The number of Americans struggling to put food on the table remains at record levels, according to new government data.

The USDA reports about one out of every six Americans had trouble coming up with enough money to buy food at some point last year. And childhood hunger is a major problem— nearly one in five children lives in households that struggle to provide food.

That's nearly 49 million people—14.5 percent of the population—a figure virtually unchanged from the previous year. The numbers from the past three years are the highest on record since the USDA first began publishing food insecurity data in 1995.
