There are more than 58 million single women eligible to vote this November. For the first time ever, there are more single women than married women eligible to vote, and their numbers continue to grow nationally and in key states. And as the new poll of nine battleground states conducted for Women’s Voices Women Vote Action Fund shows, single women could determine the outcome of the presidential election and U.S. Senate races down-ballot.

This chart showing the growth of the Rising American Electorate – unmarried women, people of color, and Millennials – in key states between 2010 and 2016 demonstrates quite clearly how broadly and quickly the face of America is changing.

On February 9, New Hampshire voters will begin to winnow the field of presidential contenders. The New Hampshire primary is the first in the series of nationwide party primary elections (Iowa uses a caucus rather than a primary) and since 1952 it has been a major testing ground for candidates for both the Republican and Democratic nominations. Even though only a few delegates will be chosen in the New Hampshire primary, the massive media coverage it receives can make, break, or revive candidacies. One of the unique characteristics of the Granite State primary is that 60 percent of the voters who turn out in the two primaries have met at least one candidate.

Here’s an updated look at the median earnings, health insurance coverage and poverty rates for unmarried women in 16 states. These profiles provide detailed demographic and economic portraits of the growing number of increasingly politically-powerful single women.

An astonishing number of single women aren’t yet registered to vote. If we help even a small percentage more of unmarried women register and vote, we’d likely see different results up and down the ballot in key 2016 states.
