Different definitions of homelessness are used in different contexts. Generally, homelessness is defined as a person who "lacks a fixed, regular, and adequate night-time residence."
Although homelessness is a difficult number to measure definitively, it appears that more people—especially families—are sleeping in shelters, living in their cars, and taking up residence in tent communities.
One out of 50—or about 1.5 million—American children are homeless each year, according to a 2009 study by the National Center on Family Homelessness.
According to the National Alliance to End Homelessness, 23 percent of homeless people are reported as chronically homeless. According to HUD's definition, a person who is "chronically homeless" is an unaccompanied homeless individual with a disabling condition (e.g., substance abuse, serious mental illness, developmental disability, or chronic physical illness) who has either been continuously homeless for a year or more, or has had at least four episodes of homelessness in the past three years. In order to be considered chronically homeless, a person must have been sleeping in a place not meant for human habitation and/or in an emergency homeless shelter.The number of Homeless people in the US 1,750.000 and the average monthly income for an individual is $ 348.00 dollars. The percent of cities surveyed that identified domestic violence as a primary cause of homelessness is 46% and the number of Americans who now live in hunger or on the edge of hunger 31,000.000 making the families with children at 36% .Long Beach, a city of approximately 460,000 south of Los Angeles, has the fourth highest rate of people living without shelter of any major American city. Long Beach listed 1,112 chronically homeless, along with 14,840 chronically homeless in Los Angeles city and county, the highest number in the HUD report. Long Beach also has the 10th largest population of homeless veterans of any major city, 527, compared to Los Angeles city and county’s 6,291. Statewide, the number of homeless people living in shelters and living on the streets increased by 3,895 people since 2010, according to local homeless housing and service providers.
The report also found that California has 22 percent of America’s homeless population, and that 66.7 percent of the homeless lack shelter, the highest percentage in the nation. In addition, 36 percent of America’s chronically homeless reside in California, and of these people 86.6 percent were unsheltered.
