The US middle class families without enough to eat

Throughout the 2012 presidential campaign, the BBC has returned to Levittown, Pennsylvania to explore issues facing America's middle class.

At a basement food pantry in suburban Pennsylvania, 2,000lb (907kg) of food are given to roughly 160 families a week.

The majority of families come from the Levittown neighbourhoods - an iconic planned suburb that once ushered in the era of a post-World War II American dream.

But times have changed and even in quiet, leafy suburbs families now struggle with the basic needs of food and shelter. The number of residents using food pantries has risen dramatically over the past few years throughout the county.

Even those who have jobs can still find the cost of living is too high to make ends meet, as the BBC's David Botti reports.
