Population & Demographics

📊 High-Yield Data & Statistical Fact Sheet

Cue Words	Notes
National TFR (NFHS-5)	Declined to 2.0 (below replacement rate 2.1). 31 States/UTs achieved TFR ≤ 2.1. **UN World Population Prospects (2025 revision)**: TFR estimated even lower at **~1.9-1.93**, with population at **~1.46 Billion** (world's largest), projected to **peak around ~1.7 Billion** in the next ~40 years before declining. Sharp regional divide persists: high-fertility Bihar/UP/Jharkhand vs low-fertility Kerala/Delhi/TN.
Census 2027 & Delimitation	India's next Census will be **digital-first**, conducted in **two phases** (2026 houselisting, Feb 2027 population count), and will **include caste enumeration nationwide for the first time since 1931**. Results expected around **1 March 2027**. **Delimitation link**: The first delimitation since 2011 is expected to follow Census 2027, requiring a new Delimitation Act (and possibly amending Art 81's 550-seat Lok Sabha cap) — southern states have flagged concerns over reduced parliamentary representation.
Land & Population Ratio	India hosts ~17.8% of global population on 2.4% of global land area (464 persons/sq km).
Dependency Ratio	Favorable at 49.2 (vs global average 54.36). Senior citizen population (≥ 60) projected to reach 20% by 2050.
Population Policy 2000 Target	Targeted population stabilization by 2045.

1. THE DEMOGRAPHIC TRANSITION THEORY

Cue Words	Notes
Demographic Transition Stages	**Stage I**: High Birth Rate & High Death Rate (Stable/Low growth). **Stage II**: High Birth Rate & Falling Death Rate (Population Explosion). **Stage III**: Falling Birth Rate & Low Death Rate (Growth slowing). **Stage IV**: Low Birth Rate & Low Death Rate (Stable/India entering).
Expansive Population Pyramid	Wide base, indicating high birth rates and a young population.
Stationary Population Pyramid	Cylindrical structure, indicating stable birth and death rates.
Constrictive Population Pyramid	Narrow base, indicating declining birth rates and an aging population.

2. THE DEMOGRAPHIC DIVIDEND & SKILL DEVELOPMENT

Cue Words	Notes
Demographic Dividend	Economic growth boost when working-age population (15 to 64 years) outnumbers dependents.
NSQF Skill Framework	Competency-based framework organizing qualifications into 10 levels.
PMKVY Skill Scheme	Flagship skill certification offering short-term training and Recognition of Prior Learning (RPL).

3. MIGRATION & URBANISATION TRENDS

Cue Words	Notes
Push vs Pull Migration Factors	**Push factors**: Rural unemployment, low wages, land fragmentation. **Pull factors**: Urban jobs, better wages, education, and healthcare access.
Types of Internal Migration	Classified by direction as rural-to-urban, rural-to-rural, urban-to-urban, and urban-to-rural — rural-to-urban dominates India's internal migration flow.
Urbanisation Rate	India remains majority-rural (~65-69% rural population) but is urbanising steadily, driven by both migration and reclassification of rural areas as towns.
Sex Ratio & Child Sex Ratio	**Sex Ratio**: Females per 1,000 males in total population. **Child Sex Ratio (0–6 yrs)**: A more sensitive indicator of sex-selective practices, tracked via Beti Bachao Beti Padhao.

4. DEMOGRAPHIC DIVIDEND WINDOW & THE JOBLESS-GROWTH DEBATE

Cue Words	Notes
Dividend Window Length	**Demographic dividend** = a **20-30 year window** when working-age share peaks; per Economic Survey 2012-13 (Ch. 2, "Seizing the Demographic Dividend"), India expects this phase to end around **2045**, by when a stable, balanced population is targeted.
Optimism vs Pessimism on the Dividend	**Optimists**: Falling dependency ratio → more workers, savings, capital per worker; high-growth states (TN, Karnataka, Gujarat) historically had ~8.7 percentage-point lower dependency ratios than low-growth states (Bihar, MP, UP). Productivity peaks at age **40-49**, and India will expand this cohort while China/Korea/US contract it. **Pessimists**: A bigger workforce raises growth only if **productive jobs exist** for it; the real test is whether industry/services can absorb workers leaving agriculture.
Why WAP Growth Contributes Little Directly	Growth-decomposition studies find the rising working-age population share added only ~0.5 percentage points to India's per-capita income growth since 1991 — the dividend's real effect flows indirectly through higher labour productivity (more capital/worker, more human capital/worker, higher TFP), not merely a larger labour force.
'Missing Jobs' Projections (Economic Survey 2012-13)	Holding 2010 LFPR/unemployment constant, an estimated 2.8 million jobs would be missing by 2020 as agriculture's employment share fell toward 40%; under a higher female-LFPR scenario (58%) this rises to 16.7 million, and under a falling-unemployment scenario to 11.8 million — illustrating the dividend can turn into a "demographic curse" without adequate non-farm job creation.

5. HUMAN DEVELOPMENT INDEX (HDI) & GENDER INDICES

Cue Words	Notes
HDI: Three Core Dimensions	UNDP's Human Development Index combines three dimensions: (i) Life Expectancy (long & healthy life), (ii) Access to Knowledge (mean + expected years of schooling), (iii) Standard of Living (GNI per capita, PPP $). India historically fell under the medium human development category (HDR-2013: HDI 0.554, rank 136/187), rising from 0.345 in 1980 — an ~61% increase over three decades, driven mostly by rising GNI per capita.
Gender Inequality Index (GII)	Measures inequality in reproductive health, empowerment, and economic activity. Tracks metrics like Parliamentary seat share held by women, secondary-education attainment gap, maternal mortality ratio, and female vs male labour-force participation gap — used alongside HDI to flag that aggregate HDI gains can mask gender disparity.
HDI vs MPI: Complementary, Not Substitute Measures	HDI captures average achievement across a country; the Multidimensional Poverty Index (MPI) captures the depth/overlap of deprivations at the household level (health, education, living standards) — a country can show rising HDI while still carrying a large multidimensionally-poor population, a classic exam-trap distinction.

6. FUNDAMENTALS CHECK — CENSUS & SEX RATIO BASICS

Cue Words	Notes
Census of India — Basic Facts	Conducted decennially (every 10 years) since 1872 (first synchronous all-India census: 1881); Registrar General & Census Commissioner of India (Ministry of Home Affairs) is the nodal authority. Last conducted: 2011 — the 2021 Census was postponed (COVID-19) and is now scheduled as a digital-first exercise across 2026-27 (see Fact Sheet above).
Census 2011 — Baseline Figures	Population: ~121 crore. Sex Ratio: 943 females per 1,000 males (up from 933 in 2001). Child Sex Ratio (0-6 yrs): 919 (down from 927 in 2001) — the decline despite overall sex ratio improvement highlights persistent sex-selective practices.
Population Pyramid — Concept	A graphical (usually back-to-back bar chart) representation of a population's age-sex structure, with age cohorts on the vertical axis and population/percentage on the horizontal axis, split by sex. Its shape (expansive/stationary/constrictive — see Section 1) reveals a country's demographic-transition stage at a glance.

7. MIGRATION — LEGAL FRAMEWORK & INFORMATION SYSTEMS

Cue Words	Notes
Inter-State Migrant Workmen Act, 1979	Seeks to **regulate employment of inter-state migrants** and their conditions of service. **Principal employer prohibited** from employing inter-state workmen **without a certificate of registration** from state authorities. Applicable to **every establishment with more than 5 migrant workmen**. Establishment **cannot discriminate** against migrant workers with respect to **holidays, working hours, wages** etc. Subsumed into the **Labour Code on Occupational Safety, Health and Working Conditions** (one of the 13 laws replaced).
National Migrant Information System (NMIS)	**Online dashboard developed by NDMA**. Maintains a **central repository of migrant workers**; helps in **speedy inter-state communication** to facilitate smooth movement of migrant workers to their native places. Also helped in **contact tracing during COVID-19**.

