Society and culture
India is a pluralistic(a social system based on mutual respect for each other's cultures among various groups that make up a society), multilingual and multiethnic society. It is also home to a diversity of wildlife in a variety of protected habitats(a specific place or natural conditions in which a plant or animal lives).
With an estimated population of 1.2 billion, India is the world's second most populous country. The last 50 years have seen a rapid increase in population due to medical advances(progress, enhancement) and massive increase in agricultural productivity. India's median age is 24.9, and the population growth rate is of 1.38% per annum. Although there are many large cities, more than 70% of India's population resides in rural areas.
India is home to two major linguistic(pertaining to a language) families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by about 24%). Neither the Constitution of India, nor any Indian law defines any national language. Hindi, with the largest number of speakers, is the official language of the union. English is used extensively in business and administration. It is also important in education.
As per the 2001 census, over 800 million Indians (80.5%) were Hindu. Other religious groups include Muslims (13.4%), Christians (2.3%), Sikhs (1.9%), Buddhists (0.8%), Jains (0.4%), Jews, Zoroastrians and Bahá'ís. Tribals(a socially, ethnically, and politically cohesive group of people) constitute 8.1% of the population. India has the third-highest Muslim population in the world.
