with frequent attenders at 90.7% and seldom attenders at 92.6% Democratic, and for party identification it is +2.6 (95% CI 1.0 to 4.2) points. The vote interval lies below the intervals of the four groups above, so Black Protestants who attend often and seldom voted within a few points of one another. The same two attendance groups among white born-again Protestants voted +10.1 points apart. In 2024 alone the Black Protestant gap was +0.8 (95% CI −5.1 to 6.7) points. In 2008 the gaps were +4.9 (95% CI −0.1 to 9.9) for Black Protestants, +15.1 (95% CI 11.5 to 18.6) for white born-again Protestants and −4.4 (95% CI −9.4 to 0.6) for white Protestants who are not born-again, the same order as in the pooled estimates.

Among white Protestants who are not born-again the direction reverses in the CES, and this is the sign that the GSS and the ANES do not reproduce. The GSS gives +2.8 (95% CI −3.8 to 9.4) points for the RELTRAD mainline group and +5.7 (95% CI −0.5 to 12.0) under the born-again rule, and the ANES gives +11.6 (95% CI −3.4 to 26.6) (the last section). In the CES, frequent attenders voted 50.5% Democratic and seldom attenders 45.1%, a gap of −5.4 (95% CI −7.5 to −3.4) points, and the point estimate is below zero in each of the five elections. The gap was −8.1 (95% CI −12.2 to −4.0) points in 2020 and −4.1 (95% CI −9.0 to 0.8) in 2024. Party identification gives the same signs in the CES, +11.2 (95% CI 9.9 to 12.5) among white born-again Protestants, +2.6 (95% CI 1.0 to 4.2) among Black Protestants and −3.7 (95% CI −5.8 to −1.7) among white Protestants who are not born-again (the last view).

Jewish voters, Mormon voters and the unaffiliated have positive gaps, +23.8 (95% CI 17.9 to 29.8), +17.5 (95% CI 11.1 to 23.9) and +18.1 (95% CI 14.1 to 22.1) points, with intervals wider than those of the larger groups because one of their two attendance cells is small. The Jewish gap exceeds the white born-again gap by 13.7 (95% CI 7.6 to 19.8) points. A positive gap means that seldom attenders voted more Democratic, and the sign does not say that attendance moves the vote.

The pooled gap is a sum of different gaps and different mixes

The pooled gap can be written as two parts. The within-group part is each group's own seldom-minus-frequent gap, weighted by the group's average share of the two attendance groups. The mix part is the difference between a group's share of seldom attenders and its share of frequent attenders, valued at the group's average Democratic share relative to all voters. The two parts add to the pooled gap exactly, and the split is an accounting of the gap and not a causal one. In 2024 the pooled gap of 27.7 (95% CI 26.0 to 29.4) points, the gap of Chapter 3.8, The god gap in America restricted to voters with a group and an attendance answer, divides into 14.6 (95% CI 11.8 to 17.4) points within groups and 13.1 (95% CI 10.6 to 15.5) points from the mix (Table 5). Pooled over the five elections the gap is 24.4 (95% CI 23.7 to 25.1) points, of which 11.4 (95% CI 10.3 to 12.4) is within groups and 13.1 (95% CI 12.2 to 13.9) is the mix. Each part is at least 8.0 points in every election, and the mix part is the larger in 3 elections and the within-group part in the others.

Table 5. Of the 27.7 point gap between seldom and frequent attenders in the 2024 vote, 14.6 points is a gap inside tradition-by-race groups and 13.1 points reflects which groups the two attendance levels contain

Table 6 assigns the parts to groups. White born-again Protestants are 39.0% (95% CI 37.5% to 40.6%) of the voters who attend weekly or more and 9.1% (95% CI 8.6% to 9.7%) of those who attend seldom. They are less Democratic than other voters, so their concentration among weekly attenders adds 10.2 (95% CI 9.5 to 10.9) points to the mix part. Black Protestants are 8.4% (95% CI 7.5% to 9.3%) of weekly attenders and 3.0% (95% CI 2.7% to 3.3%) of seldom attenders and are more Democratic than the average voter, so their contribution to the mix part is −1.8 (95% CI −2.2 to −1.5) points, below zero. White Catholics add 1.5 (95% CI 1.0 to 2.0) points through their own gap and white born-again Protestants 2.3 (95% CI 1.6 to 3.0). Pooled over the five elections, white born-again Protestants contribute 9.2 (95% CI 9.0 to 9.5) points through the mix and the unaffiliated 3.9 (95% CI 3.1 to 4.8) points through their own gap, the largest part of each kind.

