Millennials (also known as Generation Y) are the demographic cohort following Generation X (mostly in western countries). There are no precise dates for when this cohort starts or ends; demographers and researchers typically use the early 1980s as starting birth years and the mid-1990s to early 2000s as ending birth years. Millennials, who are generally the children of baby boomers and older Gen Xers, are sometimes referred to as "Echo Boomers" due to a major surge in birth rates in the 1980s and 1990s. 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 post–World War II boom.
Millennial characteristics vary by region, depending on social and economic conditions. However, the generation is generally marked by an increased use and familiarity with communications, media, and digital technologies. In most parts of the world, their upbringing was marked by an increase in a liberal approach to politics and economics; the effects of this environment are disputed. The Great Recession has had a major impact on this generation because it has caused historically high levels of unemployment among young people, and has led to speculation about possible long-term economic and social damage to this generation.
Authors William Strauss and Neil Howe are widely credited with naming the Millennials. They coined the term in 1987, around the time children born in 1982 were entering preschool, and the media were first identifying their prospective link to the new millennium as the high school graduating class of 2000. They wrote about the cohort in their books Generations: The History of America's Future, 1584 to 2069 (1991) and Millennials Rising: The Next Great Generation (2000).
In August 1993, an Advertising Age editorial coined the phrase Generation Y to describe those who were aged 11 or younger as well as the teenagers of the upcoming ten years who were defined as different from Generation X. According to Horovitz, in 2012, Ad Age "threw in the towel by conceding that Millennials is a better name than Gen Y", and by 2014, a past director of data strategy at Ad Age said to NPR "the Generation Y label was a placeholder until we found out more about them". Millennials are sometimes called Echo Boomers, due to them being the offspring of the baby boomers and due to the significant increase in birth rates from the early 1980s to mid 1990s, mirroring that of their parents. In the United States, birth rates peaked in August 1990 and a 20th-century trend toward smaller families in developed countries continued. In his book The Lucky Few: Between the Greatest Generation and the Baby Boom, author Elwood Carlson called this cohort the "New Boomers".
