Sandusky, MI

Sandusky is Sanilac County's seat and largest city, with 2,709 residents at the 2020 census. It sits near the center of the county in Michigan's Thumb, a position that makes courthouse work the town's main geographic fact. Sandusky began as a village and became county seat in 1879, after the county's government needed a fixed home. The city is part of the wider Thumb and Blue Water map, with farms and small towns radiating out from it. The courthouse, school buildings, and farm roads keep that county role visible through the week.

Today Sandusky Community Schools cover the local school map with elementary and junior-senior high buildings, and the city's sports teams play in the Big Thumb Conference. That gives the town a recognizable daily rhythm beyond the courthouse: school buses, farm roads, and county errands all meet in one place. Sandusky is not the lakeshore city its name might suggest; it is an inland county-seat town whose role comes from location, government, and the surrounding agricultural Thumb.
