Home values set most of the deprivation ranking

Scene 3 of 19, step 1 of 2: Raw units. Census tracts, weighted by population.

What to say

Two statistics appear here and they are different: the variance of the home value term alone, and its share once the covariance with income is allocated. Do not substitute one for the other. The standardized index changed only one of the main gradients counted in the book, traffic pollution.

About the chart

In raw units home value and family income carry 99.2% of the variance of the score between them

Home value's bar is the longest and family income's the second; every other bar is nearly zero.

  • Raw units: dollars for the four dollar measures, proportions between zero and one for the rest, and the log ratio for income disparity, as the Atlas applies Singh's coefficients. Standardized: each measure minus its population-weighted mean over its population-weighted standard deviation.
  • The two measures that are not rebuilt (high school diploma and internet access) are proportions, so in raw units they would add little to the variance of the score.
