According to the United States government, people are classified as homeless if they have

no place to stay and no expectation of finding a place for the next thirty days. Although technically accurate, that is an impersonal assessment of an enormous and very human problem.

The homeless population represents all of us Americans. It includes men and women, the elderly, children, and infants. Its members are from all ethnic(种族的) groups. What they have in common is poverty.

Currently in the U.S., thirty-nine million people live in poverty. When money is really tight, paying the rent or buying food often becomes a choice. Government assistance in the form. of food stamps does help but, as one homeless man explains, you can't pay the rent with food stamps.

With no money for rent, the streets and homeless shelters become the alternative. Although men constitute the largest group within the homeless population, homeless women with children are rapidly joining them. In fact, one quarter of the homeless people in the U.S. are teenagers and young children.

People may become homeless for numerous reasons. However, there are certain factors that many of these individuals have in common. They include a lack of adequate education and job skills. A majority of the teenagers and adults have not completed high school.

The abuse of alcohol and drugs is also a common factor One third of the adult homeless population abuses alcohol, while one quarter of the same group uses drugs.

Some members of this population suffer mental health problems. Within the past several years many institutions for the mentally ill have been closed and their patients sent "home". Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves.

Job loss in today's economy has also become a real factor in the loss of people's homes. The breakup of families through abandonment and divorce are also contributing factors, particularly when there are children involved. The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads.
