Differential Privacy and the Accuracy of County-Level Net Migration Estimates.

Each decade since the 1950s, demographers have generated high quality net migration estimates by age, sex, and race for US counties using decennial census data as starting and ending populations. The estimates have been downloaded tens of thousands of times and widely used for planning, diverse applications, and research. Census 2020 should allow the series to extend through the 2010-2020 decade.

Tracking Urbanization and Exurbs: Migration Across the Rural-Urban Continuum, 1990-2016.

This paper summarizes annual migration patterns across the rural-urban continuum in the USA between 1990 and 2016. We introduce a modified rural-urban continuum classification, the Rural-Urban Gradient (RUG). The RUG holds metropolitan classification constant, effectively designates exurbs, and distinguishes central city core counties in major metropolitan areas from their suburbs and exurbs.

Moving Toward Integration? Effects of Migration on Ethnoracial Segregation Across the Rural-Urban Continuum.

This study analyzes the impact of migration on ethnoracial segregation among U.S. counties.

Migration signatures across the decades: Net migration by age in U.S. counties, 1950-2010.

Background: Migration is the primary population redistribution process in the United States. Selective migration by age, race/ethnic group, and spatial location governs population integration, affects community and economic development, contributes to land use change, and structures service needs.

Objective: Delineate historical net migration patterns by age, race/ethnic, and rural-urban dimensions for United States counties.
