Adjusted figures divide each state’s median by its 2024 regional price parity from the Bureau of Economic Analysis (U.S. = 100), the latest available. “≥ $239,200” means BLS reports the value only as $239,200 a year ($115.00 an hour) or more; those rows are placed at that lower bound and cannot be adjusted for prices. Dashes mean BLS did not publish an estimate.
