American Migration

By Jon Bruner | Forbes

Bruner’s interactive visualization, based on IRS data, illustrates inward and outward migration for every U.S. county. Each move had its own motivations, but in aggregate they ­reflect the geographical marketplace during the boom and bust of the last decade: Migrants flock to Las Vegas in 2005 in search of cheap, luxurious housing, then flee in 2009 as the city’s economy collapses; Miami beckons retirees from the North but offers little to its working-age residents, who leave for the West. Even fast-growing boomtowns like Charlotte, N.C., lose residents to their outlying counties as the demand for exurban tract-housing pushes workers ever outward.

Last year I participated in WNYC’s ‘Map Your Moves‘ data visualization challenge, rendering a very similar map of migration patterns.

Matthew Bloch and Robert Gebeloff at The New York Times have designed a wonderful choropleth map of U.S. migration data going back to 1880. The user can select the origin of various immigration groups to see how they settled across the United States. A time slider provides an easy way to animate the data, either as percent of population, or in number of residents.
