Census Counts and Electoral Rolls

A census count measures the population through a comprehensive demographic enumeration, whereas an electoral-roll count measures persons registered to vote in a particular constituency. They differ in purpose, eligibility, territorial basis, timing and legal administration, so one cannot be treated as a proxy for the other.

Different coverage and purpose

The census supplies population and socio-economic data for administration, planning and statistical use. Electoral rolls identify the persons legally entitled to vote and enable the conduct of elections.

• The census includes persons irrespective of citizenship, age or voting eligibility, while electoral rolls include only eligible electors.
• Under Article 326, an elector must be an Indian citizen, be at least 18 years old and not be disqualified on constitutionally permitted grounds.
• Electoral registration is linked to ordinary residence in a constituency under the Representation of the People Act, 1950.

Different legal and institutional frameworks

Census operations are governed by the Census Act, 1948 and fall within the Union's legislative field. Electoral rolls are prepared under the constitutional supervision of the Election Commission of India.

• Article 324 vests the superintendence, direction and control of electoral-roll preparation and elections in the Election Commission.
• Article 325 requires one general electoral roll for every territorial constituency and prohibits exclusion solely on grounds of religion, race, caste or sex.
• The Representation of the People Act, 1950 regulates electoral registration, qualifications, disqualifications and roll revision.

Different character of the resulting data

A census records population with reference to a specified enumeration period and produces aggregated demographic statistics. An electoral roll is a constituency-specific administrative register that is revised to reflect additions, deletions, corrections and changes of ordinary residence.

• Census information is protected by statutory confidentiality, while electoral rolls must be available for scrutiny so that claims and objections can be made.
• A person counted in the census may be a minor, non-citizen or otherwise ineligible to vote; an eligible citizen may also be absent from a roll because registration requirements have not been completed.
• Therefore, discrepancies between census population and roll totals do not by themselves establish wrongful inclusion or exclusion.
