2010 U.S. Census data shows that 12 San Gabriel Valley cities, including Arcadia, saw the percentage of owner-occupied homes rise, something that experts said was extremely uncommon following the housing crisis. 63.1% of Arcadia's homes are owner-occupied, while 36.9% are occupied by renters. Other cities' figures are shown in chart. Arcadia's vacancy percentage is 5.3%. Vacancy rates are determined by the U.S. Census Bureau by sending out canvassers to homes that did not respond to Census mailers.
