India Population 2015

India, located in South Asia, is bordered by the Bay of Bengal, the Arabian Sea, the Indian Ocean, Pakistan, Bhutan, China, Nepal, Burma, and Bangladesh. India is the world's 7th largest country by area and the second-most populous with more than 1.2 billion residents. It's also the most populous democratic country in the world. The most recent estimate gives India a population of 1.29 billion in 2015.

The country as a whole has a population density of 384 people per square kilometer (994/square mile), which ranks 31st in the world. In Mumbai, however, the population density is 21,000 people per square kilometer (54,000/square mile).

Largest Cities in India

India's largest city is Mumbai, with a population of 12.5 million, closely followed by Delhi, with a population of 11 million. Overall, there are more than 50 urban areas in India with a population of more than one million people.

Mumbai, which used to be called Bombay, has an official population of 12,478,447, although its wider metropolitan area is much larger - home to 18,414,288 people. It has more than doubled in size in the past forty years – in the 1971 census its population was recorded as 5.9 million – although growth has slowed dramatically in the past decade. Overall population density in the city is 20,482 people per square kilometer.

Delhi, India's second most populous city is home to 11,007,835 people, and its metro area contains 16,314,838 people. Growth in Delhi is even more rapid than Mumbai's, and it is likely that it will overtake Mumbai to become the largest city in India within a decade. The city has struggled to keep up with growth, though – more than half of its residents live in slums, and the city's poverty rate is four times the national average. Contained within Delhi’s boundaries is the city of New Delhi, an enclave city which is the official capital city of India. It has a population of 249,998 people.

Other major cities in India are Bengaluru (pop: 8.43 million), Hyderabad (pop: 6.81 million) and Ahmedabad (pop: 5.57 million). There are 53 cities in India with a population of at least 1 million.

Largest States in India

There are twenty-eight states in India. Their populations range massively in size – the largest holds almost 200 million people, the smallest just over half a million.

India’s largest state is Uttar Pradesh which, with a population of 199,581,520 in 2011, is larger than most countries in the world. If it were a country in its own right, it would be the fifth largest in the world, sandwiched between Indonesia (237 million) and Brazil (192 million).

Two other Indian states are home to more than 100 million people - Maharashta (pop: 112.4 million) and Bihar (pop: 103.8 million). The smallest state in India is Sikkim (pop: 607,688).

India Demographics

Data on ethnicity is not collected by the Indian census, although the CIA World Factbook estimates the population is 72% Indo-Aryan, 25% Dravidian, and 3% Mongoloid and other.

Hinduism is the most common language in India, accounting for 80% of the population. Islam is the second-largest religion at 13% of the population. Other major religious groups in India are Christians (2.3%), Sikhs (1.9%), Buddhists (0.8%) and Jains (0.4%).

Data about the number of people without religion or the number of atheists in India is not collected, largely because the Indian concept of religion is rather different to concepts of religions held in much of the rest of the world – for example, the main religions in India are able to embrace atheism among their members. People who claimed no religion are officially recorded under ‘other’ by the census, but with only 0.6% of Indians fitting within this category, it is not clear how accurate this figure is.

While the number of Indians living in urban areas has increased over the last two decades, about 70% of people still live in rural areas. In 2011, India had a literacy rate of 74%: 82% for men and 65% for women. The literacy rate varies wildly by state, however; Bihar is the least literate with a rate of 64%.

2011 India Census

The 2011 census was the second largest the world has ever seen – second only to China’s census the previous year. It took place in two phases. The first phase, in April 2010, counted all of the buildings in India, and the second phase collected data about the people of India.

The census was a massive exercise, employing millions of Indians. The total cost of the census came to $439 million which, although it seems massive, was actually considerably cheaper per person than most censuses held around the world – the average census costs over $4 per person, whereas the census in India cost just $.50 per person.

The 2011 census was the fifteenth nationwide census carried out in India. The first was held in 1872, although it was not able to cover all of British-held Indian territory. The first comprehensive nationwide census was carried out under the auspices of Lord Ripon, the British Viceroy of India at the time, and counted a population of 288 million in 1881. Since then, a census has been held every ten years in India.
