How these figures are made
- Residents and housing are estimates of the April 1, 2020 Census count, added up from census tracts. A tract on the edge counts by the share of its land area inside the circle, and estimates are rounded to three significant figures.
- Town and ZIP populations are 2020 Census counts for the whole place or ZIP code area. Each is listed when its center point is inside the circle, so part of it may lie outside.
- Distances are straight lines from the center point, not road miles. A circle crosses state lines and shorelines. The Census covers only the United States, so any part of a circle across an international border adds no residents, towns or ZIP code areas.
The radius map tool page explains the method, how it was tested and its limits.
