Children living on the street are the most vulnerable, exploited and who face the highest risks in Bangladesh. As a special group of children in grave situation these children are helpless being deprived of the basic necessities of life, such as food, shelter, and clothing and psychological supports. In the absence of the fulfillment of these basic needs, mere survival of the child becomes impossible and they grow up as unwanted members of the society. Because of the negligence they continue to suffer these children grow as child labor, beggars, shoplifters, and pick-picketers, gangsters, low paid domestic servants, and so on. They are often preying to every physical and moral danger and as they grow older they often become a danger to others. After such precarious childhoods, most of them are condemned to spend their lives excluded from mainstream society. This study is designed to understand the dimensions of the problem, assess the physical, psychological, social and basic needs of the street children for their growth and development, and finally to have an empirical database to help formulate the future national policies and programs for street children.
