Which of the following is included in the unemployment rate?

The unemployment rate is a measure that reflects the percentage of the labor force that is jobless and actively seeking employment. In this context, the correct answer focuses on individuals who have made efforts to seek employment during the past month, as they are counted in the unemployment statistics. This is essential because the unemployment rate specifically targets those who are considered part of the labor force—those who are working or actively looking for work.

Individuals who hold part-time jobs are not included in the unemployment figures, as they are considered employed. Similarly, those who are too frustrated to seek employment are categorized as "discouraged workers" and are not counted in the unemployment figure since they are not actively looking for a job. Therefore, the correct answer includes only those jobless individuals who have shown an active interest in reentering the workforce by seeking employment within the last month.
