Chennai district, formerly known as Madras district,[a] is one of the 38 districts in the state of Tamil Nadu, India. It is the smallest and the most densely populated district in the state. The district is coterminous with the city of Chennai, which is administered by the Greater Chennai Corporation. It is surrounded by Tiruvallur district in the north and the west, Kanchipuram district in the south-west, Chenglpattu district in the south, and the Bay of Bengal in the east.
As of 2011, the district had a population of 67,48,026 with a sex-ratio of 989 females for every 1,000 males.[6] Much of the district's population descended from its settlements in the 1st century CE to the Middle Ages, but the diversity has grown much since then. The district consists of only one civic body, the megacity of Chennai, which forms the core and the most notable portion of the much bigger Chennai metropolis, or officially, the Chennai Metropolitan Area. In 2018, the district's limits were expanded, aligning with that of the newly expanded Greater Chennai Corporation, which had annexed adjacent municipalities. It resulted in the area being increased from 175 square kilometres (68 sq mi) to 426 square kilometres (164 sq mi).[3][8] The district is divided into three revenue divisions and ten taluks.It has GDP ( PPP ) of $ 143.9 Billion ( as of 2023 )[9]
Etymology
[edit]The name Chennai was derived from Damarla Chennappa Nayak, the father of a general of the Vijayanagar Empire.[10]
Geography
[edit]Chennai district covers an area of 426 km2 located on the Eastern Coastal Plains of India. It is situated on the northeastern corner of Tamil Nadu along the Coramandel coast, a region bounded by the Bay of Bengal and is surrounded inland by the districts of Tiruvallur, Kanchipuram and Chengalpattu. It lies between 12°59' and 13°9' of the northern latitude and 80°12' and 80°19' of the eastern longitude at an average altitude of 6 metres above sea level on a 'sandy shelving breaker swept' beach. Terrain slope varies from 1:5000 to 1:10,000.[11] The terrain is very flat with contours ranging from 2 m to 10 m above mean sea level with a few isolated hillocks in the southwest beyond the district limits at St. Thomas Mount, Pallavaram and Tambaram.[12]
The district runs inland in a rugged semi-circular fashion and its coastline is about 25.60 km (2.5% of the total coastline of Tamil Nadu). Because of its strategic location and economic importance, it is referred to as the "Gateway of South India." The drainage system includes two rivers, namely, Cooum (flowing in the northern part) and Adyar (flowing in the southern part), a canal (the Buckingham), and a stream (the Otteri Nullah) slicing the district into several islands.
The district falls under Seismic Zone III indicating a moderate risk of earthquake. Geologically the district is divided into three regions, namely, sandy, clayey and hard-rock regions. The soil comprises clay, shale and sandstone.[13]
Of the total land area, reserved forests cover 2.71 km2 and is concentrated in and around the Guindy National Park region, one of the few national parks in the world located within a city. The forest cover of the district is as follows:[14]
| Class | Area (Ha) | Percentage |
|---|---|---|
| Dense forest | 151.01 | 1.16 |
| Moderate dense TOF | 121.16 | 0.93 |
| Non-forest | 12,215.56 | 94.06 |
| Open forest | 114.24 | 0.88 |
| Open TOF | 153.73 | 1.18 |
| Water | 231.46 | 1.78 |
| Total | 12,987.16 | 100 |

Notes
[edit]- ^ Both of these terms are also often used as metonyms for the Chennai metropolitan area's trading and financial services industries, which continue a notable history of being largely based in the city. The name Chennai is colloquially used for a far wider area than just the city. Chennai most often denotes the sprawling Chennai metropolis, including parts from the three districts of Tamil Nadu adjacent to the city/district of Chennai itself. This wider usage of Chennai is documented as far back as 1639, when the Madras Municipal Corporation was created.
