This study used workers' compensation data to examine seasonal trends of compensable injuries among workers 14 to 24 years old during a 10-year period. These workers had higher rates of occupational injuries in major classes of industry (e.g., service, manufacturing, and agriculture) during summer and non-summer months. The overall rate of occupational injury was significantly higher for male workers than female workers in all age groups (p < .001). Young workers experienced occupational injuries within less than 3 hours of starting a shift. Among males, injury rates were highest in the manufacturing industry for those 14 to 18 years old and in the service industry for those 22 to 24 years old for both seasons. These results indicate that preventing injuries among young workers should be a primary concern of education and health and safety professionals and parents.