Table 6. White born-again Protestants contribute 10.2 points to the mix part of the 2024 gap and Black Protestants −1.8 points, while the unaffiliated contribute 7.2 points to the within-group part

The unaffiliated need a caution. They are 44.8% (95% CI 43.9% to 45.7%) of seldom attenders and 3.0% (95% CI 2.3% to 3.6%) of weekly attenders, and they contribute 3.1 (95% CI 1.0 to 5.3) points through the mix and 7.2 (95% CI 4.7 to 9.7) points through their own gap. The second is 49.4% (95% CI 38.9% to 59.8%) of the 2024 within-group part, and without the unaffiliated that part is 7.4 (95% CI 6.0 to 8.8) points. It rests on a small weekly cell, with an effective sample of 77 respondents in 2024 against 134, 212 and 208 in 2012, 2016 and 2020. The unaffiliated gap was +0.4 (95% CI −11.5 to 12.3) points in 2008 on an effective weekly sample of 51, then +20.2 (95% CI 11.7 to 28.8), +15.7 (95% CI 8.9 to 22.6) and +14.3 (95% CI 7.5 to 21.0) points, and +30.1 (95% CI 19.0 to 41.3) in 2024. The 2024 estimate is the largest of the five, and its interval overlaps those of 2012, 2016 and 2020.

The pooled gap therefore contains two kinds of difference. One is the difference in vote between seldom and frequent attenders inside a tradition and race, which is small among Black Protestants and below zero in the CES among white Protestants who are not born-again, a sign that other surveys do not reproduce. The other is a difference in who the two attendance groups are. Because Black Protestants are a larger share of frequent attenders than of seldom attenders, they hold the pooled gap below what the other groups alone would give. The born-again rule also builds part of the white born-again contribution into the coding, because the group is defined by an answer that marks religious commitment.

In the GSS white RELTRAD evangelical Protestants leaned Democratic in the 1970s

The CES begins in 2008. The GSS asks Protestants which denomination they belong to, which allows RELTRAD from 1972 to 2022 (68,896 respondents placed; the 2024 GSS has no detailed denomination). This chapter codes it from the denomination and open-ended answers with the published syntax of the scheme, as the methods note describes. Table 7 follows the Democratic share of party identifiers in five windows of survey years. Among white RELTRAD evangelical Protestants it fell from 61.0% (95% CI 59.0% to 63.0%) in 1972 to 1984 to 43.8% in 1985 to 1996, 35.3% in 1998 to 2008 and 30.6% (95% CI 28.1% to 33.1%) in 2010 to 2018. Black Protestants stayed between 88.5% and 91.1% in every window, and white RELTRAD mainline Protestants between 40.9% and 45.4%. Catholics, of any race, fell from 72.4% (95% CI 70.7% to 74.1%) to 56.9% (95% CI 55.1% to 58.8%) and were at 58.3% (95% CI 55.7% to 60.9%) in 2010 to 2018. The GSS race item counts respondents of Hispanic origin who say white as white. 7.7% of white RELTRAD evangelical respondents in 2010 to 2018 are of Hispanic origin, and the non-Hispanic Democratic share is 28.8% (95% CI 26.3% to 31.4%) against 30.6%.

Table 7. In the GSS the Democratic share of party identifiers among white RELTRAD evangelical Protestants fell from 61.0% in 1972 to 1984 to 30.6% in 2010 to 2018, while Black Protestants stayed near 91.1%

Attendance separated white RELTRAD evangelical Protestants before the group moved. In 1972 to 1984 frequent attenders were 55.0% (95% CI 52.0% to 58.1%) Democratic and seldom attenders 67.4% (95% CI 64.3% to 70.5%), a gap of +12.4 (95% CI 8.0 to 16.8) points, and the gap was +17.1 (95% CI 11.4 to 22.7) in 2010 to 2018. Its interval lies above zero in every window except the last, where it includes zero (+4.7 (95% CI −3.5 to 12.9)). The Black Protestant gap has an interval that includes zero in all five windows. The white RELTRAD mainline gap was +12.3 (95% CI 8.3 to 16.4) points in 1972 to 1984 and −3.5 (95% CI −11.8 to 4.8) in 2010 to 2018. Frequent mainline attenders were less Democratic than seldom attenders early, and by the 2010s the gap is within sampling error of zero. The 2021 to 2022 window, at +10.1 (95% CI −0.9 to 21.2), does not continue that path.

