Gurgaon, India

This satellite city of Delhi boasts a population of 876,969, but don't be fooled - Gurgaon is a tale of two cities. Behind the gleaming skyscrapers and Fortune 500 headquarters lies a persistent headache of urban flooding, with monsoon storms regularly overwhelming the city's limited drainage capacity. Despite rapid economic growth, Gurgaon continues to battle issues like high air pollution and a reputation for prostitution and sex tourism in certain neighborhoods. For the well-heeled corporate executive or startup founder, Gurgaon may offer the trappings of success, but for the average resident, it's a city that often falls short on basic infrastructure and livability.
