Maps offer neighborhood-level insight into American migration | Cornell Chronicle

"That local exodus is documented by Cornell-led research that mapped annual moves between U.S. neighborhoods from 2010 to 2019 in detail 4,600 times greater than standard public data. Called MIGRATE, the new, publicly available dataset revealed that most of those displaced remained within the affected county - moves not captured in county-level public migration data aggregated every five years."

"About 44 million people move every year in the U.S., but most of those moves are invisible in official data. "MIGRATE reveals trends that shape daily life that broader data completely miss: rising moves into top-income neighborhoods, racial gaps in upward mobility and local shocks like post-wildfire outmigration," said Maria Fitzpatrick , professor in the Department of Economics and the Cornell Jeb E. Brooks School of Public Policy. "For communities, journalists, researchers and planners, it's a trustworthy, neighborhood-level lens on climate risk, housing pressure and opportunity - available for nonprofit research use.""

MIGRATE maps annual moves between U.S. neighborhoods from 2010 to 2019 at roughly 4,600 times the spatial detail of standard public migration data. The dataset shows that the 2018 Camp Fire forced nearly half of residents living within designated fire perimeters to relocate within a year, with most displacements remaining inside the affected county and thus omitted from five-year county-level migration statistics. MIGRATE makes neighborhood-level migration patterns publicly available, revealing trends such as rising moves into top-income areas, racial gaps in upward mobility, and local outmigration after wildfires, informing climate risk, housing, and policy analysis.
