- ACS 5-year
Geographies
- United States
- Public Use Microdata Area (PUMA), using the selected release’s documented native boundaries

Uncertainty and reliability
- When results are withheld
- Results are withheld when fewer than 351 survey records are included in the denominator. Medians are also withheld when the replicate method produces a standard error at or very near zero.
- When to use caution
- Results are marked unstable when the standard error exceeds 30% of the estimate's absolute value. This is the relative standard error (RSE). Use these estimates with caution.
Survey weights used: PWGTP and PWGTP1–PWGTP80
