In the private nonfarm business sector, multifactor productivity—output per combined units of labor and capital inputs—rose 1.8 percent in 2005. This was lower than the 2.6-percent increase in 2004.
Output increased 3.9 percent in 2005, and the combined inputs of capital and labor increased 2.0 percent.
Labor input grew 1.8 percent in 2005. Capital services grew 2.4 percent. Within capital services, equipment was the fastest growing component. The increase in equipment in 2005 was largely due to capital services of information processing equipment and software rising by 6.7 percent.
