1. Define Oak Brook reporting before you inspect the numbers
A location label can hide an important distinction. Oak Brook is recorded as a municipality, and its county relationships are Cook County and DuPage County. Oak Brook, either county, the wider metropolitan area, Illinois, households and individuals are not interchangeable reporting categories. The Census population estimate describes the municipality; it does not establish legal demand, search volume, competition, calls, cases or revenue. Your dashboard review should therefore begin with geography rules. Ask which city labels are tracked, whether county labels are separate, and how a call or form is assigned when a prospective client mentions a service area rather than a precise address.
Recommended approach
Bring a written location definition to the consultation. Decide whether Oak Brook should be a standalone city value, how Cook County and DuPage County should appear, and which broader Illinois or metropolitan views are appropriate for management decisions. Do not treat the population estimate as a forecast. Treat it as a boundary and eligibility reference when deciding what the dashboard should display.
