Street children
It is difficult to obtain accurate data about them because of their floating character. Street children usually have no proof of identification and move often. Of the 50,000 people in India that are officially reported as leaving home annually, 45 percent are under 16; this number, though, is likely very low. Various studies have formulated estimates of certain cities. In the late 1980s, for instance, it was estimated that there were at least 100,000 street children in both Calcutta and Bombay. Overall, estimates for the total number of street children in India range from 400,000 to 800,000.
