Slums are a worldwide urban phenomena and is usually viewed with a negative biasness- ‘a rash on city landscape,’ a ‘blot on civilization,’ over-crowding, filth, sub-standard housing, drinking, vice, violence, apathy and poverty. A positive attitude is to recognize slums as a ‘component’ of city evolution, an ‘element of urban complex’ as a ‘transitional settlement’ at that low level of survival, and to appreciate the contribution of the slum dwellers to the city’s low-wage labour force and its gross product. This book is a study on the same.
