Only a dozen cities in Arizona have reached this milestone — but Maricopa is among the next on deck.
Maricopa reported fewer than 60,000 residents in the most recent 2020 census. Today, the population has already eclipsed 70,000, marking 19% growth in just two years.
The city’s 6% annual growth rate is expected to climb gradually over the next six years. In 2029, the population is projected to be 100,500.
At just 20 years old, Maricopa has already surpassed Casa Grande — a century-old city — to become the most populous municipality in Pinal County.
Only Phoenix, Tucson, Mesa, Chandler, Gilbert, Glendale, Scottsdale, Peoria, Tempe, Surprise, Buckeye and Goodyear boast populations over 100,000.
