Method and limitations

The displayed total is the ACS Data Profile DP05_0001E direct total-population estimate.

This is a five-year ACS survey estimate, not a decennial census count. DP05_0001M is the ACS 90-percent-confidence MOE. null estimate with source state valid, missing, suppressed, or invalid; zero remains valid. Five equal-width color bands span the valid values in this state; colors are not comparable across states.
