Hungry and homeless people have increased significantly in American cities. The US Department of Agriculture said in a report released on November 14, 2007 that 35.52 million Americans, including 12.63 million children, went hungry in 2006, an increase of 390,000 from 2005. About 11 million people lived in "very low food security" (Over 30 Million Americans Faced Hunger in 2006, Reuters, November 15, 2007). Results of the 2007 Hunger and Homelessness Survey released by the US Conference of Mayors showed that 16 of the 23 polled cities reported increased requests for emergency food assistance. Among 15 cities that provided data, the average increase was 12 percent. Detroit reported an increase of 35 percent. In 13 survey cities, 15 percent of households with children were not receiving emergency food assistance they requested. In 20 survey cities, 193,183 people applied for emergency shelter or transitional housing. The number of residents applying for government rent subsidies surged by 30 percent in Baltimore County in 2007 (More Seeking US Rent Subsidy, The Baltimore Sun, December 17, 2007). It is estimated that 750,000 people are homeless on any given day in the United States (Care Critical for Homeless, The Washington Post, October 22, 2007). Los Angeles County has more than 73,000 homeless people (Dying Without Dignity: Homeless Deaths in Los Angeles County, Los Angeles Coalition to End Hunger and Homelessness, December 27, 2007). Phoenix has 7,000 to 10,000 homeless people and another 3,000 who were not sheltered by the government (Rebelion, Spain, January 2, 2008). New Orleans has 12,000 homeless people (Katrina's Wrath Lingers for New Orleans Poor, USA Today, December 13, 2007). California has about 50,000 veterans living in streets (Sing Tao Daily San Francisco Edition, November 8, 2007). Health conditions of the homeless are worrying. Research shows one-third to half of the homeless have a chronic illness. The life expectancy for a homeless person ranges between 42 and 52 years (Care Critical for Homeless, The Washington Post, October 22, 2007). Among sexual offenders in many American cities, the homeless account for a high proportion. In Boston, nearly two-thirds of 136 high-risk sex offenders lack permanent addresses. In New York City, more than 100 sex offenders are registered at two homeless shelters (Many Sex Offenders Are Often Homeless, USA Today, November 19, 2007).
