1. Start with the geography your firm actually serves
The U.S. Census Bureau records Manhattan as a municipality in Will County, Illinois. Its 2020–2024 ACS 5-year population estimate is 11,026, with a margin of error of 463. That is population context only; it does not establish legal demand, competition, search volume, leads, cases or revenue. For reputation work, the useful question is narrower: which locations should a prospective client associate with your firm, and which Google Business Profile should represent that service area? A firm serving Manhattan residents may also serve clients elsewhere in Will County or across Illinois, but those are different geographic claims.
Recommended approach
List the municipalities, county areas and broader Illinois service regions you are prepared to support. Then decide whether the profile, review-request language and reporting should emphasize Manhattan, Will County or a wider service area. Do not use the village population as a forecast.
