1. Set the geographic boundary before judging performance
Derby is recorded by the U.S. Census Bureau as a municipality in Sedgwick County, Kansas. Its 2020–2024 ACS 5-year population estimate is 26,062, with a margin of error of 38. That is geographic and population context—not evidence of legal demand, competition, search volume, leads or revenue. For an ROI Dashboard review, the important decision is how your firm will distinguish Derby activity from activity elsewhere in Sedgwick County, Kansas or any broader market it serves. Ask which city, county and statewide targets appear in the reporting, and whether a location label means a search target, a caller’s stated location or another definition.
Recommended approach
Bring a written geographic policy to the consultation. Decide which Derby and Sedgwick County activity should be reviewed separately, which wider Kansas activity belongs in the same view, and which locations should not be combined. Do not treat the Derby population estimate as a forecast of cases or return.
