Local research workflow planning checklist

  1. State the county FIPS and the sources the agent may read.
  2. Define the expected report, schedule and review owner.
  3. Record the allowed actions, recurring costs and recovery test in the commissioning scope.

A county page is not a commissioned agent deployment or a promise of local field service.

Sources and interpretation

Geography: 2025 U.S. Census Gazetteer. Population: Vintage 2025 estimates, July 1, 2025. County equivalents include parishes, boroughs, independent cities and planning regions. Puerto Rico population is not supplied by this population file.

Population is an estimate, not a live count. Gazetteer land and water measures describe the geographic area; they do not measure service availability, households, businesses or market demand. Match the FIPS code and source vintage when joining another dataset.
