Platte County sits along the Missouri River just north of Kansas City, and its suburban growth has tightened presidential margins from double-digit Republican advantages a decade ago to single digits in 2024.
The county's recent history is a story of close margins. The Democratic margin reached sixty-three points in 1932; the Republican margin reached thirty-five points in 1972. Most other elections have been decided by single-digit points.
Platte County's demographics — a population of 110,371, a 79% non-Hispanic-white share, a median household income of $96,227 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Kaufman County and Scott County.
