"The other thing that’s going on is increasingly more and more people are delaying marriage," said Cichy. "They’re delaying having children. They’re pursuing advanced education, you know, going on to graduate school or medical school.

Cichy said it’s likely the Census numbers reflect longer term changes to our society. She said it’s become more socially acceptable for young adults to live with their parents longer.
