What it’s like
The place. Groton is a small city in Brown County, South Dakota, with a younger population than many small towns, and most homes here are lived in by their owners. Few residents live below the poverty line, and a four-year degree is held by a fair number of adults. Winters are cold, with January the coldest month, summers are warm, and the year brings a modest amount of rain and melted snow.
Work. Residents work mostly in schools, hospitals and social care, followed by shops, manufacturing, and farming, forestry and mining. Across Brown County, some of the largest workplaces are Avera St. Lukes, Aberdeen School District 06-1 and 3M Company. The commute is short, few people work from home, and unemployment in the county is low, though the county has lost a small share of its jobs over the past year.
Things to do. For time outdoors, Sand Lake National Wildlife Refuge is a protected area and Kuhnert Arboretum is a botanical garden, each a longer drive away. Lynn Lake is a lake, also a longer drive away. Those who like a museum stop can visit the International Vinegar Museum, which is likewise a longer drive from town.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Groton’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. More on Brown County and the Aberdeen, SD metro.
