ECO 372Ta. The population older than 16 can be calculated by subtracting the number of children under 16 and the retirees from the total population. So, the population older than 16 is 35.4 - 6.7 - 6.6 = 22.1 million. b. The size of the labor force is the sum of employed and unemployed individuals. Therefore, the labor force is 18.5 + 1.9 = 20.4 million. c. The labor force participation rate can be calculated by dividing the labor force by the population older than 16 and multiplying by 100. So, the labor force participation rate is (20.4/22.1) x 100 = 92.3%
