American values have changed dramatically since 1900. As a result, so has the typical American family. This volume of the "Gallup Major Trends & Events: The Pulse of Our Nation 1900 to the Present" series explores how and why. Families have evolved from several generations living together, to smaller, spread-out households. Today, divorce and single parenthood are no longer scandalous and unconventional families are increasingly common. Weddings occur later in life, and many couples are choosing to have fewer, or no, children. Stay-at-home mothers are now the exception rather than the norm, forcing parents to juggle work and home life. Gallup Organization polls trace how American attitudes about family and marriage issues have altered through the century, and what this implies for the future.
