Census-Voting Numbers

Some fun Census/Election math for your reading pleasure 
( TL;DR, get out there and vote, people! ):

As of 2014, eligible voters (18+ and a citizen) who live in 
household that make $0 - $75K a year represent 74M people, 
or 58% of eligible voters.

Eligible voters who live in households that make $75K+ a year
represent 53M people, or 41% of eligible voters.

Both groups had nearly identical voter turn out at 29M people
for the 2014 election.

However 29M is 40% of the $0 - $75K, and 55% of the $75K+. If
an additional 15% of eligible voters voted from the $0 - $75K
group ( to make it even with the $75+ turn out percentage ), 
that would be an additional 11M voters.

To put it that perspective, Barack Obama won against Mitt Romney
by less than 5M votes.

In 2014, only 23.1% of "Millennials" ( voters between 18 - 34
years old ) voted. Millennials are 64M eligible voters strong,
however only 14.7M of them voted.

To put that in comparison, 65+ year old eligible voters are 44M
strong, and 59.4%, or 28M of them voted.

Twice as many folks 65+ voted than those between 18 - 34 in 2014.

Notes: these numbers aren't quite right ( off by up to 10% I'd
say ) since not all individuals reported an income to the Census.
