Strauss-Howe Generational Theory

The Strauss–Howe generational theory, created by authors William Strauss and Neil Howe, identifies a recurring generational cycle in American history. Strauss and Howe lay the groundwork for the theory in their 1991 book Generations, which retells the history of America as a series of generational biographies going back to 1584.[1] In their 1997 book The Fourth Turning, the authors expand the theory to focus on a fourfold cycle of generational types and recurring mood eras in American history. http://en.wikipedia.org/wiki/Strauss-Howe_generational_theory

Demographers don't buy it. "The Baby Boom is distinguished by a dramatic increase in birth rates following World War II and comprises one of the largest generations in U.S. history," Hogan wrote. "Unlike the baby boom generation, the birth years and characteristics for other generations are not as distinguishable and there are varying definitions used by the public."
