State geography workflows

Find and compare counties

Use each state's county-reference page for names and FIPS codes, What County Am I In? for a single point, or the County Demographic Explorer for state-wide comparison.

Work with ZIP and population data

Combine ZIP lookup, ZIPs within radius and Population within radius for Census-based local context.

Sources and interpretation

State and county pages use US Census-derived cartographic geometry for visualization. Demographic tools use Census and American Community Survey data where stated. MapBench distinguishes statistical geography from legal or surveying boundaries and documents approximation methods on each tool or study page.
