Generation Z refers to the cohort of people born after the Millennial Generation. There is no agreement on the name or exact range of birth dates. Some sources start this generation at the mid or late 1990s, or from the mid 2000s to the present day.
Generation Y refers to the population group in the US born from somewhere around 1976 to around 2000. They are sometimes called echo boomers because some of them are the children of baby boomers. On the other hand, some Generation Y children, especially those born in the late 1980s or afterwards, may be the grandchildren of baby boomers. Other names for this group are the Millennials, the Internet Generation, and the abbreviated Gen Y or Gen Yers.
