Chennai History

Chennai, which was once known as Madras, is India’s 4th largest city – and the 6th most populated region in the country. Located off of the Coromandel Coast, this city was first discovered a whopping 400 years ago. Chennai sports the impressive title of being the 31st largest city in the entire world.

What is now the modern-day bustling city of Chennai also used to be known as Fort St. George, which was an English settlement. People known as Vijayanagars were in charge of the region when the settlement was first established – a status given to them by the Nayaks – who had control over much of India 400 years ago. One person was appointed as the man in charge of this past Chennai, who went by the name of Damarla Venkatadri Nayaka. Nayaka was also a Telugu King and a chieftain for King Peda Venkata Raya.

Chennai got its name from a small town called Chennapattanam. This village was named after Nayaka’s father, Damerla Chennappa Nayaka – who controlled many regions along the coast of India.

Chennai Population Growth

Chennai has a continued pattern of steady growth. Chennai has the fourth highest population of people lviing in poverty in India, estimated at 820,000, or 19% of the city's total population, according to the census conducted in 2001. The city does well with its female to male ratio, with 1000 males for every 951 females. The density of this populous city continues to tighten every year, though the growth is much slower compared to other major cities. Ever since India’s 1947 independence, the population’s growth slowed by 3-4 percent. This does not stop the country in general from a healthy population growth rate, which is predicted to reach 50 million people by 2025. However, with birth rates continuously falling, the growth is not like the massive spikes seen in previous eras. Despite these drops, Chennai and the rest of India is expected to match China’s overall population by 2020.
