India's Demographics
India's demographics are the structural backdrop to almost every policy debate: the country is the world's most populous, its fertility has fallen below the replacement level, and it holds a large working-age majority that gives it a time-limited "demographic dividend". This is also a data story. The instruments that measure the population — the decennial census, the Sample Registration System, the National Family Health Survey and the labour-force surveys — are run by different arms of the state, and no census had been completed since 2011 until Census 2027 began its house-listing phase in 2026. The size, age and movement of the population set the electorate, the workforce, the welfare bill and the allocation of parliamentary seats.

Role
India’s demographics are less a single subject than the shared denominator of the Indian state. The size of the population sets the electorate and the welfare caseload; its age structure sets the workforce and the pension burden; its movement reshapes cities and rural labour markets. These facts are produced by a distributed measurement apparatus rather than a single agency. The decennial census, run by the Office of the Registrar General and Census Commissioner under the Ministry of Home Affairs, is the foundational headcount; the Sample Registration System produces official birth, death and fertility rates between censuses; the National Family Health Survey, run by the International Institute for Population Sciences for the Ministry of Health, measures fertility and health; and the National Sample Survey and Periodic Labour Force Survey, run by the Ministry of Statistics, measure the working-age population and, in 2020-21, migration. Because no census was completed between 2011 and the launch of Census 2027, much of the current picture rests on projections and sample surveys rather than a fresh count.
The fault lines run through both the numbers and the institutions that produce them. Fertility has fallen below replacement even as the population keeps growing on momentum, so the debate has shifted from controlling numbers to managing a large working-age cohort — the demographic dividend that ties this desk to labour policy and jobs — while also preparing for accelerating ageing that ties it to social-justice and health spending. The census is doubly political: it carries the first caste enumeration since 1931, and it is the trigger the Constitution names for redrawing the map of parliamentary seats — the delimitation question that connects demographics to the Election Commission and to the balance of power between faster- and slower-growing states.

India adopts the first national family-planning programme
India became the first country in the world to launch a state-backed family-planning programme, beginning the long policy effort to slow population growth that shaped the demographic transition.

National Population Policy 2000 sets a replacement-fertility target
The policy set the medium-term objective of bringing the total fertility rate to the replacement level of 2.1 by 2010 and stabilising the population by 2045, making below-replacement fertility an explicit goal of the state.

Census 2011 counts 121.09 crore people
The last completed census recorded a population of 1,210,854,977 and, on its migration tables, about 45.6 crore internal migrants — roughly 37% of the population — of whom the overwhelming majority moved within their home state.

Economic Survey 2016-17 estimates ~9 million annual inter-state migrants
Using railway-passenger data, the Economic Survey's chapter on migration put the annual inter-state labour migration flow at close to 9 million between 2011 and 2016, well above the pace implied by the decennial census, and flagged that internal migration was rising.

NFHS-5 records the total fertility rate at 2.0, below replacement
The fifth National Family Health Survey found the national total fertility rate had fallen to 2.0 children per woman, below the 2.1 replacement level, confirming that India's population growth is now driven by demographic momentum rather than high fertility.

Census 2021 fieldwork postponed
The house-listing phase of the census, due to begin in April 2020, was postponed indefinitely on account of the COVID-19 pandemic, and was not restarted for years — leaving India without a fresh headcount for the longest interval since the census began in 1881.

India Ageing Report 2023 projects a doubling of the elderly share
UNFPA India and the International Institute for Population Sciences reported that the share of people aged 60 and over would rise from 10.5% in 2022 (about 149 million) to 20.8% by 2050 (about 347 million), with the elderly projected to outnumber children under 15 by around 2046.

Gazette notification (S.O. 2681(E)) sets Census 2027 with a caste enumeration
The Office of the Registrar General notified the census under the Census Act, 1948, by gazette (S.O. 2681(E)), fixing a reference date of 1 March 2027 for most of the country and 1 October 2026 for the Union Territory of Ladakh and snow-bound areas of Jammu and Kashmir, Himachal Pradesh and Uttarakhand. Following the Cabinet Committee on Political Affairs' decision of 30 April 2025, caste is to be enumerated for all groups for the first time since 1931.

Census 2027 fieldwork begins: India's first digital census opens its house-listing phase
The Registrar General described Census 2027 as India's first digital census, with a web-based self-enumeration option in 16 languages and enumerator data collection by mobile app, conducted in two phases — house-listing and housing census, then population enumeration. House-listing operations opened from April 2026 in an initial set of states and Union Territories, with more than three million enumerators and supervisors to be deployed.
