1. Start with Mundelein’s actual service area
Mundelein village is a municipality in Lake County, Illinois. The 2020–2024 ACS 5-year population estimate for the village is 31,915, with a margin of error of 30. That figure describes the population of the municipality; it does not establish call demand, legal need, competition, language preference, or the number of prospective clients for your firm. It does, however, give you a precise boundary for a service-area conversation. You can decide whether callers from Mundelein, elsewhere in Lake County, or outside your normal geography should follow the same intake route.
Recommended approach
Bring your preferred geographic rules to the review. Decide whether location is an early screening question, a later attorney-review item, or simply part of the caller record. Do not use population as a substitute for your own phone records. Compare the places your firm actually serves with the places it declines, and make sure the answering path reflects that distinction.
