Marketers tend to focus a lot of energy on Millennials. Their lives are deconstructed on many different levels, and there’s research to be found on anything ranging from their top financial goals to the ways in which they use their phones. Those analyses are all helpful in their own right, but – stepping back to the big picture for a moment – how many of these prized individuals are there in the US? The latest data out from the Census Bureau gives a sense of how large this coveted generation is.
Before putting out some numbers, there are a few problems to take note of. Chiefly, there is no consensus definition of a Millennial; while 18-34 seems to be the most commonly used bracket (and one which doesn’t appear to change with each passing year!), other studies might use an 18-29 range or some other, making it necessary to identify age ranges when referring to this cohort. That’s why Pew Research’s declaration that there are now more Millennials than Baby Boomers makes sense in some light, but not in others. (The Washington Post does a great job of delving into that claim in this article, which also includes a useful interactive graphic.)
Meanwhile, it’s also worth noting that most Millennials don’t even identify as Millennials, and a young Gen Xer might feel more culturally similar to Gen Y. In other words, cultural and behavioral tendencies don’t tend to have fixed age breaks. (That’s why many argue that it’s more useful to look at personas rather than age brackets.)
Nevertheless, things being the way they are, marketers and researchers often look at age groups. So here’s a reference list of some commonly used age brackets and their corresponding population estimates and population shares as of July 1st, 2015.
Some other popular age groups, including the ever-present 18-34 bracket:
