National Occupational Mortality Surveillance (NOMS)

National Occupational Mortality Surveillance (NOMS)

NIOSH National Occupational Mortality Surveillance (NOMS) is a partnership between NIOSH, NCHS and vital statistics jurisdictions that provides periodic surveillance of work-related mortality among US workers. The program protects workers by evaluating the size and extent of disease mortality in association with occupation and industry settings. NOMS does this by providing data to identify new risks or confirm existing risks for occupational disease mortality that can point to opportunities for prevention and further study. For more information on data and PMRs see National Occupational Mortality Surveillance | NOMS | NIOSH | CDC or email noms@cdc.gov

Available Charts

The following data set is available from NOMS to chart. Select the "Create Charts" button to access the charting tool.

Cause of Death (NOMS 2020-2023)
National Occupational Mortality Surveillance (NOMS)

These charts include age-adjusted Proportionate Mortality Ratios (PMRs) and age-adjusted Rates.

  • PMRs are proportion of deaths due to a specific cause for workers in one industry/occupation group divided by the proportion of deaths due to that cause in all workers multiplied by 100.
  • Rates are the number of deaths in an industry/occupation group divided by the population of people working in that industry/occupation multiplied by 100,000. The denominator data used to calculate the rates are from the Current Population Survey

You can chart Cause of Death groupings by industry/occupation for both PMRs and Rates. PMRs are also available by age, sex, race and Hispanic ethnicity although there may be few deaths in some categories. Data include all decedents 18-90 years of age for

  • 2020 (46 states and NYC),
  • 2021 (49 states and NYC), and
  • 2022 and after (50 states and the District of Columbia),

who had usual industry and/or occupation information available on their death certificate.

Data and documentation used in these charts are from the Public Use Data available from the NCHS Vital Statistics Data website.
