The labor force participation rate is the percentage of the adult, noninstitutionalized, nonmilitary population that is either employed or actively seeking employment.
To calculate the size of the labor force, we can use the following formula:
Labor force = Adult, noninstitutionalized, nonmilitary population x Labor force participation rate
Labor force = 266.272 thousand x 0.626
Labor force = 166.805672 thousand
Therefore, the size of the labor force is approximately 166,806 thousand.
