1. Separate Barrington geography from marketing evidence
The U.S. Census Bureau records Barrington as a municipality with a 2020–2024 ACS five-year population estimate of 11,077 and a margin of error of 644. The record identifies Cook County and Lake County relationships. Those facts describe the place; they do not show how many people search for a lawyer, which matters are available, how many inquiries your firm receives, or which channel produces signed cases. A useful attribution review should preserve those distinctions.
Recommended approach
Ask whether your current records distinguish service area, inquiry location, practice area and source. Review those fields together before reallocating marketing budget. Keep Barrington, the two recorded counties and any broader Illinois service territory as separate geographic questions.
