Suppose that the U.S. noninstitutional adult population is 230 million and the labor force participation rate is 67 percent. What would be the size of the U.S. labor force?
The civilian labor force in a country is made up of all of the adults who are not in prison or in the military and who are either working or are technically unemployed. The civilian labor force does not include retired people as they no longer want jobs. It also does not include people who choose not to work for money (stay at home parents are the most common such group).
In this scenario, the total noninstitutional population is 230 million. 67% of them are in the labor force. To find the size of the labor force we must calculate
230*.67 = 154.1
Therefore, the labor force is made up of 154.1 million people.
