1. Start with Montgomery’s actual service area
Montgomery is recorded by the U.S. Census Bureau as a municipality in Illinois associated with Kane County and Kendall County. Its 2020–2024 ACS five-year population estimate is 21,515, with a margin of error of 487. That figure is context for defining the place you serve; it does not establish legal demand, search activity, competition, lead volume or revenue. For attribution, the practical question is narrower: which geographic references appear in your inquiries, landing pages, intake records and matter outcomes?
Recommended approach
Use the consultation to define the geographic labels your firm already uses, including Montgomery and the relevant county relationships. Then decide whether attribution should distinguish a Montgomery page, a county page, a broader Illinois page, a referral, or a returning visitor. Do not treat the population estimate as a forecast. Treat it as a boundary-setting fact that helps prevent your reporting from mixing a municipality with a county or a wider metropolitan area.
