Should I negotiate based on the BLS median for Illinois?

BLS OES releases a new May reference set roughly each spring; we re-run the ETL pipeline within two weeks of release. BEA RPP refreshes annually. The last-synced timestamp at the top of this page reflects the most recent build.

DSO / corporate dental vs private practice hygienist pay in Illinois?

BLS does not split DSO (dental service organization) from solo private-practice employment. In Illinois, DSO chains (Aspen, Heartland, Pacific Dental, Smile Brands) have historically led on starting pay and benefits at the cost of higher production quotas and tighter scheduling. Solo private practice in Illinois pays similarly on the headline rate but typically offers more autonomy on instruments, recare intervals, and patient mix. Per-day production-bonus structures in DSO settings can push experienced hygienist comp 10-20% above BLS median.
