Those monitoring the tragic news in Mumbai are wondering, "Where is Mumbai?" Mumbai is the city in India
formerly known as Bombay, which India officially changed in 1996. In 2006, the name change finally stuck when the Associated Press announced that it would begin using Mumbai. According to Indian census data, the 2001 population of the Greater Mumbai area was 16,368,084, making it India's largest urban area. The United Nations ranks Mumbai as the world's fifth largest urban area
. Mumbai lies on India's west coast, along the Arabian Sea.
Other Indian cities have changed their name - Calcutta became Kolkata in 2001 and Madras became Chennai at the same time as the change to Mumbai, in 1996.
