Start with Old Jamestown’s actual service area
The U.S. Census Bureau records Old Jamestown as a census-designated place in St. Louis County, Missouri. Its 2020–2024 American Community Survey five-year population estimate is 20,651, with a margin of error of 1,626. That figure describes the population estimate; it does not establish legal demand, call volume, competition, language preference, lead volume or revenue. It does, however, make geographic precision important when you review your phone records. Separate calls from Old Jamestown, the rest of St. Louis County and any broader service area rather than treating every Missouri caller as part of one local segment.
Recommended approach
Use Old Jamestown and St. Louis County as reporting labels only if your intake records can support them. Review a defined period of calls and ask how often location is captured, whether the firm serves the caller’s jurisdiction and whether a callback owner is assigned. Do not use the Census estimate as a forecast.
