Micropolitan Statistical Areas (μSAs) are geographic regions in the United States that typically consist of a core city with a population between 10,000 and 50,000 people, along with surrounding areas that are economically and socially linked to that city. These areas are used by the U.S. Census Bureau to analyze population trends and economic conditions. μSAs are important for understanding local economies and community dynamics, as they often include smaller towns and rural areas that rely on the core city for jobs and services. They provide a more detailed view of regional development compared to larger metropolitan areas, highlighting the significance of smaller urban centers in the national landscape.
