Final answer:
The size of the labor force is 372,155,202. The number of unemployed is 27,913,890. The size of the population is 442,375,002.
Step-by-step explanation:
The size of the labor force can be calculated by dividing the number of employed people by the labor force participation rate. So, the size of the labor force is 312,814,747 / 0.84 = 372,155,202 (rounded to the nearest whole number).
The number of unemployed can be calculated by multiplying the size of the labor force by the unemployment rate. So, the number of unemployed is 372,155,202 * 0.075 = 27,913,890 (rounded to the nearest whole number).
The size of the population can be calculated by dividing the size of the labor force by the labor force participation rate. So, the size of the population is 372,155,202 / 0.84 = 442,375,002 (rounded to the nearest whole number).
