Top Work-related Injury Causes

Detailed nonfatal data over 2023-2024

The U.S. Bureau of Labor Statistics (BLS) has transitioned from an annual to a biennial (every two years) publication schedule.  The final publication of a single year of cases involving days away from work estimates was for reference year 2020. The most recent BLS detailed data now cover 2023 and 2024 for Days Away from Work (DAFW)Days of Job Transfer or Restriction (DJTR), and Days Away from Work, Job Restriction, or Transfer (DART) cases.

New event categories starting in 2023

The BLS has updated the Occupational Injury and Illness Classification System starting with the 2023 data year. The update includes changes to how injury and illness events are classified. This change is considered a data break, therefore, comparing counts to previous years should be done with caution. Currently, 2024 fatality data and 2023-2024 nonfatal data are using the new classification categories.

Over 2023-2024, contact incidents had the most DAFW cases at 499,270, closely followed by overexertion injuries with 492,140 cases, and falls, slips, trips with 479,480 cases. Looking at the broader set of DART cases, overexertion incidents was the leading injury event, followed by contact incidents, and falls, slips, and trips.

Notably, with the continued decrease in reported COVID-19 illness cases, the exposure to harmful substances or environments category dropped from the leading injury or illness event in 2021-2022 resulting in days away from work to the fourth most prevalent event category in 2023-2024.
