How many elementary schools in the US?

There's no single, definitive answer to how many elementary schools are in the US. The number fluctuates due to school closures, openings, and varying definitions of "elementary school" (some districts might combine grades differently). The National Center for Education Statistics (NCES) provides data on schools, but it doesn't offer a precise count solely for elementary schools. You'd need to compile data from many sources at the state and local level to get a close approximation, and that would still be a snapshot in time.
