Millennials are almost twice as likely to be registered nurses as baby boomers, according to a new study in the journal HealthAffairs. However, growth in the registered nurse workforce will slow to 1.3% between 2015 and 2030 from a rate of 2.5% between 2000 and 2015.

The findings assuage fears of a nursing shortage brought on by retirement of baby boomers, one of the report’s authors, Peter Buerhaus, told Anne Cantrell of Montana State University News Service. Buerhaus is director of the university’s Center for Interdisciplinary Health Worker Studies.

“This fear no longer appears to be justified, as the millennial generation is well on its way to replacing the baby boomers and supplying an additional 1 million RNs between now and 2030,” Buerhaus told the news service. Although there is the caveat that there will be slower growth through 2030, and there could be localized shortages of nurses in the US.

The study was by researchers at Montana State University in Bozeman, Mont., and Dartmouth College in Hanover, NH.
