Arden Arcade is a 16-square mile Census Designated Place (CDP) that lies east of the City of Sacramento in Sacramento County in California's Central Valley. The population in 2010 was 92,186 (US Census data); that made us the 2nd-largest CDP in California. As of 2019 the Census models predicted we would have slightly over 100,000 residents. The official 2020 Census number is now stated as 94,659 - probably an undercount given the 2020 Census controversies over immigration and homelessness and considering the massive influx of very recent refugees from Afghanistan. Still, 95,000 is a significant number of people. And, with a population density of 5900 people (or more) per square mile, Arden Arcade is a heavily urbanized area.
