County-to-County Migration in Missouri

This month’s story map, created by Morgan Hurt of the Missouri Spatial Data Information Service, examines recent inward and outward migration to and from Missouri counties.

The data comes from the 2015-2019 American Community Survey — specifically, county-to-county migration flows, a special tabulation created by the ACS program. This data is not released every year, which is why we don’t yet have this migration data from the newest ACS data release (2017-2021).

Missouri Census Data Center frequently works with MSDIS on mapping and data projects. MSDIS is a spatial data retrieval and archival system offering many mapping resources, primarily focused on the state of Missouri.

Nearly One in Five Movers Relocate to a Different Metro Area

About 18% of all movers in the United States and Puerto Rico, totaling 8.5 million people, moved to a different metropolitan area in the last year, according to new statistics released today by the U.S. Census Bureau. This is the first time that the Census Bureau has released statistics for movers between metro areas from the American Community Survey.

The migration flows tables, which use data collected between 2009 and 2013, show how many residents move from one county or metro area to another during the course of a year. Government officials and planners, as well as local businesses, use these statistics to understand residential turnover in their communities. They also use this information to plan for infrastructure for new residents when there is a trend in people arriving, or to plan programs that attract new residents or employers when there is a trend in people leaving.

Nine of the top 10 metro migration flows were moves to nearby metro areas, with the largest flow of about 90,000 moving from the Los Angeles metro to the Riverside metro area. Movers who left the New York City metro area for the Miami metro area were the exception, with about 22,000 people making this move.

In addition to the new metro-to-metro migration flow tables, the annual county-to-county migration flow tables are now available. The county flows can also be accessed through the Census Flows Mapper.

The migration flow tables for both county-to-county and metro-to-metro include characteristics of movers by ability to speak English, place of birth, and years living in the United States.
