The Applied Population Lab (APL), housed in the Department of Community and Environmental Sociology and with funding from UW–Madison Extension, recently launched an updated net-migration online tool called Net Migration Patterns for US Counties. The tool provides reliable estimates of net migration broken down by age, race, Hispanic origin, and sex for all U.S. counties and states each decade from 1950 to 2020.

The tool shows that migration rates vary by age, race, and ethnicity and with local and national social and economic conditions over time. Nonetheless, individual counties’ patterns of age-specific migration tend to be consistent over time, telling demographic stories about local places, which can be explored with this online tool.

Net Migration Patterns for US Counties was developed in collaboration with Michigan Technological University and University of New Hampshire. View it here.
