How should we collect data on the nursing workforce?

Researchers who study the nursing workforce use data about nurses and data about nursing jobs. Different approaches - sample surveys and relicensure surveys - used to collect data on RNs, and the benefits and weaknesses of these approaches, are reviewed. Predicting the future supply of nurses is more complex than estimating the current supply, as factors that affect future supply must be considered. Simple forecasts can be created with relatively few variables, which could be collected through relicensure surveys. However, more detailed assessments of potential retirement patterns, changing family norms regarding child-care and household work, and movements into higher education require the rich data more often found in sample surveys.
