Health Workforce Data

National Sample Survey of Registered Nurses (NSSRN) Data

Since the 1970s, the NSSRN has been the primary source of data on the nursing workforce: the largest group of health care professionals. View the recently released survey findings.

The National Center for Health Workforce Analysis (NCHWA) assesses health surveys and data on the supply, use, access, need, and demand for health workers.

To help with your analysis and research, we gathered resources by the following types:

Data Policy

Standard Occupational Classification (SOC)

The SOC system—a federal taxonomy—classifies workers into occupational categories. There are 840 detailed occupations in all.

We work with the Office of Management and Budget (OMB) and the Bureau of Labor Statistics to ensure that the Standard Occupational Classification (SOC) system includes current complexities of occupations in the health sector.

Federal statistical agencies must use the SOC to collect, calculate and distribute consistent data on the U.S. workforce.

The SOC Policy Committee revises the catalog approximately every 10 years.

Minimum Data Sets

A Minimum Data Set provides basic, uniform, and consistent information on the health workforce.

Minimum Data Sets facilitate the establishment of national databases with consistent core data elements covering demographic, educational, credentialing, and practice characteristics of health professionals.
