Chart: US Population By Generation & Gender

Marketers focus a lot of energy on Millennials. Their lives are deconstructed on many different levels, from their entertainment choices to their views on companies’ ethics and their socioeconomic characteristics. 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 most recent data out from the Census Bureau gives a sense of how large each living 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, other studies might use an 18-29 range or some other, making it necessary to identify age ranges when referring to this cohort.

Another issue? Consider this. If a 2010 study defined Millennials as being aged 18-34, shouldn’t the same study this year define them as being aged 27-43? Somehow the 18-34 age range stays fixed despite the passage of time…

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.)
