What it’s like

The place. Augusta is a very small town, and almost everyone who lives there owns their home, a far higher share than across most of the country. Homes are valued well above what is typical nationally, and few residents live below the poverty line. Winters are cold, with January highs near freezing and lows well below it, and some snow most years; summers are hot, and rain falls steadily through the year.

Work. Residents work mostly in schools, hospitals and social care, with others in manufacturing, professional and business services, and shops. Across St. Charles County, some of the largest employers are General Motors Wentzville, Amazon and Lindenwood University. The typical commute is a long one, and a good number of people skip it by working from home.

Things to do. Klondike Park is in or beside town, and Shaw Nature Reserve, a botanical garden, is a short drive away. Charrette Creek, a river, is also a short drive away. For a bigger outing, Mid America Adventure, an amusement park, is a longer drive.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Augusta’s census tracts, against the rest of the country; all of them together, relatively moderate. 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 St. Charles County and the St. Louis, MO-IL metro.
