From Poverty Awareness Month:

"Although poverty rates declined slightly from 1999 to 2000,
more than 32 million Americans still live in poverty. The
breadth of poverty includes farm families, immigrants, the
working poor, undereducated adults, the disabled poor and
children of all ages. One out of every six children in America
lives in poverty.

The U.S. Census Bureau considers the poverty threshold for a
family of four to be $17,184. Other studies have shown that
Americans believe it takes closer to $35,000 annually to
adequately house, clothe and feed a family of four."

There's a big leap from being "poor" to being "hungry".
