1. Start with the geographic record, not a demand assumption
The U.S. Census Bureau records Williston as a municipality in Williams County and gives the city a 2020–2024 ACS 5-year population estimate of 28,056, with a margin of error of 24.
Recommended approach
Define which inquiries count as Williston matters, which may come from elsewhere in Williams County, and which service areas should be separated in reporting. Ask whether your current records can distinguish location, case type, source and qualification without asking staff to guess.
