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, published in 1997 and 2000. He defines a Canadian boomer as someone born from 1947 to 1966, the years that more than 400,000 babies were born. However, he acknowledges that is a demographic definition, and that culturally it may not be as clear-cut.[14]
Doug Owram argues that the Canadian boom took place from 1943 to 1960, but that culturally boomers (everywhere) were born between the late war years and about 1955 or 1956. He notes that those born in the years before the actual boom were often the most influential people among boomers; for example, The Beatles, Bob Dylan, and the Rolling Stones and writers like Jack Kerouac and Allen Ginsberg, who were considerably older than the boomer generation. Those born in the 1960s might feel disconnected from the cultural identifiers of the earlier boomers
