This document summarizes information about local governments in the United States. It notes that there are over 3,000 counties, 19,000 municipalities, and 16,000 townships that provide local services. Municipalities range greatly in population size from just 1 person to over 8 million. Smaller municipalities with populations under 4,000 often lack online staff directories and services. Larger cities may have open data portals but populations under 65,000 may not have reliable 1-year American Community Survey population estimates. The document outlines challenges with federal and state reporting requirements and accessing granular data and information for local governments of all sizes.
