In case you needed more evidence of Pinal County’s population boom, the U.S. Census Bureau reported in May that Casa Grande, Maricopa and Queen Creek were all among the nation’s fastest-growing cities in 2021.
The City of Casa Grande’s growth rate of 6.2% just outpaced the City of Maricopa’s of 6.1%, according to the bureau’s calculations based on administrative records, geographic boundaries and other data.
They came in at No. 7 and No. 8 on the list of fastest-growing cities and towns with populations more than 50,000. The Town of Queen Creek, of which a small populated portion is in Pinal County, sat at No. 3 with an 8.9% increase.
Unincorporated San Tan Valley just south of Queen Creek, the county’s largest population center in 2020 at almost 100,000, was not included in this listing.
Casa Grande now has an estimated population of 57,699, while Maricopa’s is 62,720. In the 2010 census, Casa Grande’s recorded population was 48,571 and Maricopa’s was 43,482.
More Arizona cities figured prominently in these latest bureau lists, with Buckeye and Goodyear also making the top 15 in terms of percentage gain and Phoenix and Buckeye in the top 10 for numerical population growth.
These figures are something of a reversal of fortune for Casa Grande, where some officials felt the 2020 census total of 55,658 was an undercount. It appears to be headed for more growth as Lucid Motors expands and companies like Kohler and Chang Chun Petrochemical Group commit to building plants here.
Decennial Census counts such as 2020’s are used to determine population-based funding for most federal programs, while estimates for other years play a lesser role in funding allocation, conducting surveys and other research.
