Statistics on homelessness in the United States are tough to calculate. For many it’s a temporary condition, and and it’s difficult to count those living on the street. But National Coalition for the Homeless Executive Director Neil Donovan told the NewsHour that an estimated 700,000 people are unhoused in the U.S. on any given day.

Over the course of a year, about 3.5 million Americans will spend some time without housing. Of those roughly 700,000 people who will be homeless on Election Day, Donovan said that approximately 70 percent would be eligible to vote, while about one in 10 would be registered and actually cast a ballot. Donovan said the figures disprove the common assumption that homeless people don’t vote at all.

For comparison, 225 million Americans voted in the 2008 presidential election.
