Start with the map to see where residents live across the five counties. Switch between the 2024 population estimate and percentage change since 2010; the comparison bars show each value on a shared scale. Lea had the largest estimated population in 2024 (75,151), while Lincoln had the smallest (20,025). Color identifies the county, and map area represents geography rather than population.

Sources and Map Notes
County boundaries are from the U.S. Census Bureau, January 1, 2024. This is a county comparison, not a map of neighborhoods, parcels, tribal jurisdiction, or hazard zones. County totals include residents of the Mescalero Apache Tribe within those boundaries.
