Answer:
Long-term unemployment.
Explanation:
When people are unable to find a job for an extended period of time, they may become discouraged and stop actively seeking employment. These individuals are no longer counted as unemployed in official unemployment statistics, which can make it difficult to get an accurate picture of the labor market. This is why economists often look at a variety of measures, including the unemployment rate, labor force participation rate, and the number of discouraged workers, to gain a more comprehensive understanding of the employment situation in an economy.
