One new study found that baby boomers (ages 49 to 67 in 2013) are living longer than people roughly 20 years older, but are not healthier.1 While they are less likely to smoke, have emphysema, or a heart attack, they are more likely to be obese, have diabetes, or high blood pressure than the previous generation at similar ages.
The baby boomers are the generation that was born following World War II, generally from 1946 to 1964, a time that was marked by an increase in birth rates. The term baby boomer is sometimes used in a cultural context. Therefore, it is impossible to achieve broad consensus on a defined start and end date.
