Definition
The difference between the number of people entering a geographic area and the number of people leaving that area over a specific period, usually expressed as a rate per 1,000 people. It indicates overall population gain or loss due to movement.
Why It Matters
This is a key indicator of whether a region is attracting or losing population, reflecting its economic dynamism, quality of life, and future growth potential. It influences housing demand, labor supply, and service provision.
Specific Relevance for Professionals:
Marketers
Critical for identifying growth markets for business expansion versus declining markets. Positive net migration signals a growing customer base, justifying increased investment in advertising and distribution.
Researchers
Fundamental for demographic forecasting, studying the drivers of population change beyond births and deaths, and analyzing the impact of migration on regional economies and social structures.
Consultants
Crucial for advising clients on investment in real estate, retail, or service industries. A consultant might recommend investing in areas with strong positive net migration for long-term growth.
Public Policy Workers
Paramount for urban and regional planning, forecasting future demands for infrastructure (e.g., schools, roads), and informing policies aimed at attracting or retaining residents to support economic development.
