In the United States, that change marked the generation with a strong cultural cleavage, between the proponents of change and the more conservative individuals.
Some analysts believe this cleavage played out politically since the time of the Vietnam War to the mid‑2000s, to some extent defining the political landscape and division in the country.
Baby Boomers (also known as Boomers) are the demographic cohort following the Silent Generation.
There are no precise dates for when this cohort starts or ends; demographers and researchers typically use starting birth years ranging from the early-to-mid 1940s and ending birth years ranging from 1960 to 1964.
These monikers include, but are not limited to, "golden boomers", "generation Jones", "alpha boomers", "hippies", "yippies", "yuppies", "zoomers", and "cuspers." Advocates of these "cultural segments" are often zealous and overstated in their attempts to redefine generational boundaries, often claiming wide adoption and sometimes advancing self-promotional agendas.
In Ontario, Canada, one attempt to define the boom came from David Foot, author of Boom, Bust and Echo: Profiting from the Demographic Shift in the 21st century (1997).
As a group, baby boomers were the wealthiest, most active, and most physically fit generation up to the era in which they arrived, and were amongst the first to grow up genuinely expecting the world to improve with time.
