In the last few years, the phenomenon of young people not in education, employment or training (NEET) in Mexico has come to the forefront due to the risks related to this situation. This paper analyzes their composition, its dynamics, poverty patterns, and individual and family characteristics. Most of NEET youngsters are women performing household tasks, and live in conditions of high poverty. The number and proportion of NEET have been going down in the last few decades and it is expected this trajectory will continue because it is driven by an increase in the proportion of women who continue studying and join the labor force. However, a higher proportion will correspond to unemployment which will be important to foreseeable public programs.
