皮尤研究：The Modern American Family

 

The American family has undergone significant change in recent decades. There is no longer one predominant family form, and Americans are experiencing family life in increasingly diverse ways.

In 1970, 67% of Americans ages 25 to 49 were living with their spouse and one or more children younger than 18.

Over the past five decades, that share has dropped to 37%.
