What is the phrase babyboomer mean?

A Baby Boomer is someone who was born during the period of increased birth rates when economic prosperity rose in many countries following World War II. In the United States, the term is iconic and more properly capitalized as Baby Boomers and commonly applied to people with birth years after World War II (WW II) and before the Vietnam War, thus possibly comprising more than one generation. The Baby Boom is the iconic term widely used to refer to the American population and culture in particular, as post WW II demographics across the world did not mirror the sustained growth in American families over the same interval.
