    "County Health Rankings publishes a county's infant mortality rate only from {fact:map_floor_deaths} infant deaths in the period, which leaves out most small counties and is the same floor the book uses for death maps. Gray counties are not zero; they are counties where the rate cannot be published.",
    "The period is 2015 to 2021, not the 2018 to 2022 of the WONDER figures. Across the {fact:counties_used} large counties the two sources correlate at {fact:chr_lbd_corr}.",
    "The key runs from {fact:map_key_low} to {fact:map_key_high}, the fifth to ninety-fifth percentile of the mapped county rates. Counties beyond either end take the end color, so the end colors include the tails of the distribution.",
