How many preschool and elementary school students are there in the us?

There's no single, readily available, perfectly accurate number for the total of preschool and elementary school students in the US. The data is collected in different ways by different organizations, and there's always a slight lag in reporting.

To get an estimate, you'd need to combine data from:

* Preschool: Data on preschool enrollment comes from the National Center for Education Statistics (NCES) and may vary depending on whether it includes publicly funded preschool programs, private preschools, or both. The numbers fluctuate year to year.

* Elementary School: The NCES also provides data on elementary school enrollment (typically grades K-5, though some districts might organize grades differently). Again, yearly fluctuations exist.

To find the most up-to-date figures, I recommend checking the NCES website directly. Search for "preschool enrollment" and "elementary school enrollment" on their site. You will likely find reports with detailed breakdowns and you can then add the numbers from those reports to get an approximation. Keep in mind that this will be an estimate, and the exact number will depend on the definitions used and the year of the data.
