Net Migration
Definition
The difference between the number of people entering and leaving a geographic area over a period. Positive net migration means more people moved in than out; negative means more left.
Why It Matters
Net migration reveals which areas are gaining or losing population due to movement rather than births and deaths. It reflects economic opportunity, quality of life, cost of living, and policy attractiveness.
How It's Measured
Estimated by comparing population change to natural increase (births minus deaths). The difference is attributed to migration. Also tracked through tax return data and visa records.
