The Census Bureau just released its annual estimates of the US population, broken out by race, sex, and age. One of the most intriguing results they reported on was that 2014 was the first year in US history in which a majority of children under the age of 5 were identified as some racial and ethnic group other than non-Hispanic white alone. According to the Census Bureau's estimates, 50.2% of young children were non-white.

Here's the racial and ethnic breakdown of children under 5 in 2014. Note that the Census Bureau makes estimates about race and Hispanic origin separately. Here, each group other than Hispanics are understood as non-Hispanic, and children identified as Hispanic can be any race:
