Homelessness occurs for a variety of different reasons. Economic strain, loss of jobs as well as the inability to find more work, drug and alcohol abuse, mental illness, and gross financial management just to name a few. It is imperative that primary prevention strategies such as information, education, and interventions be given to those persons at risk of becoming homeless. The ultimate goal is to prevent homelessness before it happens lessening the stress on the person at risk, and the limited resources available after homelessness has been obtained.
