What is expected to happen in America by 2023 as predicted by census trends is that the majority of children will not be Caucasian.
The current "trend" is that many white people marry black or people of Asian descent, which means that their children are no longer Caucasian, but rather a mixture of the two races. Well, in the future, this trend is only going to be more prominent, which will result in fewer Caucasian people in America.
