Nearly 1 in 5 healthcare workers in the U.S. is a registered nurse, according to May 2025 data from the Bureau of Labor Statistics. RNs represent about 19% of the nation’s healthcare practitioner and healthcare support workforce, according to BLS data.
Below are 41 hospital occupations ranked by their share of the healthcare workforce, based on BLS Occupational Employment and Wage Statistics data released May 15.
Editor’s note: Percentages reflect each occupation’s share of total combined employment in healthcare practitioner and technical occupations and healthcare support occupations (17.7 million workers nationally), per May 2025 BLS Occupational Employment and Wage Statistics data. The figure in parentheses is each occupation’s total national employment across all industries. For occupations not classified by BLS as healthcare roles — including security guards, housekeeping cleaners, cooks and chaplains — hospital-specific employment was used in place of total national employment to calculate the percentage. All figures exclude self-employed workers. The list is not exhaustive.
