The "Baby Boom" started in 1947 and lasted until 1964, placing the 1950s in the middle of this large growth of the population. By the time the "baby boom" ended, there were over 76.4 million babies that had been born, making up more than 40% of the United States's population. The "baby boom" probably occurred because after the war, people were confident that the United States would experience prosperity and growth and they believed they would be able to support their family. Many people also waited until after the Depression and World War II to have children because they wanted safety and security for their family, so when the war ended, even older Americans were eager to finally have a family. The "baby boom" had a large effect on women, causing more women to leave their jobs to become stay-at-home moms; this placed the "baby boomers" in the center of life during the 1950s. The "baby boomers" had a big impact on merchandise and manufacturers because babies and children became the main target for customers; during this time the Barbie, hula hoops, and frisbee became popular toys, as well as children wearing Mickey Mouse ears. As the "baby boomers" grew up, many began to leave the suburban lifestyle after being surrounded by it for years, and they began fighting with disadvantaged groups for equal rights. The "baby boom" changed and affected many aspects of the 1950s society.
