1. Start with the geographic question your records can actually answer
The U.S. Census Bureau records Nashua as a municipality in Hillsborough County. Its 2020–2024 ACS five-year population estimate is 91,294, with a margin of error of 68. That is context about the city, not evidence of legal demand, search volume, competition, lead volume or revenue. It should not determine a marketing budget by itself. For attribution, the practical question is narrower: when your firm receives an inquiry associated with Nashua or Hillsborough County, can you identify the path that led to it and the matter outcome?
Recommended approach
Define the geographic fields your firm genuinely needs before reviewing attribution. Keep Nashua, Hillsborough County and any broader service area distinct in reporting. Decide whether the relevant record is a household, an individual, an inquiry, a consultation or a signed matter; these are not interchangeable. Then review whether a source report can preserve that distinction instead of treating every local contact as the same type of opportunity.
