1 minuteDo short-run weather shocks affect migration? I estimate how snow influences county-level migration in the Great Lakes region since 1970. I isolate responses to snow by comparing its effect on net migration across regions exposed to lake-effect snow (LES)-heavy snow generated downwind of the Great Lakes. Higher-than-average snowfall in lake-effect regions leads to net population loss the following year. This effect is driven by reductions in in-migrants, dissipates after 1-2 years, and is strongest for young and middle-aged populations. Snow has virtually no effect on migration in non-lake-effect regions, suggesting that baseline exposure interacts with anomalous weather events.
