This information is from the BLS Current Employment Statistics program. For each industry, average weekly hours is computed by dividing the sum of reported paid hours by the total number of production or nonsupervisory workers in the industry. Changes in average weekly hours in an industry can be due to various reasons; for example, there could be a shift in an industry to employing more part-time workers.
