These numbers are based on data from the National Center for Education Statistics, which is part of the U.S. Department of Education. They are derived from surveys and estimates, so the actual numbers may vary slightly.
The number of children enrolled in school can fluctuate year to year due to various factors, such as changing birth rates, immigration, and migration patterns. For the most up-to-date information on school enrollment in the United States, I recommend referring to the National Center for Education Statistics website.
