The Knivsta Municipality is often thought as expansive, because of the frequent immigration, mostly to the nearby town of Alsike.

Milles's statue by the Lagga church represents angels playing at his mother's grave.

Other famous residents include composer Emil Sjögren, and artist Olof Thunman, whom Knivsta's largest school has been named after.

Thunman's works include, for example, Vi gå över daggstänkta berg.

These clubs are active in handball, football, table tennis, skiing, bandy and many more.
