📌 1. Population and Economic Development
| Indicator (Census 2011) | Value | Economic meaning |
|---|---|---|
| Total population | 121.09 crore | Large market and labour force, but pressure on resources |
| Decadal growth (2001–11) | 17.7% | Lowest growth since Independence |
| Density | 382 persons per sq km | Pressure on land, small holdings |
| Literacy | 74.04% | Quality of human capital |
| Sex ratio | 943 | Linked to female work participation and welfare |
- Malthus (1798): population grows geometrically and food arithmetically; checks are preventive (late marriage) and positive (famine, disease).
- Optimum population theory (Cannan): the size at which per capita income is highest — over- and under-population are relative ideas.
- Effects of rapid growth: lower per capita income, lower saving and investment, unemployment, strain on public services and the environment.
- National Population Policy 2000: immediate aim — unmet need for contraception; medium term — TFR to replacement level (2.1); long term — stable population by 2045.
- NFHS-5 (2019–21) put the national TFR at 2.0 — below replacement level.
⚠️ Exam Traps:
- Decadal growth fell in 2001–11, but the absolute addition (about 18 crore) was still very large.
- Optimum population is linked to Cannan, not Malthus.
📌 2. Demographic Transition and Dividend
| Stage | Birth rate / death rate | Growth |
|---|---|---|
| 1. High stationary | Both high | Very slow |
| 2. Early expanding | Birth rate high, death rate falls fast | Population explosion |
| 3. Late expanding | Birth rate also falls | Slowing |
| 4. Low stationary | Both low | Nearly stable |
- In India 1921 is called the "year of great divide" — population rose steadily after it.
- Dependency ratio = (0–14 plus over 65) ÷ (15–64) population; when it falls, the working-age share rises.
- The dividend pays only with education, skills, health and jobs; otherwise it can become a "demographic burden" (detail in Chapter 10).
- By UN estimates India became the world's most populous country in 2023.
⚠️ Exam Traps:
- The population explosion is in stage 2, when the death rate falls but the birth rate stays high.
📌 3. Economics of Infrastructure and Investment
- Economic infrastructure: energy, transport, communication, irrigation; social: education, health, housing, water and sanitation.
- Features: heavy and lumpy investment, long gestation, positive externalities, often natural monopoly.
- Infrastructure spending has a multiplier effect: demand rises during construction and production costs fall later (crowding-in).
- The Harmonised Master List (HML) has five categories: transport and logistics, energy, water and sanitation, communication, social and commercial infrastructure.
| Initiative | Year | Key point |
|---|---|---|
| National Infrastructure Pipeline (NIP) | 2019 | About ₹111 lakh crore of projects for 2020–25 |
| National Monetisation Pipeline (NMP) | 2021 | ₹6 lakh crore from existing public assets; ownership stays with the government |
| NIIF | 2015 | Quasi-sovereign infrastructure investment fund |
| NaBFID | 2021 | Development finance institution for long-term infrastructure lending |
| InvIT | 2014 (SEBI) | Trust that pays out income from completed projects |
⚠️ Exam Traps:
- Under monetisation (NMP) assets are not sold; only lease or operating rights are given — it differs from disinvestment.
📌 4. PPP Models
| Model | Arrangement | Risk |
|---|---|---|
| BOT (Build-Operate-Transfer) | Private party builds, operates and collects tolls, then transfers to the government | Traffic risk on the private party |
| BOOT | Private ownership too during the concession | On the private party |
| BOO | Ownership stays private; no transfer | On the private party |
| BOT-Annuity | Government pays a fixed annual sum | Traffic risk on the government |
| Hybrid Annuity (HAM) | Government pays 40% during construction, private party 60%, repaid as annuity | Shared |
| EPC | Government pays fully; contractor only builds | On the government |
| TOT (Toll-Operate-Transfer) | Built roads leased for tolling against an upfront payment | On the private party |
- Viability Gap Funding (VGF): capital grant for PPP projects that are economically justified but financially weak.
- The Kelkar Committee (2015) reviewed the PPP model and recommended fair risk sharing and a dispute-resolution mechanism.
💡 Memory Tip: HAM = 40 government : 60 private — "forty first, the rest in instalments".
📌 5. Energy, Transport, Communication and Logistics Policy
| Scheme | Sector | Economic aim |
|---|---|---|
| PM Gati Shakti (2021) | Multimodal infrastructure | Ministries plan on one GIS master plan, saving time and cost |
| National Logistics Policy (17 September 2022) | Logistics | Cut costs, improve LPI ranking; ULIP digital platform |
| Bharatmala | Roads | Economic corridors and border connectivity |
| Sagarmala | Ports | Port-led development, coastal shipping |
| Dedicated Freight Corridors | Rail | Faster, cheaper freight |
| UDAN (2016) | Regional air connectivity | Affordable flights through VGF |
| BharatNet | Communication | Broadband to gram panchayats |
- The LEADS index ranks states on logistics performance.
- Energy: electricity is on the Concurrent List; DISCOM losses are a major problem — reforms through UDAY (2015) and RDSS (2021).
- Rail freight is cheaper and cleaner than road; raising rail's share of freight is a policy aim.
⚠️ Exam Traps:
- Gati Shakti is a planning-coordination platform, not a funding scheme; ULIP is part of the National Logistics Policy.
