Among heads of household, Millennials in 2016 became the generation with the largest number identifying as multiracial. Multiracial Americans are among the nation’s youngest racial and ethnic populations, with a median age of only 19 as of 2015. Many of them have yet to form households, but among those who have, Millennials are now the most prevalent. Around 630,000 multiracial Millennials headed a household in 2016, compared with about 540,000 multiracial Gen Xers and a similar number of multiracial Boomers.
