DEFINITION of 'Participation Rate'. A measure of the active portion of an economy's labor force. The participation rate refers to the number of people who are either employed or are actively looking for work.he number of people who are no longer actively searching for work would not be included in the participation rate. During an economic recession, many workers often get discouraged and stop looking for employment, as a result, the participation rate decreases.
The labor force participation rate is defined as the percentage of the civilian noninstitutional population 16 and over working or looking for work. It is largely determined by demography, most notably the share of the adult population of prime working age, typically 25 to 54.he most recent U.S. recession and recovery have been accompanied by a sharp decline in the labor force participation rate. The largest declines have occurred in states with the largest job losses. This suggests that some of the recent drop in the national labor force participation rate could be cyclical.