8. NATIONAL ECONOMIC CENSUS & STATISTICAL MACHINERY

Cue Words	Notes
National Economic Census	A complete count of all establishments located within the geographical boundary of India. By MoSPI — 7th edition in 2019; first in 1977; not conducted at regular intervals. Conducted under the Collection of Statistics Act, 2008. Covers all households/establishments engaged in agriculture (excluding crop production and plantations) as well as non-agricultural economic activities including construction (except public administration, defence). For the 7th census, MoSPI partnered with CSC e-Governance Services — an SPV under MeitY — as implementing agency; for the first time the entire census was conducted on a digital platform using an app.
National Statistical Commission (NSC)	Set up as an **interim measure in 2005 by a notification** on the recommendation of the **Rangarajan Committee**; an **advisory body, not statutory**. **2019 Bill composition**: Chairman + **5 members**, **Deputy Governor of RBI**, **Chief Statistician of India**, **Chief Economic Advisor** (MoFinance); statistical audit; independent secretariat. **Powers/functions**: advice on legislative measures for official statistics; identify and evolve national policies and priorities; devise a **Code of Conduct**; statistical coordination between ministries/departments/agencies; act as **warehouse of core statistics**.
National Statistical Office (NSO)	Formed by merging CSO and NSSO; headed by the Secretary of MoSPI.
Periodic Labour Force Survey (PLFS)	By NSO, MoSPI; India's 1st computer-based survey; launched in 2017.

9. POPULATION HEALTH & DEPRIVATION METRICS

Cue Words	Notes
Disability Adjusted Life Years (DALY)	Expresses **premature mortality and disability**. Made up of — **Years of Life Lost (YLL)** (premature death before average life expectancy) + **Years of Life Lived with Disability (YLD)**. **DALY = YLL + YLD** — portrays the **total health loss** a person experiences during their life. **1 DALY = loss of 1 year of full health**.
Multidimensional Poverty Index (MPI) — Household Deprivation Indicators	**Health**: *Nutrition* — an adult under 70 years of age or a child is undernourished; *Child mortality* — any child under the age of 18 years has died in the five years preceding the survey. **Education**: *Years of schooling* — no household member aged 10 years or older has completed six years of schooling; *School attendance* — any school-aged child is not attending school up to the age at which he/she would complete class 8. **Standard of living**: *Cooking fuel* — household cooks with dung, wood, charcoal or coal; *Sanitation* — facility not improved (per SDG guidelines) or improved but shared; *Drinking water* — no access to improved drinking water (per SDG guidelines) or safe drinking water at least a 30-minute walk from home (round trip); *Electricity* — household has no electricity; *Housing* — materials for at least one of roof, walls and floor are inadequate (floor of natural material and/or roof/walls of natural or rudimentary materials); *Assets* — household does not own more than one of radio, TV, telephone, computer, animal cart, bicycle, motorbike or refrigerator, and does not own a car or truck.
HDR Family of Indices	The **Human Development Report** carries **5 indices** — **HDI**, **Inequality-Adjusted HDI (IHDI)**, **Gender Development Index (GDI)**, **Multidimensional Poverty Index (MPI)** and **Gender Inequality Index (GII)**. **HDI dimensions**: (1) *Health* — life expectancy at birth (min 20, India ~68.3, max 85 years); (2) *Knowledge* — mean years of schooling for those aged 25+ (min 0, India 6.3 yrs, max 15) and expected years of schooling (min 0, India 11.7 yrs, max 18); (3) *Standard of living* — GNI per capita (min 100, max 75,000). **Gender Development Index = Female HDI / Male HDI** — uses the same standards as HDI (Health, Education, Living Standards).
Mathew Effect	**Middle classes tend to be the main beneficiary** of social benefits and services targeted for the poor — "the rich get richer, the poor get poorer".
