Floods Leave 186000 Homeless, Brazil

Most countries provide a variety of services to assist homeless people. They often provide food, shelter and clothing and may be organized and run by community organizations (often with the help of volunteers) or by government departments. These programs may be supported by government, charities, churches and individual donors.
In 1998, a study by Koegel and Schoeni of a homeless population in Los Angeles, California, reported that a significant number of homeless do not participate in government assistance programs, and the authors reported being puzzled as to why that was, with the only possible suggestion from the evidence being that transaction costs were perhaps too high.
