Where Are Your County's Residents Moving to and from?

Regions in the southwest, Colorado and Florida added the most residents in 2011.

Millions of Americans move to different counties every year, from relocating to neighboring towns to moving all the way across the country.

New Census Bureau data published this morning shows where each county’s residents are moving to or from. Detailed migration flow estimates for each county are listed on the Census Flows Mapper tool.

The Census Bureau identified several migration hubs throughout the country adding the most residents, particularly regions of the southwest, Colorado and Florida.

New population estimates also include those migrating from abroad. More than 35,000 people moved from Asia to Los Angeles County, Calif., in 2011, for example.

Migration patterns for the more populous U.S. counties suggest a continuing population shift from counties encompassing major cities to neighboring jurisdictions.

The following table shows the top 25 county-to-county net migration flows, with totals representing approximate annual averages for 2011:
