(I found this while looking for the children's book, which is apparently out of print)
http://www.heritage.org/Research/Welfare/bg1713.cfm“While the poor are generally well-nourished, some poor families do experience hunger, meaning a temporary discomfort due to food shortages. According to the U.S. Department of Agriculture (USDA), 13 percent of poor families and 2.6 percent of poor children experience hunger at some point during the year. In most cases, their hunger is short-term. Eighty-nine percent of the poor report their families have "enough" food to eat, while only 2 percent say they "often" do not have enough to eat.”
“The best news is that remaining poverty can readily be reduced further, particularly among children. There are two main reasons that American children are poor: Their parents don't work much, and fathers are absent from the home.”
“In good economic times or bad, the typical poor family with children is supported by only 800 hours of work during a year: That amounts to 16 hours of work per week. If work in each family were raised to 2,000 hours per year--the equivalent of one adult working 40 hours per week throughout the year--nearly 75 percent of poor children would be lifted out of official poverty.”
“But if poverty means lacking nutritious food, adequate warm housing, and clothing for a family, relatively few of the 35 million people identified as being "in poverty" by the Census Bureau could be characterized as poor.3 While material hardship does exist in the United States, it is quite restricted in scope and severity. The average "poor" person, as defined by the government, has a living standard far higher than the public imagines.”
“Hunger is a far less severe condition: a temporary but real discomfort caused by an empty stomach. The government defines hunger as "the uneasy or painful sensation caused by lack of food."13 While hunger due to a lack of financial re-sources does occur in the United States, it is limited in scope and duration. According to the USDA, on a typical day, fewer than one American in 200 will experience hunger due to a lack of money to buy food.14 The hunger rate rises somewhat when examined over a longer time period; according to the USDA, some 6.9 million Americans, or 2.4 percent of the population, were hungry at least once during 2002.15 Nearly all hunger in the United States is short-term and episodic rather than continuous.16”
