1. Define the geographic view before reading the numbers
The 2020–2024 ACS five-year population estimate is 9,505, with a margin of error of 52. Your dashboard review should therefore distinguish Grinnell from Poweshiek County rather than treating every location label as interchangeable. Ask which service-and-city targets are being tracked, which calls are associated with each target, and whether a city or county label reflects the person’s location, the page visited or another attribution rule.
Recommended approach
Begin with a written geographic definition. Decide whether the firm wants to review Grinnell only, Poweshiek County, or both, and keep those views separate. Use it only to explain why geographic labels need careful interpretation.
