The City of Maricopa has been in explosive growth mode since 2000. People discovered the town (it became a city since then) was reasonably close to Chandler, Tempe and Phoenix, and decided that much more affordable housing, open spaces and a small community feel were more important than a long commute. Well, the secret is out, and the city is now booming, with city services, retail and construction doing their best to keep up.
The population of Maricopa was 15,934 (2005 Special Census). The Arizona Department of Economic Security estimates that the population number at July 2006 was approximately 24,625 and the City of Maricopa estimates that the population has swelled to about 34,000 as of September 2007, based on school enrollment, residential permits and final occupancy inspections and other factors.
Because the demographics of the City of Maricopa have changed so dramatically since the 2000 census, I am unable to provide logical, current information on educational attainment and median incomes. I think it is safe to assume that those levels have risen since 2000, since the influx of population is probably considered educated and middle-class.
