1. Start with Waukegan’s actual geographic role
The 2020–2024 ACS five-year estimate records 89,076 residents, with a margin of error of 423. For your firm, the useful question is narrower: do you serve Waukegan, and does it belong in the footprint for each service you want to promote?
Recommended approach
Separate Waukegan from the rest of Lake County in your planning. List the communities you genuinely serve, identify any service-area limits, and decide whether the first scope should cover Waukegan alone, selected Lake County communities, or a wider Illinois footprint.
