The unemployment rate in the United States has been declining since the Great Recession ended in mid-2009.1 This decline has been partly due to discouraged workers leaving the labor force, as illustrated by the decrease in the labor force participation rate in the figure below.2
However, the labor force participation rate has started to increase after trending downward since the end of the recession. It rose from 62.4 percent in September to 63 percent in March before settling at 62.8 percent in April. During this period, the unemployment rate continued decreasing, reaching 5 percent in April.
A closer look at the labor force participation rate is important to understand what is behind this trend. To do that, we decomposed labor force participation by gender, age and education levels for the period beginning in September.
Several patterns emerged from these figures. First, we observed that the increase in female participation led to the increase in the labor force participation rate before November. However, the male participation rate has been increasing at a faster pace since then.
Second, the labor force participation rate has risen across all age categories:
The most interesting patterns arose when we looked at labor force participation by levels of education. We observed that the lowest education group increased its participation rate the most, from 44.8 percent to 46.1 percent. The highest education group, however, saw an overall slight decrease in its participation rate. For other education groups, there was not a clear trend.
Based on the above decompositions, we concluded that the recent increase in the labor force participation that we observed has been mainly driven by males and the lowest education workers.
 The unemployment rate is the fraction of the labor force that is unemployed (jobless, actively searching for a job and available to take one). The labor force is comprised of employed and unemployed people in the working age population.
