Millennial Generation Demographics

In 2006, there were 41.9 million 18-29 year old citizens in the U.S., over twice the number of 66-77 year-olds (20.3 million), and twenty-one percent of the overall electorate. 

However, there were also 73.9 million 0-17 year-old residents, almost as many as the Baby Boomers (77 million between the ages of 42 and 60).  35 million of these youth are between the ages of 9 and 17, just a few years away from the electorate. *

By 2015, there will be approximately 82 million Millennials out of an adult citizen population of just over 225 million, or more than 36 percent – one third of the U.S. electorate. **

* According to an analysis conducted by CIRCLE of U.S. Census Bureau’s March 2006 Current Population Survey (CPS).

** According to an analysis conducted by Young Voter Strategies of the U.S. Census Bureau population projections for 2000 to 2050, in 2015 the total 18-38 population will be 90,672,110; applying the 2006 citizenship rate (March 2006 CPS), there are projected to be 81,994,789 citizens between 18-38 years of age in 2015.  In 2015, the total U.S. adult population (18+) is projected to be 245,347,376 (according to the U.S. Census Bureau population projections for 2000 to 2050). Applying today’s citizenship rates for that cohort (91.6% according to the U.S. Census Bureau’s March 2006 CPS), in 2015 the total adult citizen population (18+) is projected to be 224,837,397.
