There is a significant degree of consensus around the date range of the baby boomer cohort with the generation considered to cover those born from 1946 to 1964 by various organisations such as the Merriam-Webster Online Dictionary, Pew Research Center, U.S. Bureau of Labor Statistics, Federal Reserve Board, Australian Bureau of Statistics, Gallup, YouGov and Australia's Social Research Center. The United States Census Bureau defines baby boomers as "individuals born in the United States between mid-1946 and mid-1964." Landon Jones, in his book "Great Expectations: America and the Baby Boom Generation" (1980), defined the span of the baby-boom generation as extending from 1946 through 1964.
