Marriage is an important part of life, and mixed race marriages are going to skyrocket once early 2010’s kids become adults

(Just a quick disclaimer I have no problem with this so please dont come at me I just thought it was noteworthy to talk about this). I have a family member who works at a school, and according to him, he sees more mixed race couples at said middle schools, and most races try chasing other races for relationships. He did say South Asians tend to stay within their own race but this is very interesting to me as mixed race couples were fairly uncommon when I was growing up, why do you think this changed so quickly?
