What it’s like

The place. Corsica is a very small city in Douglas County, South Dakota, where neighbors are likely to know one another. Household incomes in the county are comfortable, and few residents fall below the poverty line. Winters are cold, with January the coldest month and plenty of snow, while July brings real warmth. Precipitation is moderate through the year.

Work. Residents work mostly in schools, hospitals and social care, in farming, forestry and mining, in the building trades, and in shops. Few work from home. The largest workplaces in town include Corsica-Stickney Schools, Dakota Tom's Sandwiches, a maker of fresh sandwiches, and C & B Operations Corsica, a wholesaler of agricultural machinery and equipment. Unemployment in the county is low, and the county has added jobs over the past year.

Things to do. Simpson Lake, in or beside town, is the closest spot for time by the water. A longer drive away are Lake Francis Case, a large reservoir, and Lake Andes National Wildlife Refuge, a protected area for wildlife watching. Fort Randall, also a longer drive away, is a historic fort.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Corsica’s census tracts, against the rest of the country; all of them together, relatively high. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.

From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out.
