1. Start with Buffalo Grove’s actual service geography
Buffalo Grove is recorded as a municipality in Illinois, with relationships to Cook County and Lake County. The 2020–2024 ACS five-year population estimate is 42,891, with a margin of error of 67. A useful review asks whether a lead came from a Buffalo Grove page, another service location, a referral or a different path—and whether the matter belongs to the firm’s intended coverage area.
Recommended approach
Define the geographic fields and service-area rules your team will use when reviewing a lead. Keep Buffalo Grove, Cook County, Lake County and broader Illinois coverage distinct.
