Changes in Labor Force Participation in the United States
回顾了20世纪下半叶美国劳动力参与率的社会和人口趋势，分析了2000年代的变化如何偏离过去趋势，并探讨了未来影响。
The labor force participation rate in the United States increased almost continuously for two-and-a-half decades after the mid-1960s, pausing only briefly during economic downturns. The pace of growth slowed considerably during the 1990s, however, and after reaching a record high of 67.3 percent in the first quarter of 2000, participation had declined by 1.5 percentage points by 2005. This paper reviews the social and demographic trends that contributed to the movements in the labor force participation rate in the second half of the twentieth century. It also examines the manner in which developments in the 2000s reflect a break from past trends and considers implications for the future.
