What is the number of citizens under the age of 21 that are not working?

To accurately determine the number of citizens under the age of 21 who are not working, you would need access to specific labor statistics or demographic data from a reliable source, such as the U.S. Bureau of Labor Statistics or similar organizations in other countries. This information can vary significantly by location and over time. Generally, it includes factors like unemployment rates, school enrollment, and economic conditions. If you need precise figures, I recommend checking the latest reports or databases for the most current data.
