The growing problem of street children is among the most important child welfare problems today. Estimates are that there are as many as 25 million street children in Latin America alone. This paper, which is based on over five months of fieldwork in Latin America, is a study of the problem of street children. Life on the streets is described in relation to the developmental stages of street children. The paper emphasizes the types of programs that have emerged as the countries of the region seek to ameliorate and prevent this social problem. A program typology is developed and discussed.
