An internal sample survey carried out by the Slum department of the Municipal Corporation of Delhi has revealed a large number of interesting and at times surprising facts about the Capital's slum dwellers. Carried out last month as part of the MCD drive to relocate more than 75,000 juggis from the Yamuna Pushta, the survey gives details about various aspects of the slum dweller's life including their place of origin, duration of stay in the Capital, average family size, education, age profile, occupation, distance from place of work, pattern of expenditure and savings.
