1. Start with the Fort Collins–Larimer County relationship
Fort Collins is recorded as a municipality in Larimer County. The 2020–2024 American Community Survey five-year estimate records 170,229 residents, with a margin of error of 96. That is geographic eligibility information, not evidence of search demand, competition, leads, cases, or revenue. For your firm, the useful decision is whether Fort Collins and the rest of Larimer County belong in the service area you can responsibly describe and serve. A city page should not imply that you maintain an office there, handle every matter there, or serve the entire county unless those statements are true.
Recommended approach
Define the footprint in operational terms. Confirm whether you want Fort Collins only, Fort Collins plus other Larimer County communities, or a wider Colorado geography. Then list the locations where your firm genuinely accepts matters and can explain relevant service information. Use the Census geography to keep the location relationship precise; do not use the population estimate as a forecast.
