Method notes

Census treats race and Hispanic/Latino origin as separate questions. Race categories other than Hispanic reflect total populations (small Hispanic overlap in Black, Asian, AIAN, NHPI). “Multiracial / Other” is derived as a non-overlapping remainder.

Click rows to expand ancestry detail. Ancestry from ACS B04006, B03001, B02020, B02016. Totals may differ from race — individuals can report multiple ancestries.

Black / African American (estimated remainder) is derived as Black population share minus reported Sub-Saharan African and West Indian ancestry. It is shown as an estimated ancestry detail, not a standalone Census ancestry category.

MENA estimated from ancestry reporting — Census does not have a separate MENA race category. Not shown in bar (overlaps with other race groups).

Catholic-Evangelical edge: -66.6pp (vs national 4.5pp). A strongly Evangelical-leaning religious profile, which nationally correlates with Republican-leaning rural and exurban communities.

Ecological pattern — how to read this

Reflects patterns in counties where this religious tradition concentrates — not a claim about individual voters.

Values are derived by joining Religion Census 2020 (U.S. Religion Data Archive) with certified election results at the county level. That means we know what counties with more or fewer of this group did — not how any individual voted.

This is known as ecological inference. It is a valid way to surface geographic correlation but must not be read as a personal-vote claim about anyone in the group.
