2011 census of India
15th Indian census

The 2011 census of India or the 15th Indian census was conducted in two phases, house listing and population enumeration. The House listing phase began on 1 April 2010 and involved the collection of information about all buildings. Information for National Population Register (NPR) was also collected in the first phase, which will be used to issue a 12-digit unique identification number to all registered Indian residents by Unique Identification Authority of India. The second population enumeration phase was conducted between 9 and 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 17.70%. Adult literacy rate increased to 74.04% with a decadal growth of 9.21%. The motto of the census was Our Census, Our Future.
Spread across 28 states and 8 union territories, the census covered 640 districts, 5,924 sub-districts, 7,935 towns and more than 600,000 villages. A total of 2.7 million officials visited households in 7,935 towns and 600,000 villages, classifying the population according to gender, religion, education and occupation.
Begin with the source’s own compact description: “2011 census of India” is 15th Indian census. The dossier treats that line as a proposition to test through census, India and 15th, not as a finished interpretation.
Why this record matters
The phrase “15th Indian census” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q1861882. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2011, 2010 and 1872.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
