1. Start with Wellington’s actual service area
The 2020–2024 ACS five-year population estimate is 11,798, with a margin of error of 21. For attribution, the useful question is narrower: which geographic labels, service pages, referrals, and response paths does your firm actually use when serving people in Wellington and elsewhere in Larimer County?
Recommended approach
Before implementation, define the locations and matter types that should appear in your reporting. Keep Wellington, Larimer County, Colorado, and any broader service area distinct. This local distinction changes the measurement plan: the firm can compare the journeys associated with its chosen service areas instead of treating every Colorado visit as equivalent.
