1. Start with Park Ridge’s actual geographic boundary
Park Ridge is a municipality in Cook County, Illinois. The 2020–2024 American Community Survey 5-year estimate records 38,667 residents, with a margin of error of 540. That figure establishes the place and its population estimate; it does not establish legal demand, search volume, lead volume, competition or revenue. Attribution should therefore begin with the geographic choices your firm actually makes: Park Ridge alone, Cook County, the Chicago metropolitan area, or a wider Illinois service area. Mixing those levels in one report can make a local page appear to have produced an outcome that came from a broader market.
Recommended approach
Decide which geographic labels matter to your intake and marketing decisions before reviewing attribution. Keep Park Ridge, Cook County, metropolitan areas and Illinois as separate reporting questions rather than treating the population estimate as a demand forecast.
