When calculating the unemployment rate, the individual who would be considered unemployed is:
a 22-year-old teacher who recently lost his job and is currently looking for a new one.
The other individuals listed do not meet the criteria for being classified as unemployed because:
- The 65-year-old retired plumber is not actively looking for work.
- The 15-year-old girl, while seeking work, is likely under the minimum age for many jobs and may not be classified in the same way as adults in the labor force.
- The 18-year-old electrician is currently employed, even if he desires more hours.
Thus, only the 22-year-old teacher is actively seeking employment after losing a job, making him the only one fitting the definition of unemployed.
