1. Start with the Chatham service area, not a guessed lead forecast
The 2020–2024 ACS 5-year population estimate is 14,639, with a margin of error of 489. Identify whether your firm serves Chatham alone, Sangamon County more broadly, or another defined area, then assign inquiries according to your actual practice rules.
Recommended approach
Use Chatham and Sangamon County as the geographic boundary for an intake discussion, not as a proxy for pipeline size. Bring your current sources, matter categories and ownership rules to the consultation so the proposed response paths reflect the clients you actually accept.
