Clifton is a typical middle class urban neighborhood. There has been some restoration of older homes, particularly in the Clifton Heights subdivision area. An active improvement association aids in maintaining good environmental standards. The population of the Clifton area has declined since 1960. Alignment of Highway 44 along the River des Peres, instead of a more northerly course, took out a considerable number of residences. However, the cause of the decline seems to be more general than that, and is possibly due to population shifts created by family changes among older residents.
