Des Peres has grown from an initial population of 550 at time of incorporation in 1934 to a present day population of 8,592 (2000 Census). That growth is a result of both new home construction and major annexations of residential areas to the west and south of the original city in 1973 and 1975 as well as smaller annexations in 1999. The city has set its ultimate boundary west of Barrett Station Road to the centerline of Grand Glaize Creek but the city is not actively pursuing that annexation.
