1. Start with the correct geographic boundary
The 2020–2024 ACS five-year population estimate is 12,152, with a margin of error of 29. A firm may serve Palos Heights, other Cook County communities, or a wider Illinois footprint; those are separate choices.
Recommended approach
Treat Palos Heights as one city-level location and Cook County as a possible county-level boundary. In a consultation, review the cities and counties the firm actually serves, the legal services it wants to promote, and whether statewide coverage is appropriate.
