US ethnic groups, from state to census tract

Zoom switches levels automatically: state (≤3) → county (4–6) → city (7) → ZIP (ZCTA) (8–10) → census tract (≥11); metro areas (CBSA) can be locked manually. ACS 2020–2024 5-year estimates, 69 groups.

Thresholds (selected group's count)

Thresholds adapt to each group (higher for large groups, lower for small ones) and reset to the group's default when you switch groups. Only units with ≥ 20 people are stored, so 20 is the lowest setting.
