Today’s generation of schoolchildren looks much different than it did just a few decades ago. Non-whites are expected to become the majority of the nation’s children by 2020, as our colleague Bill Chappell reported last year. This is now the reality among the very youngest Americans: babies.

Babies of color now outnumber non-Hispanic white babies (one year or younger), according to new estimates from the U.S. Census Bureau. The newest estimate shows that on July 1, 2015, the population of racial or ethnic minority babies was 50.2 percent.

But the scales may have actually tipped in 2013— the Bureau often revises past population estimates as new data become available. That means the first of these babies are now preschool-aged.

We’ve already been seeing this shift in U.S. schools: the 2014-15 school year marked the first time that minority student enrollment in public schools surpassed that of white students.

NPR could not reach any babies for comment.