The last window includes web interviews and its estimates differ with the mode. White RELTRAD evangelical Protestants were 16.0% (95% CI 12.4% to 19.6%) Democratic across 2021 to 2022. In 2022, in-person respondents gave 9.2% (95% CI 2.2% to 16.3%) and web respondents 12.4% (95% CI 4.3% to 20.5%), and the 2021 survey, 87.8% of it on the web, gave 21.3% (95% CI 16.5% to 26.1%). RELTRAD also leaves 7.6% of respondents in that window unplaced. 5.4% of respondents are Protestants with no denomination who attend less than monthly and 1.6% are respondents who say only Christian or interdenominational, a gap in the syntax that [4] describe. Counting every white respondent that RELTRAD cannot place as evangelical gives 23.5% (95% CI 20.0% to 27.0%) Democratic, and counting only those who say Christian or interdenominational gives 18.0% (95% CI 14.4% to 21.6%). Even the larger estimate lies below the estimate for 2010 to 2018.

The ANES cumulative file measures the presidential vote and not party identification, and its born-again item, asked in every presidential-year study from 1980 to 2020 except 2004, allows the CES rule (the second view of Table 7). White born-again Protestants voted 30.1% (95% CI 26.8% to 33.5%) Democratic in 1980 to 1988 and 19.1% (95% CI 16.5% to 21.8%) in 2016 to 2020. By party identification the GSS puts white RELTRAD evangelical Protestants at 61.0% in the first window and the ANES puts white born-again Protestants at 44.0% (95% CI 40.8% to 47.1%). The gap between the GSS party share and the ANES vote share therefore has two sources, the coding of the group and the difference between identification and vote. White Protestants who are not born-again voted 30.9% (95% CI 27.8% to 33.9%) Democratic in 1980 to 1988 and 47.0% (95% CI 43.6% to 50.4%) in 2016 to 2020, a rise whose intervals do not overlap, while their party identification is flat at 42.5% and 42.0%, as the GSS series is. Black Protestants were at 91.7% and 93.1% and white Catholics at 42.9% and 42.5%. The 2012 and 2016 ANES studies add web samples and the 2020 study was collected online, by telephone and by video, so the last windows mix interview modes.

The sign for white Protestants who are not born-again depends on survey and coding

The CES rule puts a white Protestant in the born-again group when the respondent calls themselves born-again or evangelical. In the GSS from 2006 to 2018, the two codings agree for 61.3% of white Protestants with a born-again answer and a party identification, counting respondents RELTRAD cannot place as disagreeing and leaving out pure independents. They agree for 70.7% of those RELTRAD places in the evangelical or mainline tradition. Among white Protestants RELTRAD places, with no condition on party identification, 39.0% of those who are not born-again are RELTRAD evangelical and 22.3% of those who are born-again are RELTRAD mainline, so the CES groups are not the denominational ones. Table 8 shows what that does. The first tab compares 2024 levels in the CES and the ANES with the born-again rule applied in both. The ANES puts white Protestants who are not born-again at 56.1% (95% CI 49.9% to 62.3%) Democratic and the CES at 43.0% (95% CI 41.0% to 45.0%), a difference of +13.2 (95% CI 6.7 to 19.7) points, and the major-group summary of the ANES gives 57.6% (95% CI 51.0% to 64.1%) for its mainline category. The ANES national Democratic share, 54.4% (95% CI 52.2% to 56.7%), is above the CES share, 49.0% (95% CI 48.2% to 49.7%), and the certified count, 49.2%, so part of the difference belongs to the survey. The ANES also places each of six groups above the CES and orders them the same way.

