Filings from Oak Brook, IL fall inside the federal statistical area CHICAGO-NAPERVILLE-ELGIN, IL-IN-WI. That area is larger than this city — it spans several cities and, where the name says so, more than one state. Everything on this page is computed from filings whose worksite city is Oak Brook itself, so the numbers above are city figures, not area figures.
Ranked by number of filings, not by pay and not by quality. This is not a “best employers” list. Employers with fewer than 10 filings here show the count only. 227 employers in total filed for a worksite in Oak Brook; the 25 above are those with the most filings. Those with at least 10 certified filings have their own page; the rest are counted here but do not.

We build a page for a city once it has at least 50 certified filings — 2,578 cities qualify, and 2,298 of those also clear our content threshold and are listed in the city index. Below the filing threshold we do not publish a median, because a median from a small number of filings reads like a market rate and is not one. Those filings are still counted on their employer's page.
