Every year, about 10 million Americans move from one county to another. Migration rates vary by age, sex, race, and ethnicity and with local and national social and economic conditions over time. Examining patterns of net-migration for individual counties over time provides important information about how local populations are changing. This webinar introduces a new publicly available website (www.netmigration.wisc.edu) where users can generate maps and charts of state and county level net migration using six decades of data. The data are available for download providing reliable estimates of net migration broken down by age, race, Hispanic-origin, and sex for all U.S. counties for each decade from 1950 to 2010.


In the webinar, Richelle Winkler, assistant professor of sociology and demography at Michigan Tech University, and Katherine Curtis, associate professor of community and environmental sociology at the University of Wisconsin-Madison, discuss the background of how the data were constructed, demonstrate the website’s utility, and provide select examples of how the data can be used to understand community change. Their discussion is followed by 10 minutes of questions and answers.
