The typical American family is not the same structure it was a generation ago. Social and economic dynamics have changed what is considered normal in society. A two-parent household with children is no longer the median version of today’s family.

According to the U.S. Census Bureau, the average number of people per household was calculated at 2.59 during the 2000 census. More people own homes, as the census reported that more than 66 percent of Americans were homeowners. In 2008, the median income for American families was approximately $52,000 yearly, the census bureau reported.

More families are being run by single parents, and the number is set to increase. According to Americans for Divorce Reform, approximately 50 percent of all marriages will end in divorce if current trends continue on the course they are headed. Most divorces occur with young people, as more than 80 percent of divorces are with couples under 30 years old.

American families used to have a large number of children to compensate for high mortality rates. Since the 1970s, the number of children has been under two per household for most American households, according to Stanford University.
