How this page is built
BLS OEWS May 2025 state estimates for Illinois and national estimates for SOC 29-1126 (Respiratory Therapists). The pay ladder compares the same five published percentiles; the difference column is the local value minus the U.S. value, divided by the U.S. value. Ranks compare published state medians across the 50 states and DC. Employment counts people working in the occupation (excluding the self-employed), not job openings. BLS publishes sampling error for these estimates: the employment estimate has a relative standard error of 5.3%. Lower is more precise; BLS does not publish a standard error for the median itself.
