What it’s like

The place. Martinsburg is a very small town in Audrain County, Missouri, where nearly all homes are lived in by their owners. Few adults here hold a four-year degree, and typical home values sit at a modest level. Winters are cold, with January highs a little above freezing and lows well below it, while July brings hot summer days, and rain and melted snow fall steadily through the year.

Work. People in town work mostly in schools, hospitals and social care, with others in manufacturing, shops, and transport, warehouses and utilities. Across Audrain County, the largest workplaces include Mexico 59 Schools, Spartan Light Metal Products and Walmart. Unemployment across the county is lower than a year ago, though the county has fewer jobs than it did the year before, and household incomes there are modest.

Things to do. The Loutre River, Bachelor Creek and Lost Creek are all a short drive away, for time by the water. Farther afield, Graham Cave State Park is a protected area a longer drive away, and the Mark Twain Birthplace State Historic Site is also a longer drive, both worth a day out.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Martinsburg’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 Audrain County and the Mexico, MO metro.
