Each dot represents 100 reported ancestries. United States data is from the American Community Survey (2020 to 2024 5-year estimates, by census tract); Canadian data is from the 2021 Census of Canada (ethnic or cultural origin, by dissemination area).

Dots are placed randomly within each area's land.

You can customize colors by clicking the colored dot in the legend!

Double clicking a dot on the map will filter to just that origin.

People can report more than one origin, so each dot is one reported origin, not one person. The US survey allows up to two origins per person; the Canadian census kept up to six.

* Note: The two "no reported ancestry" groups don't reflect specific census data. Rather, they are my crude estimates that attempt to count some of the people who do not report ancestry. Black, no reported ancestry is calculated per census tract as the black (race) population minus all the ancestries in the African and West Indian groups. White, no reported ancestry is analogously the white (race) population minus the European and North American groups.
