Metropolitan Statistical Area

A Metropolitan Statistical Area (MSA) is a geographic region defined by the U.S. government for analyzing urban growth and population. It typically includes a core city with a large population, plus surrounding neighborhoods and towns that are economically and socially connected through commuting and shared services. MSAs help planners and researchers understand regional patterns, such as economic activity, transportation, and housing trends. They are useful for policy making, business decisions, and statistical reports, providing a comprehensive view of urbanized areas and their surrounding communities.
