You may have some hypotheses about how work affects the health of the U.S. population, but collecting data from a nationally representative sample is expensive and time-consuming. What if there was free data available at your fingertips? You’re in luck!
NIOSH sponsored an Occupational Health Supplement (OHS) to the 2010 National Health Interview Survey (NHIS), and the data is publicly available. See the NIOSH Topic Page for more information. Over 17 thousand current and recent U.S. workers supplied information on their industry, occupation, and workplace health conditions and exposures.
