# Population, urbanization & settlements

India's demographic transition, Census 2011 population data, urbanization patterns, and rural settlement types for UPSC Prelims and Mains GS-1.

## India's Population: The Numbers That Anchor the Topic

The Census of India, conducted under the Census Act, 1948, and the decennial Census Rules, 1990, is the constitutional bedrock of population study. Census 2011 recorded India's population at **1,210.85 million** (1.21 billion), growing at a decadal rate of **17.7%** (2001-2011), the lowest since independence. The sex ratio stood at **943 females per 1,000 males**, the highest since 1971, while the **child sex ratio (0-6 years) fell to 919**, the lowest since independence and a recurring Prelims fact. Literacy reached **74.04%** (male 82.14%, female 65.46%), with Kerala highest (93.91%) and Bihar lowest (63.82%). Population density was **382 persons/sq km**; Bihar was the densest state (1,106) and Arunachal Pradesh the sparsest (17).

## The Demographic Transition Model

The Demographic Transition Model (DTM), formalized by Warren Thompson (1929) and Frank Notestein (1945), explains population change in four (sometimes five) stages: high stationary (high birth and death rates), early expanding (death rate falls), late expanding (birth rate falls), and low stationary (both low). India is decisively in **Stage 3**: the Crude Death Rate (CDR) has dropped to about 6 per 1,000, while the Crude Birth Rate (CBR) is around 19-20 per 1,000 (Sample Registration System, RGI). The **Total Fertility Rate (TFR)** fell to **2.0** per NFHS-5 (2019-21), below the replacement level of 2.1 for the first time, signaling that India will stabilize in coming decades.

## The Demographic Dividend

The **demographic dividend**, a term popularized by David Bloom and Jeffrey Williamson, refers to the growth potential when the working-age population (15-59) outnumbers dependants. The **Economic Survey 2018-19** projected India's working-age share peaking around **2041**, with the dependency ratio bottoming out. India's median age (\~28 years) makes it the youngest large economy. Yet the dividend is conditional: it materializes only with adequate education, skilling (Skill India, 2015), health, and job creation. States diverge sharply: peninsular states (Kerala, Tamil Nadu, Andhra Pradesh) have already aged demographically, while the **EAG states** (Empowered Action Group: Bihar, UP, MP, Rajasthan, Jharkhand, Chhattisgarh, Odisha, Uttarakhand) still have high fertility and will supply the future workforce.

The **National Population Policy, 2000**, set the long-term goal of stable population by 2045, consistent with sustainable economic growth. Migration is the fourth demographic process after fertility, mortality and natality: Census 2011 recorded over **450 million internal migrants**, predominantly female and marriage-driven, but with rising male labour migration from the Hindi belt to Maharashtra, Delhi, Gujarat and Kerala. Push factors (rural distress, fragmented holdings) and pull factors (urban wages, services) structure these flows, vividly exposed during the 2020 reverse-migration during the COVID-19 lockdown.
