Where the changes are
Cook County alone accounts for 38.1% of every change on file for Illinois, and 2 counties are enough to reach half of everything we can place in a county. Concentration matters for anyone working a territory: a list that looks statewide is usually a handful of counties.
By county
Counties with their own page are linked. The rest are listed with their real counts and are included in every total above. They have too little volume to support a page that would only repeat this one.

Other states we measure
Which associations, and when
The change feed names the association behind each of these counts, the seats that moved and the date it was observed, and can email you when a new match appears in Illinois.
See what the change feed tracksHow these numbers are produced
- What a change is
- An observed difference between two snapshots of the public record: a director arriving, a director leaving, a title moving between seats, a president handing over, a registration status changing. One filing that replaces three directors counts as the changes it contains, not as one event.
- Where it comes from
- State corporate and regulatory filings that associations are required to make. Nothing here is surveyed, modelled or estimated. A change appears when a source publishes it, which is usually after the board itself changed, so these counts trail reality rather than predicting it.
- What an association count means
- The number of distinct associations with at least one observed change, not the number of associations in Illinois. A rate of changes per association is therefore an intensity measure across the affected set only.
- Why some counties have no page
- A county needs at least 25 observed changes before it gets its own page. Below that the county has nothing to say that this page does not say better. Its count is still listed here and still counted in every total.
- What is deliberately not here
- No association is named, no officer is named, and no individual contact information appears on these pages. They report how much and where. Which association, and when, is the paid change feed.
- Observed through
- The newest change counted on this page was observed on September 1, 2026. Figures describe what a source published on a given date, not a legal determination of who holds an office.
