1. Start with the Streator service area your site must serve
Streator is recorded as a municipality in Illinois. The 2020–2024 ACS five-year estimate lists 12,330 residents, with a margin of error of 524, and records relationships with LaSalle County and Livingston County. That information describes the city and its county relationships; it does not establish search demand, competition, legal need, leads or revenue. For hosting, the useful question is narrower: can your current website reliably serve the geographic pages and intake paths your firm has decided to maintain for Streator, LaSalle County, Livingston County or other areas?
Recommended approach
Bring a current inventory of the pages, forms, phone links and third-party services that matter to your Streator practice. Decide which geographic scope is intentional before discussing infrastructure. Do not use the population estimate as a forecast of traffic. Instead, use it to keep the service-area definition precise and test the site itself under the conditions your firm considers important.
