Start with the geography your firm actually serves
Barrington village is a municipality in Illinois associated with Cook County and Lake County. The 2020–2024 ACS five-year estimate records 11,077 residents, with a margin of error of 644. That figure describes the municipality’s population; it does not establish legal demand, search volume, competition, lead volume or revenue. For Reputation & Reviews, the useful question is narrower: which clients and matters may reasonably be included in your firm’s review process, and which geographic areas should appear when you assess your public profile? A firm serving Barrington alone should not automatically treat both counties as its market. A firm serving a broader area should document that coverage rather than infer it from the town’s population.
Recommended approach
Map the firm’s actual service area by matter type and client eligibility. During the review, compare your Google Business Profile and public reviews against the locations you intentionally serve, then decide whether a Barrington-focused evaluation, a Cook County and Lake County evaluation, or a broader Illinois review is appropriate.
