William Frey, the demographic expert at Brookings, writes that “the 2020 census is likely to show that children of color will comprise more than half of the nation’s total child population, with Latino and Hispanic children comprising 25.5% and Black children comprising 13.8%. Moreover, as younger, diverse generations age (and due to some projected immigration), more than half of the projected young labor-force-age population (ages 18 to 34) in 2030 will be people of color. This stands in contrast to the 35-and-older population, where white Americans are projected to comprise a substantial majority (62%).
A child is a person under the age of 18.
Texas and Florida are dramatic examples of the shift away from white children. Here are the net changes in the child population from 2010 through 2018.