Table 8. The ANES and the CES differ by +13.2 points for white Protestants who are not born-again in 2024, and only the CES puts their attendance gap below zero

The second tab gives the attendance gap for the evangelical and the mainline group of white Protestants under six combinations of survey and coding. The gap in the evangelical group has a positive point estimate in every row, +10.1 (95% CI 8.7 to 11.4) points in the CES vote, +19.3 (95% CI 14.6 to 24.1) in the GSS under RELTRAD and +11.9 (95% CI 0.1 to 23.8) in the ANES under its own summary. Its interval lies above zero in every row except the ANES born-again row. The sizes differ across surveys. The gap in the mainline group is below zero in the CES, −5.4 (95% CI −7.5 to −3.4) points for the vote and −3.7 (95% CI −5.8 to −1.7) for party identification, and its interval includes zero under the denominational codings of the GSS, +2.8 (95% CI −3.8 to 9.4), and the ANES, +11.6 (95% CI −3.4 to 26.6). Applying the CES born-again rule to the GSS gives +5.7 (95% CI −0.5 to 12.0) and to the ANES +6.2 (95% CI −7.9 to 20.3), so the rule alone does not reproduce the CES sign. The data do not say whether the CES result comes from its sample, from the mode of interview or from the rule, and the gap among white Protestants who are not born-again is the least settled estimate in this chapter.

What these data cannot show

Each survey interviews a different sample, so the gaps compare groups and say nothing about any voter changing. Religious behavior and identity respond to politics as well as the reverse. Panel studies find that partisan identity shapes whether people identify with a religion and how often they attend [5] [6]. A gap between seldom and frequent attenders, or a difference between traditions, can therefore reflect people moving between groups, and the decomposition splits an observed gap into parts without saying what would happen if the mix of attenders changed.

Tradition in the CES is a proxy for denomination. The CES cannot separate Baptist, Methodist, Lutheran and non-denominational respondents, cannot place Black Protestants by denomination, and cannot tell Pentecostal from other Hispanic Protestants. The GSS codes tradition by denomination but stops in 2022, records Hispanic origin only from 2000, and leaves 5.3% of respondents in 2010 to 2018 unplaced. The ANES 2024 rows of the coding check have wider intervals than the CES rows, and the ANES sample is too small to give a Hispanic Protestant estimate at all.

The levels depend on the survey and the weight. The CES estimates use the cumulative-file weight because it is the one CES weight defined for all five elections; the validated-vote weight exists only for 2018 to 2024. In 2024 it gives 34.1% (95% CI 32.4% to 35.8%) for white Catholics against 37.1%, 13.2% (95% CI 11.9% to 14.4%) for white born-again Protestants against 14.5% and 59.6% (95% CI 53.9% to 65.2%) for Hispanic Catholics against 57.0%. The CES national Democratic share is 49.0% with the cumulative-file weight and 49.1% with the validated-vote weight, against a certified 49.2%. Agreement at the national level does not show that a survey is accurate inside a tradition and race. The ANES group levels exceed the CES levels by the most for white Protestants who are not born-again and Hispanic Catholics, and by more than the two national shares differ. Small groups carry intervals as wide as the Muslim estimate, and the figures draw those intervals; the only cells removed are those under the floor.

The sample is voters who reported a Democratic or Republican vote, so nonvoters, third-party voters and respondents who did not answer are outside it. The chapter has no measure of belief, congregation, region or age, and nothing in it identifies why Black Protestants and white born-again Protestants vote as they do. The growth of the unaffiliated and their subtypes belong to Planned, The rise of the nones (planned), and the link between attendance and moral attitudes to Planned, Two moralities (planned).

Note: White born-again Protestants and white Protestants who are not born-again are the white Protestants who do and do not call themselves born-again or evangelical, because the CES file has no denomination; the last figure compares this coding with denominational codings. Black, Hispanic and Asian or other-race Protestants and the Catholic groups are not split further.

Note: The interval width is in the data table. A cell is drawn only when it has at least 30 respondents and an effective sample of at least 30. Intervals are 95% intervals from the Kish effective sample size and treat the weighted sample as a simple random sample. The CES is an opt-in online panel, so they cover sampling error and not how respondents were recruited.

Table 4. Inside tradition-by-race groups the vote differs by attendance in different directions: seldom minus frequent attenders in the Democratic share was +13.7 points among white Catholics, +10.1 among white born-again Protestants, +1.9 among Black Protestants and −5.4 among white Protestants who are not born-again, a sign that the GSS and ANES do not reproduce

Note: The pooled gap here covers voters with a tradition-by-race group and an attendance answer in the frequent or seldom group, so it can differ by a few tenths of a point from the all-voter gap of the god-gap chapter. The within part weights each group's own gap by its average share of the two attendance groups, and the mix part prices the difference in the groups' shares at each group's average Democratic share; the two parts add to the pooled gap exactly.

Note: Standard errors come from 1,000 seeded bootstrap resamples of respondents; the interval is a normal 95% interval around the estimate. The decomposition is an accounting of the gap and not a causal split.

Note: The unaffiliated contribute 7.2 of the 14.6 points of the 2024 within-group part, and without them that part is 7.4 points. Their weekly cell has an effective sample of 77 respondents in 2024 against 134, 212 and 208 in 2012, 2016 and 2020, and their gap of +30.1 points in 2024 compares with +20.2, +15.7 and +14.3 in those elections.

Note: The unaffiliated within-group contribution rests on a small number of weekly attenders: the frequent cell has an effective sample of 77 in 2024. Intervals are 95% intervals from the Kish effective sample size and treat the weighted sample as a simple random sample.

Note: A group enters when it has at least 30 voters with a frequent or seldom attendance answer in the sample.

Views: GSS party identification, 1972 to 2022 (source = GSS); ANES presidential vote, 1980 to 2020 (source = ANES).

Note: GSS view: tradition follows RELTRAD (Steensland and others 2000) from the GSS denomination items; the 2024 GSS has no detailed denomination, so the series ends in 2022. White evangelical and white mainline Protestants are RELTRAD evangelical and mainline respondents whose GSS race is white, which includes white respondents of Hispanic origin. Catholics are all Catholics, since the GSS records Hispanic origin only from 2000.

Note: Frequent attenders attend nearly every week or more; seldom attenders a few times a year or never. The window 2021 to 2022 mixes web and in-person interviews: 87.8% of 2021 respondents were interviewed on the web. Respondents that RELTRAD cannot place are left out, 7.6% of respondents in 2021 to 2022. A cell is drawn only when it has at least 30 respondents and an effective sample of at least 30. Intervals are 95% intervals from the Kish effective sample size and treat the weighted sample as a simple random sample.

Note: ANES view: reported two-party presidential vote, with the born-again rule of the CES. The born-again item is asked in every presidential-year study from 1980 to 2020 except 2004, and a respondent with no answer is in neither white Protestant group. The 2012 and 2016 studies add web samples and the 2020 study was collected online, by telephone and by video, so the last windows mix interview modes with the in-person studies of earlier years; there are no mode weights for 2020. The ANES weight is 1 for every respondent from 1980 to 1990. The 2024 religion codes of the cumulative file are unusable, so the series ends in 2020.

Table 8. The ANES and the CES differ by +13.2 points for white Protestants who are not born-again in 2024, and only the CES puts their attendance gap below zero

In 2024 the ANES places each of six groups above the CES, most for white Protestants who are not born-again and Hispanic Catholics, and the two surveys order the groups identically

Table 8.2. Attendance gap by coding

The attendance gap among born-again or evangelical white Protestants has a positive point estimate under every coding and survey, and among not born-again or mainline white Protestants it is negative only in the CES

Note: The CES rule puts white Protestants who call themselves born-again or evangelical in the evangelical group and the others in the mainline group. The GSS RELTRAD rows use denomination, the ANES summary rows use the ANES major-group religion summary (V241445x), and the born-again rows in the GSS and the ANES apply the CES rule to those surveys. This chapter has not checked the ANES summary against RELTRAD. In the GSS, 61.3% of white Protestants with a born-again answer and a party identification fall in the same group under RELTRAD and the born-again rule, counting respondents RELTRAD cannot place as disagreeing and leaving out pure independents; among those RELTRAD places in the evangelical or mainline tradition the share is 70.7%.

