In a 2015 study that used a broader definition of the term – one that took into account how adults described their own race as well as the racial background of their parents and grandparents – Pew Research Center estimated that 6.9% of the U.S. adult population could be considered multiracial. The 2015 study also explored the attitudes and experiences of these adults, revealing the complexities of multiracial identity. Here are five key findings from that report:
