Unemployment can take several forms, including demand deficient, structural, real wage, frictional, and voluntary unemployment. There are many causes of unemployment, such as being between jobs, being laid off, or quitting a previous position. High youth unemployment in Tunisia is due to a surge in the youth population combined with a lack of jobs and mismatch between education and market needs. Unemployment can lead to increased poverty, crime, substance abuse, and even suicide. Solutions proposed include improving education quality and practical skills training, encouraging rural development and industries, and rapid industrialization.
