1. Define the geography before you read the numbers
McNair is a census-designated place, and the cited Census record places it in Fairfax County. Those are different geographic descriptions: McNair is not the same thing as the county, the Commonwealth of Virginia or a metropolitan area. A dashboard view that combines them without clear labels can make a local result difficult to interpret. Population is useful context for deciding which geographic definitions deserve review, but it cannot tell you how many people search for legal services or how many matters a firm will receive.
Recommended approach
Ask for a geographic definition sheet before relying on a location total. It should identify whether a view refers to McNair, Fairfax County, Virginia or another service area, and whether a metric is assigned by keyword, page, caller information, form information or another stated rule. Review location naming in rankings, lead records and attribution separately; do not accept a single blended local number as an answer to every planning question.