Note: Among white Protestants whom RELTRAD places in the evangelical or mainline tradition, 39.0% of those who are not born-again are RELTRAD evangelical and 22.3% of those who are born-again are RELTRAD mainline.

Note: GSS rows cover the surveys of 2006 to 2018, in all interview modes those surveys used, which include some telephone interviews; the CES rows cover the five presidential elections, and the ANES rows 2024, which mixed in-person, web and mail-return samples under one post-election weight. Frequent in the GSS is nearly weekly or more and in the ANES weekly or almost weekly, one answer wider than the CES. A cell is drawn only when it has at least 30 respondents and an effective sample of at least 30. Intervals are 95% intervals from the Kish effective sample size and treat the weighted sample as a simple random sample.

Definitions

Percentage point: The unit for the difference between two percentages. A change from one share to another is stated in points, not in percent, so that absolute and relative change are not confused.
Survey weights: Numbers that scale each respondent so the sample matches the population on known traits such as age, race, education and region. A weighted average counts a respondent with a large weight for more than one with a small weight.
Confidence interval: A range around an estimate that would contain the true value in 95% of repeated samples if the sampling model held. The book reports 95% intervals unless it says otherwise.
Effective sample size: The number of equally weighted respondents that would give the same precision as the weighted sample. It is smaller than the raw count when the weights vary a lot, and it sets how wide the confidence interval is.

Methods

Sample. Cooperative Election Study (CES) cumulative file, presidential years 2008, 2012, 2016, 2020 and 2024: 188,145 respondents who reported voting for the Democratic or the Republican presidential candidate (third-party and other votes are excluded), and 227,049 respondents who identify with or lean toward a party. Outcomes are the Democratic share of the reported two-party presidential vote and the Democratic share of Democratic and Republican identifiers (CES pid7 1 to 3 against 5 to 7, leaners with their party).

Tradition and race in the CES. The cumulative file has religion (1 Protestant, 2 Catholic, 3 Mormon, 4 Orthodox, 5 Jewish, 6 Muslim, 7 Buddhist, 8 Hindu, 9 atheist, 10 agnostic, 11 nothing in particular, 12 something else), race (race5: white non-Hispanic, Black, Hispanic, Asian, other) and the born-again or evangelical self-description (relig_bornagain). White Protestants who say yes are white born-again Protestants and those who say no are white Protestants who are not born-again. Black, Hispanic and Asian or other-race Protestants and Black, Hispanic, white and Asian or other-race Catholics are separate groups. Codes 9 to 11 are the unaffiliated. There is no denomination item, so the born-again rule is a proxy for the evangelical and mainline traditions, and the chapter calls the CES groups by the rule and keeps the names evangelical and mainline for the denominational codings of the GSS and the ANES. Attendance is the six-point item church_attend_6pt: frequent is once a week or more than once a week (codes 5 and 6) and seldom is never, seldom or a few times a year (codes 1 to 3); monthly attenders (code 4) are in neither group.

Weights and pooling. CES estimates use weight_cumulative, which sums to the same total in every year over all respondents, so pooled estimates over the five elections count each election by its weighted voters. It is used instead of the validated-vote weight vvweight because it is the only CES weight defined for all five elections (vvweight exists for 2018 to 2024, and it also requires a validated turnout record); the text gives the 2024 shares of three groups and of all voters under vvweight. Pooled GSS windows use weight_use rescaled to average one within each survey year. ANES 2024 estimates use the post-election weight V240107b.

Estimators and intervals. A share is a weighted mean of a 0/1 variable, and a gap or a change is the difference of two independent shares with the standard errors combined in quadrature; a difference between two changes combines the four standard errors, and a difference between two gaps combines the two. Every interval is a 95% interval from the Kish effective sample size with a normal approximation. The CES is an opt-in online panel, so its intervals are model based and cover sampling error and not the recruitment of respondents, and none of the intervals follows the clustering of a sampling design. Suppression: a cell is published only with at least 30 respondents and an effective sample of at least 30. The figures draw the interval of every published cell, and the tables give its width.

