The significance of age on job injury frequency has diminished, suggesting that age may not play an important role in future frequency trends for workers' compensation, a new study has found.

The findings were reported by the Boca Raton, Fla.-based National Council on Compensation Insurance, which reported that on average, younger workers have more frequent comp injury claims, while older workers get hurt less but require more expensive care when they do.

NCCI's report–"Age as a Driver of Frequency and Severity"–follows NCCI research in 2005 that found workers' comp medical cost claims that develop into costlier lost-time claims with indemnity payments most often involve older employees.
