Multiracial youth that identify with two or more of their ethnicities are happier than those who only identify with one, according to a study published by the Stanford Graduate School of Business.
In the study, “The Interpretation of Multiracial Status and Its Relation to Social Engagement and Psychological Well-Being,” multiracial high school students were asked which groups they primarily identified with. Those who identified with multiple groups reported either equal or higher psychological wellbeing and social engagement than those who identified primarily with a single group.
According to the researchers, the ability to claim different ethnicities indicates resiliency; youth who identify with multiple groups can also adapt to different racial environments more easily.
