1. Start with Maricopa’s actual service area
The 2020–2024 ACS 5-year population estimate is 67,163, with a margin of error of 71. For attribution, the practical question is narrower: which parts of your service-area marketing produce inquiries that your firm can identify and evaluate?
Recommended approach
Define the geographic labels your firm will use before reviewing performance. Decide whether a matter is attributed to Maricopa, another Pinal County location, a broader Arizona area or an address outside the service area. Keep municipality, county, metropolitan area, household and individual distinctions separate. Use it to make sure your reporting categories describe the place you actually serve.
