The net gain or loss of population due to migration specifically into or out of Metropolitan Statistical Areas (MSAs).
This is a key indicator of the magnetic pull of major urban centers. It reflects whether MSAs are attracting population (growth) or experiencing outflow (decline), influencing economic development and urban planning.
Specific Relevance for Professionals:
Marketers
Crucial for identifying growth markets for businesses operating in or around major metropolitan areas versus those experiencing decline. High net migration signals growing consumer bases.
Researchers
Fundamental for studying urban growth, sprawl, counter-urbanization, and the economic and social factors driving population flows to/from major metropolitan centers.
Consultants
Paramount for advising clients on investment in urban real estate, retail expansion in metro areas, or assessing talent pool growth in major economic hubs.
Public Policy Workers
Vital for urban planning, forecasting demand for metro infrastructure (e.g., transit, housing), and informing policies aimed at managing urban growth or revitalizing declining metro areas.
