Population over time

2 figures

Clayton grew from 15,939 to 17,355 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

September 2008Flash FloodClayton3 killedThe remnants of Hurricane Ike moved through the midwest dumping between 3 and 6 inches of rain in just under 6 hours on already saturated soils. This caused widespread flash flooding over St. Louis County. One of the hardest hit areas was University City. Two people drowned in University City when trying to move their vehicles away from the rising flood waters. Another person was killed when a large tree limb that was struck by lightning fell on her in Ladue. Other areas affected by the flash flooding were Hazelwood, Ferguson, Brentwood, Maplewood, Rock Hill, Webster Groves, and Florissant. Over 600 homes, apartments and business were affected by the flooding. Numerous water rescues had to be performed when people drove their vehicles into flooded roadways and became stuck in the flood waters.
