Baby Boomers make up the largest generation of Americans born in United States history. Boomers include anyone born between the years 1946 and 1964, as the number of births began to rise as World War II veterans returned home from battle. The greatest number of Baby Boomers were born in 1957, when numbers peaked at 4,300,00. That equates to roughly 8 children born per minute throughout the year. By 2019, the last of the Baby Boomers, or those born in 1964, will be eligible for many senior benefits offered to people age 55 and up. Ten years later, most will be eligible for retirement.
