About Net Migration

Lower 48 net migration map

Every year, about 10 million Americans move from one county to another. Migration rates vary by age, race, and ethnicity and with local and national social and economic conditions over time. Still, individual counties' patterns of age-specific migration tend to be consistent over time telling demographic stories about local places. This website highlights these stories by providing reliable estimates of net migration broken down by age, race, Hispanic-origin, and sex for all U.S. counties each decade from 1950 to 2010.

Click on the tabs above to make maps and charts that allow you to visualize migration patterns. Charts make it easy to compare migration patterns over time within a single county or to compare patterns in two or three different counties for the same decade. Maps show how counties across the country compare to one another. The data download tab allows you to download migration data as well as census data for your own analysis.
