The term "street child" has come to refer only to the last group. UNICEF defines a street child as, "...any girl or boy[6] ... for whom the street (in the widest sense of the word, including unoccupied dwellings, wasteland, etc.) has become his or her habitual abode and/or source of livelihood; and who is inadequately protected, supervised, or directed by responsible adults".[2] It is important to distinguish the group of children that live on their own on the streets because their lives vary greatly from those of children who simply work on the streets; they thus have different needs and require targeted attention.[3]
