Everyone knows that money is tighter now than ever, but its still surprising to see the results of a new survey about buying food.

Over 18 percent of Americans can name at least one instance in the past 12 months where they couldn't afford to buy food.

Almost 180,000 Americans whether there have been times money to buy food for themselves or their families was unavailable.

Mississippi, Alabama and Delaware were the states with the most severe situations. Almost 25 percent of people in Mississippi answered yes.

The states with populations least likely to struggle to afford food were North Dakota at 9.6 percent. That was followed by South Dakota and Vermont.
