People who are considered unemployed are those who are actively seeking work but are unable to find a job. This includes people who have lost their job, people who have recently entered the labor force and are looking for work, and people who are returning to the labor force after a period of absence. People who are not actively seeking work, such as those who have given up looking for a job, are not considered unemployed. Additionally, people who are employed part-time but would like to work full-time are considered underemployed, but they are not counted as unemployed.
