Start with the geography your firm actually serves
The U.S. Census Bureau records Frankfort village as a municipality in Illinois, with relationships to Cook County and Will County. Its 2020–2024 ACS 5-year population estimate is 20,651, with a margin of error of 66. That is a useful boundary for discussing Frankfort, but it does not establish legal demand, search volume, competition, lead volume or case value. It also does not show whether an inquiry came from a Frankfort resident, a county resident, a referral source or someone seeking a firm that serves a wider area.
Recommended approach
Before reviewing attribution, define the geographic labels your intake team uses. Keep Frankfort, Cook County, Will County and any metropolitan-area or statewide service area separate. Then ask whether the journey record identifies the page, channel and case type that preceded each inquiry. This prevents a municipal population figure from becoming a substitute for actual source and outcome data.
