Millennials, the cohort of Americans born between 1980 and the mid-2000s, are the largest generation in the U.S., representing one-third of the total U.S. population in 2013. With the first cohort of Millennials only in their early thirties, most members of this generation are at the beginning of their careers and so will be an important engine of the economy in the decades to come. The significance of Millennials extends beyond their numbers. This is the first generation to have had access to the Internet during their formative years. Millennials also stand out because they are the most diverse and educated generation to date. Perhaps the most important marker for Millennials is that many of them have come of age during a very difficult time in our economy, as the oldest Millennials were just 27 years old when the recession began in December 2007. This report takes an early look at this generation's adult lives so far, including how they are faring in the labor market and how they are organizing their personal lives.
