The American Association of Colleges of Nursing (AACN) provides a fact sheet on the nursing shortage. The fact sheet cites estimates that the supply of RNs went down by 100,000 from 2020 to 2021. It also provides references to find RN shortages in each state through 2030. Recent studies of nursing enrollment show that U.S. nursing schools turned away nearly 92,000 qualified applicants in 2021, due to faculty shortages, clinical sites, budget constraints and the like. Fact sheet updated October 2022.
