Short-Haul Moves and the Political Geography of Partisanship: Intrametropolitan Migration as a Force for Change in U.S. Politics
Urban Affairs Review · 2026
Short-distance moves within metropolitan areas contribute modestly but meaningfully to partisan geographic sorting.
View abstract +
We consider how the high volume of short-distance migration within metropolitan areas contributes to partisan sorting across the United States. Using voter records comparing movers and nonmovers within 215 metro areas across nine states, we find high levels of sorting even when moves occur within the same core-based statistical area and state. Short-distance moves contribute modestly but meaningfully to the growing political lopsidedness of many legislative districts between censuses.
