Start with the geographic question, not the population number
Marvin is recorded as a municipality in Union County, North Carolina. Your firm may serve Marvin alone, Union County more broadly or additional locations, but those are different geographic choices. A village population estimate cannot tell you how many people search for a lawyer, how many firms compete for a matter or whether a review campaign will produce a particular number of calls. It can, however, help keep the review discussion precise: identify whether your Google Business Profile and public responses should speak to a Marvin audience, a countywide practice or a wider North Carolina service area.
Recommended approach
Map the places your firm actually serves before selecting review language or interpreting results. Separate the location attached to the office profile from the locations accepted for representation. Review performance by service area and matter type rather than treating every inquiry associated with North Carolina as equivalent.
