Brookings County, South Dakota

Geography and landscape

Brookings County lies in a region of rolling prairie and fertile soils that supports extensive farming. The landscape combines cropland, pasture, small woodlots and developed urban areas. The county forms part of the agricultural belt of eastern South Dakota and is served by a network of regional highways and local roads that connect towns and farms to larger markets.

History and development

The area that became Brookings County was created by territorial legislation in 1862 and formally organized in 1871. Settlement accelerated in the late 19th century with the arrival of railroads and immigrant farmers. Over time the county evolved from a frontier agricultural area into a mixed economy with education, research and light industry contributing alongside traditional farming.

Economy and institutions

Farming remains a major economic base; typical crops include corn, soybeans and small grains, with livestock operations also present. A significant non‑agricultural influence is higher education: the city of Brookings is home to South Dakota State University (SDSU), the state's land‑grant research university, which brings students, research, and healthcare and cultural services to the county. Major sectors include:

• Agriculture and agribusiness
• Education and research
• Healthcare, retail and light manufacturing

Government, services and transportation

The county government administers local services from offices and the courthouse in the county seat, Brookings (county seat). Transportation links include an interstate corridor and regional highways that facilitate travel to larger South Dakota cities and neighboring states. Public and private services center in the city of Brookings and in several smaller towns and townships across the county.

Communities and notable facts

Brookings County comprises the city of Brookings plus a number of smaller towns, rural townships and unincorporated settlements. It forms the core of the Brookings Micropolitan Statistical Area.
