Millions of Americans move to different counties each year. Tracking who is moving and where they're going can be difficult to quantify and visualize, but these gloriously detailed interactive maps from the University of Wisconsin manage the task with ease.
Quite incredibly, about 10 million Americans move to a different county every year. These migration rates vary significantly by age, race, and ethnicity — not to mention the social and economic factors that motivate people to pack their bags and go. At the same time, some counties' patterns tend to be consistent over time, which often tells a different story altogether.
The new website, Net Migration Patterns for US Counties, has compiled zoomable maps of net migrations broken down by age, race, Hispanic-origin, and sex for all U.S. counties each decade from 1950 to 2010.
From the website:
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.
Here are some screengrabs showcasing some of the more interesting and revealing maps. As the legend notes, deeper orange represents more people who moved away than moved into a county, and deeper purple shows the opposite.
People across all demographics are moving from the inner areas to the coast.
And awesomely, all the data is downloadable.
