It is a semi-rural municipality with several working farms, large areas given over to fields and forests, although there is a major industry of sand extraction, now mostly in decline.

Due to this history there are now several haulage and construction firms based in the municipality.

Chaumont-Gistoux is on the KW-line, a defensive line erected early in the Second World War, intended to prevent invasion from Nazi Germany.

The Coombs family still resides there to this day, and the Princess, her husband Prince Laurent and their children are often seen in the municipality.
