In 2015, the most common age for white Americans was 55, according to Census Bureau data reported by the Pew Research Center. For minorities, who include everyone except single-race non-Hispanic whites, more than half (56%) were Millennials or younger.
One reason why non-Hispanic whites are disproportionately older is because they were the biggest population gainers from the post-World War II baby boom – an era before many of today’s minority immigrants entered the country. Whites were the only racial or ethnic group in which Baby Boomers (27% of whites) outnumbered Millennials (21%) in 2015.
While minorities made up just 38.4% of the U.S. population last year, that figure is up slightly from 38.0% in 2014. The minority population grew at a faster pace (2.0%) than the white population (0.1%) during that time. Minorities’ higher growth rate is expected to continue, and the minority population will likely surpass whites in the next several decades. Today, Americans under the age of 5 are already “majority minority,” though by only a small margin.
