All of them have density of above 2,000 persons per square kilometer and about 5% of the country’s population lives in these districts. India is a birthplace to two of the world’s largest religions: Hinduism and Buddhism. Hinduism is the largest religion in India and accounts for about 81 percent of the population. It is not merely a religion but also a philosophy and a way of life. It does not originate in the teachings of any one prophet or holy book. It respects other religions and does not attempt to seek converts. About 12 percent of the population practice Muslim religion, and 2.3 percent Christianity. Central to traditional Hindu society is the family, welded together by arranged marriages in which adolescent girls bring negotiated dowries to the selected husband. Such marriages join not simply two individuals but also two families, clans, or even communities. Money, land, tradition, and social convenience all play a part. Times are changing though. With education and birth control more widely available, women now have far greater control over their own lives, and love marriages are increasingly accepted by the middle classes. 6. Infrastructure

Power, transport, and other infrastructure industries are owned by the State. In recent years, the infrastructure industries in India have been growing at the rate of 9 to 10% annually. The generation of power has increased impressively in recent years. India has large reserves of coal and it is its primary source for power generation. It also produces about 57% of its crude oil consumption, and imports the rest. Natural gas production has also increased in recent years. India has an aviation infrastructure, which caters to every aspect of this industry. Within the country, there are five international airports and more than 88 other airports are linked by Indian Airlines. There are over 300 airports in the country. The Government has adopted a liberal civil aviation policy and many private airlines are already operating in the country. The Indian Railway system with its total route length of 63,000 kilometers is the second largest network in the world. It carries more than 4000 million passengers and transports over 382 million tons of freight every year. In recent years the Railways have launched a series of improvements in tracks and plans are afoot to introduce faster trains. The roadways have also grown rapidly in independent India. Ranging from national highways to the roads in remote interiors, the country has a road network of 2.1 million-km.
