The labor participation rate refers to the labor force as a proportion of the civilian population aged 15 years & over, and is also the percentage of the civilian population aged 15 years & over participating in labor. Because the labor force includes both employed and unemployed persons, any increases or decreases in the number of employed or unemployed persons will affect the labor participation rate. The labor participation rate is calculated using the following method:Labor participation rate (%) = labor force/civilian population aged 15 years & over *100%
