Start with the geographic record, not a demand assumption
Alsip is recorded as a municipality in Cook County, Illinois. The Census population estimate is useful for defining the market being discussed, but it cannot tell you how many people are searching for a lawyer, which practice areas they need or how many inquiries your firm should expect. It also should not be used to infer language preferences, competition or call volume. For an Alsip-serving firm, the practical attribution question is narrower: can you distinguish inquiries associated with Alsip from activity elsewhere in Cook County or the broader Illinois market, while preserving the actual source and outcome of each inquiry?
Recommended approach
Bring a clear geographic definition to the consultation. Decide whether you want to evaluate Alsip alone, Alsip alongside other Cook County communities, or a wider service area. Then compare that definition with the locations your intake team records and the locations represented in your marketing. Do not use the population estimate as a forecast.
