The "baby boomer" generation generally includes individuals born between 1946 to 1964. By 1965, there were approximately 76.4 million baby boomers in the United States.
Some historians believe the desire for normalcy after World War II led to the baby boom. Others believe it was a Cold War tactic to combat communism. More likely, the baby boom occurred for practical reasons, notes History.com. Many people had postponed having children because of economic hardship stemming from the Great Depression and problems related to the war. They believed the post-war era would bring about a peaceful environment conducive to raising a family. Businesses also began to prosper, and higher wages promised a better standard of living. Also, consumer goods became more widely available, allowing for a more comfortable lifestyle.
