The Health Resources and Services Administration (HRSA) has released data collected from the National Sample Survey of Registered Nurses (NSSRN). This survey data was last released in 2008 and is the principal source of information on the nursing workforce: the largest group of health care professionals.
The data from these periodic surveys provide the basis for evaluating trends and projecting the future supply of nurses. HRSA programs use the information collected to assess nursing requirements at the state and national level.
Registered nurses participating in the survey answer questions relating to their profession as well as their experience in the field of nursing.