Decomposition. With p_gS and p_gF the shares of group g among seldom and frequent attenders and m_gS and m_gF its Democratic percentages, the seldom-minus-frequent gap equals the sum over groups of pbar_g (m_gS minus m_gF) plus the sum over groups of (p_gS minus p_gF) mbar_g, where pbar_g and mbar_g are averages of the two cells. The first sum is the within-group part and the second the mix part; subtracting the overall mean from mbar_g changes no total and gives each group's contribution. Standard errors are the standard deviation over 1,000 resamples of respondents with replacement (seed 12345), and the interval is a normal 95% interval around the estimate. The within-group part without the unaffiliated and the unaffiliated share of the within-group part use the same resamples.

GSS RELTRAD. Tradition follows Steensland and others (2000), coded from the posted syntax of Jerry Park for the Association of Religion Data Archives (6 August 2018), which implements the scheme: relig (religious preference), the detailed denomination denom (the file's denom_7222, asked 1972 to 2022; the 2024 GSS has only a seven-group denom and no other-denomination code, so 2024 cannot be coded), the open-ended other-denomination code other, race and attend. The variable fund is not used by the syntax. Black Protestant: the National Baptist Conventions, the African Methodist Episcopal churches, a list of Black sectarian other codes, and Black respondents in other Baptist, American Baptist, Southern Baptist, Baptist-do-not-know-which, other Methodist and Methodist-do-not-know-which groups. Evangelical: a list of other codes, the American Baptist Association, Southern Baptist and other Baptist groups, white Baptist-do-not-know-which, white other Methodist, Missouri, Wisconsin and other Lutheran synods, the Presbyterian Church in America, and Protestants with no denomination who attend at least monthly. Mainline: a list of other codes, United Methodist, white Methodist-do-not-know-which, American Baptist Churches USA (white), the other Lutheran and Presbyterian groups and Episcopalians. Catholic, Jewish, other faith and unaffiliated follow relig and a list of other codes; Jacobite Apostolics are coded Orthodox. Respondents the syntax cannot place are left out of every tradition: Protestants with no denomination who attend less than monthly, respondents who answer only Christian or interdenominational, and other codes 161 and 185. The syntax's own comment says codes 161 and 185 are dropped but its order of statements leaves them classified; this chapter drops them. 68,896 respondents are placed. Stetzer and Burge (2016) describe the omission of generic Christian and interdenominational answers from the evangelical tradition. This chapter keeps the syntax as written and bounds the effect for 2021 to 2022: the text gives the white evangelical Democratic share when every white respondent RELTRAD cannot place (Protestants with no denomination who attend less than monthly, and those who say only Christian or interdenominational) is counted as evangelical, and when only those who say Christian or interdenominational are. Tradition by race in the GSS: white evangelical and white mainline Protestants are RELTRAD evangelical and mainline respondents whose race is white (race 1), which includes white respondents of Hispanic origin (Hispanic origin is recorded from 2000, and the text gives the non-Hispanic share for 2010 to 2018); Black Protestants are the RELTRAD Black Protestant category; Catholics are all Catholics; Black respondents that RELTRAD places in the evangelical or mainline traditions and respondents of other races in those two traditions belong to no group. Windows pool survey years (1972 to 1984, 1985 to 1996, 1998 to 2008, 2010 to 2018, 2021 to 2022). Party is partyid 0 to 2 against 4 to 6, and attendance groups are frequent (attend 6 to 8, nearly every week or more) and seldom (attend 0 to 3). The born-again rule in the GSS uses reborn (1 yes, 2 no) among white respondents who say Protestant, 2006 to 2018. The agreement between RELTRAD and the born-again rule is computed on white Protestants with a born-again answer and a party identification (pure independents out; respondents RELTRAD cannot place count as disagreeing) and, separately, among those RELTRAD places in the evangelical or mainline tradition; the cross-check of each group by the other rule uses white Protestants with a born-again answer whom RELTRAD places, with no condition on party identification.

ANES 2024 Time Series. Religion is the ANES major-group summary V241445x (mainline, evangelical, Black Protestant, undifferentiated Protestant, Roman Catholic, other Christian, Jewish, other religion, not religious); this chapter has not checked its rules against RELTRAD. Race is V241501x. In the coding check the ANES evangelical and mainline groups are white respondents in those two ANES categories. For the comparison of levels with the CES, white Protestants are split by the born-again rule (V241442) among white respondents in the four ANES Protestant categories, as in the CES; Black and Hispanic Protestants are Black and Hispanic respondents in any Protestant category, and Catholics are split by race. Attendance is V241440 (frequent: every week or almost every week; seldom: a few times a year or never, with V241439 = no counted as never). A reported voter has V242095x = voted and V242096x = Harris or Trump; 3,928 respondents meet this. The 2024 study mixes face-to-face, web and mail-return samples under one weight and is not split by mode.

