What it’s like
The place. Saint Mary is a very small city in Ste. Genevieve County, Missouri, where neighbors are likely to know one another. Homes here are valued somewhat above what is typical for the county's household incomes, and the surrounding countryside gives the place a quiet, rural feel. Few adults hold a four-year degree compared with much of the country. Winters are cold, with January highs near freezing and lows well below it, and only a little snow falls in a year. Summers turn hot by July, and rain arrives steadily through the year.
Work. Residents work mainly in schools, hospitals and social care, with manufacturing, the building trades, and professional and business services close behind. Across Ste. Genevieve County, some of the largest workplaces are Ste. Genevieve County Memorial Hospital, the Ste. Genevieve R-II Schools and the excavation contractor Heptacore. Unemployment across the county is low and has eased over the past year, and the county has added a few more jobs than it had the year before.
Things to do. Saline Creek runs in or beside town, and the Kaskaskia River and Marys River are a short drive away for time near the water. History is close at hand too: Fort Kaskaskia State Historic Site and the Felix Vallé House State Historic Site are both a short drive off. The Middle Mississippi River National Wildlife Refuge, also a short drive away, protects a stretch of the big river's wild country.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Saint Mary’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 Ste. Genevieve County.
