<P> Others use dates similar to Strauss and Howe's such as the National Science Foundation's Generation X Report, a quarterly research report from The Longitudinal Study of American Youth, which defines Generation X as those born between 1961 and 1981 . Generation X, a six - part 2016 documentary series produced by National Geographic also uses a 1961--1981 birth year range . PricewaterhouseCoopers, a multinational professional services network headquartered in London, describes Generation X employees as those born from the early 1960s to the early 1980s . </P> <P> Author Jeff Gordinier, in his 2008 book X Saves the World, defines Generation X as those born roughly between 1961 and 1977 but possibly as late as 1980 . Canadian author and professor David Foot divides the post-boomer generation into two groups: Generation X, born between 1960 and 1966; and the "Bust Generation", born between 1967 and 1979, In his book Boom Bust & Echo: How to Profit from the Coming Demographic Shift . On the American television program Survivor, for their 33rd season, subtitled Millennials vs. Gen X, the "Gen X tribe" consisted of individuals born between 1963 and 1982 . </P> <P> Other demographers and researchers use a wide range of dates to describe Generation X, with the beginning birth year ranging from as early as 1960 to as late as 1965, and with the final birth year ranging from as early as 1976 to as late as 1984 . Due in part to the frequent birth - year overlap and resulting incongruence existing between attempts to define Generation X and Millennials, a number of individuals born in the late 1970s or early 1980s see themselves as being on the cusp "between" the two generations . Names given to those born on the Generation X / Millennial cusp years include Xennials, The Lucky Ones, Generation Catalano, and the Oregon Trail Generation . </P> <P> A 2010 Census report counted approximately 84 million people living in the U.S. who are defined by birth years ranging from the early 1960s to the early 80s . In a 2012 article for the Joint Center for Housing Studies of Harvard University, George Masnick wrote that the "Census counted 82.1 million" Gen Xers in the U.S. The Harvard Center uses 1965 to 1984 to define Gen X so that Boomers, Xers, and Millennials "cover equal 20 - year age spans". Masnick concluded that immigration filled in any birth year deficits during low fertility years of the late 1960s and early 1970s . </P>