ANES Cumulative Data File. Respondents in the presidential-year studies of 1980 to 2020 (the 2024 religion codes of the cumulative file are unusable); the midterm studies of the file carry no presidential vote. Groups follow the CES rule: white non-Hispanic Protestants (religion, race_4cat) who say they are born-again (born_again, asked in every presidential-year study from 1980 to 2020 except 2004) and who do not, Black non-Hispanic Protestants, and white non-Hispanic Catholics. A respondent without a born-again answer is in neither white Protestant group. Windows are 1980 to 1988, 1992 to 2000, 2008 to 2012 and 2016 to 2020. The vote is the reported two-party presidential vote of voters, and party identification is pid_7pt 1 to 3 against 5 to 7 among all respondents. The weight VCF0009z is 1 for every respondent from 1980 to 1990 and is rescaled to average one within each study among voters or among party identifiers. The 2012 and 2016 studies add web samples and the 2020 study was collected online, by telephone and by video, with no mode weights for 2020, so the last windows mix interview modes.

Survey mode. The CES is online in every year. GSS survey years from 2021 include web interviews; the 2021 to 2022 window is flagged in the figure and the text, and the 2022 split by mode is reported for white RELTRAD evangelical Protestants. The GSS rows of the coding check use the surveys of 2006 to 2018 in all the interview modes those surveys used, which include some telephone interviews.

What these data cannot show

Each survey interviews a different sample, so the gaps compare groups and say nothing about any voter changing.
Religious behavior and identity respond to politics as well as the reverse.
Panel studies find that partisan identity shapes whether people identify with a religion and how often they attend [5] [6].
A gap between seldom and frequent attenders, or a difference between traditions, can therefore reflect people moving between groups, and the decomposition splits an observed gap into parts without saying what would happen if the mix of attenders changed.
Tradition in the CES is a proxy for denomination.
The CES cannot separate Baptist, Methodist, Lutheran and non-denominational respondents, cannot place Black Protestants by denomination, and cannot tell Pentecostal from other Hispanic Protestants.
The GSS codes tradition by denomination but stops in 2022, records Hispanic origin only from 2000, and leaves 5.3% of respondents in 2010 to 2018 unplaced.
The ANES 2024 rows of the coding check have wider intervals than the CES rows, and the ANES sample is too small to give a Hispanic Protestant estimate at all.
The levels depend on the survey and the weight.
The CES estimates use the cumulative-file weight because it is the one CES weight defined for all five elections; the validated-vote weight exists only for 2018 to 2024.
In 2024 it gives 34.1% (95% CI 32.4% to 35.8%) for white Catholics against 37.1%, 13.2% (95% CI 11.9% to 14.4%) for white born-again Protestants against 14.5% and 59.6% (95% CI 53.9% to 65.2%) for Hispanic Catholics against 57.0%.
The CES national Democratic share is 49.0% with the cumulative-file weight and 49.1% with the validated-vote weight, against a certified 49.2%.
Agreement at the national level does not show that a survey is accurate inside a tradition and race.
The ANES group levels exceed the CES levels by the most for white Protestants who are not born-again and Hispanic Catholics, and by more than the two national shares differ.
Small groups carry intervals as wide as the Muslim estimate, and the figures draw those intervals; the only cells removed are those under the floor.
The sample is voters who reported a Democratic or Republican vote, so nonvoters, third-party voters and respondents who did not answer are outside it.
The chapter has no measure of belief, congregation, region or age, and nothing in it identifies why Black Protestants and white born-again Protestants vote as they do.
The growth of the unaffiliated and their subtypes belong to Planned, The rise of the nones (https://vishalsingh.org/politics/the-rise-of-the-nones; planned), and the link between attendance and moral attitudes to Planned, Two moralities (https://vishalsingh.org/politics/two-moralities; planned).
