The informal term slumdog refers to a slum dweller, a person, especially a young person or child, who lives in an area of a town or city where there is extreme poverty and living conditions are particularly bad, with poor sanitation and makeshift housing.
Though slums exist in many parts of the world, evidence of use seems to suggest that slumdog is so far confined to India, referring to the inhabitants of slums in the country's big cities. Official surveys reveal that 65 million Indians â around a quarter of the urban population â live in slums. Contrary to expectation, slumdog doesn't seem to be particularly offensive â it carries negative connotations of course, but seems to be being used as an informal term of reference rather than an insult.
