Final answer:
Approximately 62.87% of the population in the United States over the age of 16 is in the labor force.
Step-by-step explanation:
To calculate the percentage of the population in the United States over the age of 16 that is in the labor force, you need to divide the number of people in the labor force by the total adult population and multiply by 100. According to the given data, there are 159.716 million people in the labor force and 254.082 million in the total adult population.
Dividing 159.716 million by 254.082 million gives us 0.6287. Multiplying this by 100 gives us a percentage of approximately 62.87%. Therefore, approximately 62.87% of the population in the United States over the age of 16 is in the labor force.
