In many ways, Mumbai is today what New York City was in the 1800s: fast growing, squalid, and powered in part by graft and greed. Although new high rises have begun to crowd the Mumbai skyline, only 10 to 15 percent of the city's inhabitants live in actual apartments, some no larger than 48 square feet. The majority, most of whom are poverty-stricken, live in slums, shanties, or chawls—an Indian version of a tenement. But a major difference between modern Mumbai and nineteenth century New York is that its population is four times larger. In the next decade, Mumbai will become a megacity with a population of 22.5 million. And what's more, in New York City, thanks in part to the shocking exposés of investigative journalists like Jacob Riis and the slum clearing policies of President Franklin Roosevelt's New Deal, tenements were largely history by the mid-twentieth century. In contrast, the World Bank predicts that slums are on the rise in Mumbai and will overrun the city by 2025.
