At the National Center for Health Workforce Analysis (NCHWA), we assess 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:
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.
Minimum Data Sets Created by National Boards, Councils, and Associations

Compedium of Federal Data Sources to Support Health Workforce Analysis
This compendium (PDF - 374 KB) provides a summary of 19 federal data sources that, while not established specifically to collect or present health workforce data, can be used to support health workforce analysis. The compendium helps you understand how to use these sources for health workforce analysis.
AHRF State/County Level Data Comps
The Area Health Resources Files (AHRF) contain health workforce data for every U.S. county, drawn from more than 50 sources. Included are data on:
- health care professions
- health professions training
- health facilities
- hospital utilization
- hospital expenditures
- population and economic statistics
- codes and classifications
Nursing Health Workforce Modeling Tool
The Nursing Health Workforce Modeling Tool helps you better understand the future supply of, and demand for, nurses at the national and state levels.
With the tool you can:
- examine how many registered nurses and licensed practical nurses exist as it relates to the services they provide,
- explore alternative scenarios by modifying key parameters such as graduation rates, and attrition and retirement rates of nurses that fit local conditions, and
- upload data into the model, and use the results as a planning tool for recruitment and retention of the future nursing workforce.
You must register and then create an account to access the tool.
National Sample Survey of Registered Nurses (NSSRN)
The data from the National Sample Survey of Registered Nurses (NSSRN) helps us evaluate trends and projections of the future supply of nursing resources.
The NSSRN samples and estimates the characteristics of registered nurses in the workforce. Registered nurses participating in the survey answer questions relating to their experience in the field of nursing.

National Sample Survey of Nurse Practitioners (NSSNP)
Nurse practitioners play a critical role in extending access to health care by providing a range of primary and specialty care services.
In 2012, we conducted the National Sample Survey of Nurse Practitioners (NSSNP) to provide accurate national estimates of the nurse practitioner workforce and to profile their education, certification and practice patterns.
Primary Care Service Areas (PCSAs) define service areas across the U.S. and are a useful tool for analyzing the distribution of health professionals, primary care services, and access to primary care.
