1. Start with the geography your firm actually serves
The U.S. Census Bureau records Yankton city as a municipality in Yankton County, South Dakota, with a 2020–2024 ACS five-year population estimate of 15,540 and a margin of error of 39. That is geographic and population context only. It does not establish legal demand, competition, search volume, call volume or revenue. Your attribution review should therefore separate a person’s location from the source and quality of the inquiry. A visitor may be in Yankton city, elsewhere in Yankton County or outside the area your firm accepts. Those distinctions matter when you judge a page, channel or campaign.
Recommended approach
Define the service geography and matter types that count before reviewing results. Then ask whether each recorded inquiry falls inside your accepted area and practice scope. Do not use the population figure as a forecast. Use it only to keep the local question precise: which journeys from people you can serve become qualified inquiries?
