2011 census of India
The 15th Indian census was conducted in two phases, house listing and population enumeration. House listing phase began on 1 April 2010 and involved collection of information about all buildings. Information for National Population Register was also collected in the first phase, which will be used to issue a 12-digit unique identification number to all registered Indians by Unique Identification Authority of India. The second population enumeration phase was conducted between 9 to 28 February 2011. Census has been conducted in India since 1872 and 2011 marks the first time biometric information was collected. According to the provisional reports released on 31 March 2011, the Indian population increased to 1.21 billion with a decadal growth of 17.64%. Adult literacy rate increased to 74.04% with a decadal growth of 9.21%. The motto of census 2011 was 'Our Census, Our future'.
Spread across 35 states and union territories, the Census covered 640 districts, 5767 tehsils, 7742 towns and more than 6 lac villages. 2.7 million officials visited households in 7,935 towns and 6,40,867 villages, classifying the population according to gender, religion, education and occupation. The cost of the exercise was approximately 2200 crore (US$400 million) – this comes to less than $ 0.5 per person, well below the estimated world average of $4.6 per person. Conducted every 10 years,this census faced big challenges considering India's vast area and diversity of cultures and opposition from the manpower involved.
Information on castes was included in the census following demands from several ruling coalition leaders including Lalu Prasad Yadav, Sharad Yadav and Mulayam Singh Yadav supported by opposition parties Bharatiya Janata Party, Akali Dal, Shiv Sena and Anna Dravida Munnetra Kazhagam. Information on caste was last collected during the British Raj in 1931. During the early census, people often exaggerated their caste status to garner social status and it is expected that people downgrade it now in the expectation of gaining government benefits.
There is only one instance of a caste-count in post-independence India. It was conducted in Kerala in 1968 by the Communist government under E. M. S. Namboodiripad to assess the social and economic backwardness of various lower castes. The census was termed Socio-Economic Survey of 1968 and the results were published in the Gazetteer of Kerala, 1971.

The first houselisting phase began on 1 April 2010 and involved collection of data about all the buildings and census houses.

India is the homeland of major belief systems such as Hinduism, Buddhism, Sikhism and Jainism, while also being home to several indigenous faiths and tribal religions which have survived the influence of major religions for centuries.
Ever since its inception, the Census of India has been collecting and publishing information about the religious affiliations as expressed by the people of India. In fact, population census has the rare distinction of being the only instrument that collects this diverse and important characteristic of the Indian population.

The literacy rate taking the entire population into account is termed as "crude literacy rate", and taking the population from age 7 and above into account is termed as "effective literacy rate". Effective literacy rate increased to a total of 74.04% with 82.14% of the males and 65.46% of the females being literate.
