NIOSH Data and Statistics Gateway

NIOSH Data and Statistics Gateway


Data are fundamental to worker safety and health research and surveillance conducted at NIOSH. The data produced and used by NIOSH can also benefit other researchers and practitioners as well as the general public. This NIOSH Data and Statistics page provides centralized access to select NIOSH data sets.

Research Data

Public use data sets from NIOSH research on a range of topics, including:

Advanced manufacturing (nanotechnology, 3d printers) Injury
Anthropometrics Musculoskeletal Disorders
Chronic disease Noise and hearing loss
Exposure assessment PFAS
Hazardous drugs in healthcare Pneumoconiosis
Immune and dermal disease Personal protective equipment (PPE)
Infectious disease (influenza, COVID-19, and other respiratory viruses) Reproductive health

Each data set also includes a detailed methodology and data dictionary.

Surveillance Data

Absenteeism in the Workplace
NIOSH monitors absences reported by full-time workers due specifically to their own illness, injury, or other medical issue.

Behavioral Risk Factor Surveillance System (BRFSS)
NIOSH developed the BRFSS Industry and Occupation optional module that states can choose to use.

Fatalities in the Oil & Gas Extraction Industry (FOG)
A national database that collects detailed information about worker fatalities in the U.S. oil and gas extraction industry.

Mining Data & Statistics
Mine and mine worker charts; tools for economic analyses; data tables and graphs for historical mine disasters; and downloadable data files.

National Occupational Mortality Surveillance (NOMS)
Federal-state partnership that monitors changes in cause of death by usual occupation or industry in the United States.

Noise and Occupational Hearing Loss Surveillance and Statistics
Through partnerships with audiometric (hearing test) service providers and others, NIOSH collects de-identified worker audiograms.

Occupational Respiratory Disease Surveillance
National statistics, state-based surveillance, and medical monitoring.

Worker Health Information from the National Health Interview Survey (NHIS)
Industry and occupation questions are part of a rotating core module that is included two out of every three years. In 2010 and 2015, NIOSH sponsored sets of work-related questions in the NHIS, called Occupational Health Supplements (OHSs).

Workers’ Compensation Dashboards
Summary dashboards of workers’ compensation data from Ohio and the U.S. overall.

Interactive Data Tools

NIOSH Worker Health Charts

Using worker health information gathered by NIOSH and the Bureau of Labor Statistics, here you can create your own charts to assess current rates, distribution, and trends in workplace injuries, illnesses and deaths.

Employed Labor Force (ELF) – Interactive tool for calculating employed labor force counts and FTE from the Bureau of Labor Statistics’ Current Population Survey

Firefighter Fatality Map – Interactive tool for exploration of firefighter fatalities with map, statistics, case listings, NIOSH investigation status, and access to fatality investigation reports

Work-related Injury Statistics Query System (Work-RISQS) – Interactive tool for exploration of nonfatal occupational injuries treated in emergency departments from the National Electronic Injury Surveillance System—Occupational Supplement (NEISS-Work).

Data Analysis Tools

NIOSH Industry and Occupation Computerized Coding System (NIOCCS)
NIOCCS is a free web application that converts industry and occupation text into standardized codes. Industry and occupation text are often collected on surveys, death certificates, and medical records. These descriptions need to be converted into a numeric code so that researchers can analyze their data

Analyze Industry and Occupation Data
Downloadable code for SAS, R, and EpiInfo7 to create industry or occupation categories.

Occupational Injury and Illness Classification System (OICCS)
Interactive display and search tool for Bureau of Labor Statistics OIICS coding system for nature of injury, body part, event, and source of injury.

Other Data Resources

Systems that provide information about NIOSH investigations, products, hazards, and a variety of tests and measurements.


  • Engineering and Physical Hazards Reports – NIOSH conducts research on engineering control solutions for reducing exposures to air contaminants and on physical hazards such as noise and musculoskeletal hazards. This database has reports from laboratory research, walkthrough (or preliminary) surveys, and in-depth field surveys.
  • Engineering Controls Reports – Central repository of current NIOSH information on engineering control technology, summarized from previously published NIOSH research findings
  • Fatality Assessment and Control Evaluations (FACE) Program – NIOSH FACE Program and State FACE Programs study fatal workplace injuries and prepare reports with recommendations to prevent similar deaths.
  • Fire Fighter Fatality Investigation and Prevention Program – Conducts independent investigations of firefighter line-of-duty deaths and recommends ways to prevent deaths and injuries.
  • Health Hazard Evaluations – Helps employees, unions, and employers learn whether health hazards are present at their workplace and recommends ways to reduce hazards and prevent work-related illness.


  • Emergency Response Safety and Health Database – Contains accurate and concise information on high-priority chemical, biological and radiological agents that could be encountered by personnel responding to a terrorist event.
  • International Chemical Safety Cards (WHO/IPCS/ILO) – Data sheets that provide essential safety and health information concisely. The ICSC project is a joint effort of the World Health Organization (WHO) and the International Labour Organization (ILO), with the cooperation of the European Commission.
  • Immediately Dangerous to Life and Health Values (IDLH) – Values developed by NIOSH that represent the concentration of a chemical in the air to which healthy adult workers could be exposed (if their respirators fail) without suffering permanent or escape-impairing health effects.
  • NIOSH Pocket Guide to Chemical Hazards (NPG) – Informs workers, employers, and occupational health professionals about workplace chemicals and their hazards. The NPG gives general industrial hygiene information for hundreds of chemicals/classes.
  • Occupational Health Guidelines for Chemical Hazards – Summarizes information on permissible exposure limits, chemical and physical properties, and health hazards.
  • Skin Notation Profiles – Hazard warnings used worldwide to alert workers and employers to the health risks of skin exposures to chemicals in the workplace
