We know that millions of Americans move to different counties every year, and when you look at the net totals, you see a pattern of people migrate from the midwest to the coasts. However, look at migration across demographic categories, and you see more detailed movement. This was the goal of researchers at the University of Wisconsin-Madison, and they recently released their estimates, in map form.
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.
