Changing Workforce Demographics and Workplace Injury Frequency

The Modern Worker and On-the-Job Injuries: How Changing Employee Demographics Affect Claims Frequency

The shape of the workplace is changing.

The number of employees 55 and older has doubled since 2000. Women make up more than half of labor force growth. Service sector jobs are near record highs.

How do these shifts in the employment pool correlate to injury claims?

In this paper, NCCI explores the relationship between age, gender, sector, and frequency over the last decade. How do recent changes in frequency differ across demographic groups? And how do changing demographics affect workers compensation claim frequency?


Among the key findings:

  • Younger workers are getting injured less often than their older peers, a major shift in relative rates
  • The gender gap in frequency is narrower due to injury rates falling faster for men than for women
  • Frequency decline is driven mainly by lower incidence rates for all workers, not demographic shifts
  • Workforce aging has had almost no effect on frequency decline
