Which cities in the U.S. have the most vacant homes?

It’s a tough question to answer, especially when you’re in the middle of a financial crisis.

And with the housing market in the midst of a recession, some are asking how much of the country’s population is actually living in housing, which is a difficult question to ask.

But a new study released Thursday from real estate firm Hulman Group found that there’s a large gap between the number of vacant homes in the United States and the number that are actually occupied.

According to the report, about 15.5 million people are living in vacant homes.

Of those, nearly 4.4 million (about 20%) are in cities that are experiencing a housing crisis.

That includes some of the nation’s most distressed cities.

In a statement, Hulmann Group said it’s a good time to look at vacant homes, since the number is “unprecedented.”

Here are the top cities in terms of the percentage of people who are living there, as measured by Hulmans website.
