Maricopa County, Arizona
Maricopa County is the heart of the Phoenix metropolitan area and the fourth-most populous county in the United States, holding well over half of Arizona's population across Phoenix, Mesa, Chandler, Scottsdale, Gilbert, Glendale and Tempe. Year after year it posts some of the largest numeric population gains of any U.S. county, and its expanding semiconductor corridor, master-planned communities and sustained in-migration keep it among the most active real estate and development markets in the country.
