Generation Y, also known as the Millennial Generation, are the demographic cohort following Generation X. There are no precise dates for when Generation Y starts and ends. Commentators use beginning birth dates ranging from the early 1980s to the early 2000s (decade).  Millennials are sometimes called Echo Boomers, due to the significant increase in birth rates during the 1980s and into the 1990s. Millennials are mostly the children of baby boomers or Gen Xers. The 20th century trend toward smaller families in developed countries continued, however, so the relative impact of the “baby boom echo” was generally less pronounced than the original boom.
