How Illinois ranks

A state's raw firm count and its disciplinary clean-record rate measure two different things, and they do not always move together. A jurisdiction can host a large number of broker-dealer firms simply because it is a major financial hub, while a smaller state with far fewer registered firms can post a cleaner disciplinary record in relative terms, or vice versa. Comparing both rankings side by side, rather than looking at either figure in isolation, gives a fuller picture of what is actually happening on the ground in a given state.

By firm count, Illinois is #4 of 56 states and territories. By clean-record rate (Grade A share, among the 33 states with at least 10 registered firms, a floor that keeps a state with only a handful of firms from swinging to an extreme rate on a tiny sample), it ranks #23 of 33. These ranks diverge notably -- a larger firm footprint here does not translate into a proportionally cleaner record. Neither ranking implies wrongdoing on its own; always review an individual firm's own size-normalized grade before drawing a conclusion about it specifically.
