Among the 20 largest (by employment) service-providing and mining industries, drinking places (alcoholic beverages) recorded the largest increase in labor productivity (output per hour) in 2009, as hours fell more than twice as fast as output. Support activities for mining—in which both output and hours fell by double digits over the year—recorded the largest productivity decline.
From 2008 to 2009, output per hour increased in 21 of the 47 detailed service-providing industries and in 2 of the 5 detailed mining industries studied. Although productivity changes varied widely among the service-providing and mining industries, almost all of the increases in productivity involved declines in hours.
Productivity rose in the overall mining sector and in the oil and gas extraction and metal ore mining industries in 2009, but declined in coal mining, in nonmetallic mineral mining and quarrying, and in support activities for mining. Hours fell in all of the mining industries.
