Start with the geography your firm actually serves
Foster City is recorded as a municipality in San Mateo County. The 2020–2024 ACS 5-year estimate records 32,792 residents, with a margin of error of 53. That is location context, not evidence of legal demand, competition, review volume or likely revenue. For reputation work, the more useful question is whether your Google Business Profile and review program represent the area in which you accept and serve matters. A firm may want Foster City alone, Foster City plus other San Mateo County communities, or a broader California footprint. Those are different decisions.
Recommended approach
Bring a precise service-area description to the consultation. Ask Bosseo to assess whether review messaging, profile information and reporting should be organized around Foster City, San Mateo County or another geography your firm can substantiate. Do not use the population estimate as a forecast.
