The people who are not counted as part of the official measure of the labor force in the United States include:
(i) Individuals under the age of 16, as they are not considered old enough to work and participate in the labor force.
(ii) Retirees, as they are not actively seeking employment or working.
(iii) Institutionalized people, such as those in prisons or mental health facilities, as they are not available for employment.
(iv) Those who are not working but getting job training, as they are not considered unemployed unless they are actively seeking employment and available to work.
