Adult population = 247,947,000 Labor force size = 155,922,000 Labor force participation = 93.8% Unemployment rate = 6.2% The adult population is the sum of employed, unemployed, and not in the labor force. So 146,305,000 + 9,617,000 + 92,025,000 = 247,947,000 The size of the labor force is the sum of those who are employed and unemployed. So 146,305,000 + 9,617,000 = 155,922,000 The labor force participation rate is the percentage of the labor force that's employed. So 146,305,000 / 155,922,000 = 0.938321725 = 93.8% The unemployment rate is the percentage of the labor force that's unemployed. So 9,617,000 / 155,922,000 = 0.061678275 = 6.2%
