Spanning over 23,000 square miles of roadless tundra and coastline, Lake and Peninsula Borough is one of Alaska's least-populated boroughs, where Alaska Native communities make up a majority and subsistence hunting and fishing remain central to daily life.
The Democratic margin in Lake and Peninsula Borough has rarely exceeded nineteen points in modern history; the Republican margin has rarely exceeded sixty points. 2024 delivered the county to the Republican candidate by ten points.
Lake and Peninsula Borough's demographics resemble the country more than they resemble most counties. A 17% non-Hispanic-white share, a 13% poverty rate, and a median household income of $65,625 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Dillingham Census Area and Oktibbeha County.
