NDA Geography · Indian Geography — Economy, Resources and Transport
Economic Sectors and Government Schemes
The five tiers of economic activity, India's flagship development schemes, and the census-and-demography facts that recur every year.
Why this matters
Around 15 PYQs once the demography questions misfiled elsewhere are folded in, with a HARD streak in the Census-2011 ranking questions. Three things pay: the primary-to-quinary activity ladder (quaternary = knowledge work, quinary = top decision-making), the named schemes (Bharatmala, classification of resources), and the Census-2011 superlatives (least-populated state, lowest density, negative-growth state). The census rankings are pure memorisation — drill the extremes.
Concept 1 of 4
Primary to quinary — the tiers of economic activity
Intuition
Definition
- Primary — extraction from nature: agriculture, mining, fishing, forestry.
- Secondary — manufacturing and construction.
- Tertiary — services: trade, transport, banking, education.
- Quaternary — knowledge/information activities: research, R&D, creation, rearrangement and interpretation of new and existing ideas.
- Quinary — the highest decision-making: top executives, senior officials, lawmakers.
Worked example
- Idea-creation and interpretation is knowledge work, not direct service delivery.
- Tertiary is ordinary services; quinary is top decision-making.
- Knowledge/information work is the quaternary tier.

Concept 2 of 4
Flagship schemes and resource classification
Intuition
Definition
- Bharatmala Pariyojana / Project — a programme to build and improve National Highways (road connectivity), NOT river-linking or rail.
- Classification of resources — basic inexhaustible → solar energy; conventional non-renewable → coal; non-conventional renewable → hydel power; non-conventional non-renewable → natural gas.
- National Water Academy — water-resource training centre at Pune.
- Indian Academy of Highway Engineers — a registered society (statement 1 correct), but the second claim about it being a Centre+State collaborative body is the wrong clause.
| Scheme / item | What it is |
|---|---|
| Bharatmala | National Highways network programme NDA 2021 — Bharatmala = networks of National Highways. |
| Solar energy | Basic inexhaustible resource |
| Coal | Conventional non-renewable resource |
| National Water Academy | Pune (water-resource training) |

Concept 3 of 4
Census 2011 — population superlatives
Intuition
Definition
- Lowest population density (2011) — Sikkim (among small states/UTs listed).
- Negative population growth (2001–11) — Nagaland (the only major state to record a decline).
- Sex ratio (NE states, descending) — Meghalaya > Manipur > Mizoram > Tripura.
- Highest female literacy among UTs — Lakshadweep.
- Indian languages fall into chiefly two major language families (Indo-Aryan and Dravidian).
| Superlative | Answer |
|---|---|
| Lowest population density | Sikkim NDA 2017 — lowest density among the listed states. |
| Negative population growth (2001–11) | Nagaland NDA 2018 (Sep) — only Nagaland recorded a decline. |
| Highest female literacy (UT) | Lakshadweep |
| Major language families | Two (chiefly) |

Memorise the extremes, not the full order
Concept 4 of 4
Trade partners, tribes and ordered geography
Intuition
Definition
- Largest trading partner (2015-16) — USA.
- Tribe-state pairs — Adi = Arunachal Pradesh, Irula = south India, Shaharia = Rajasthan. Tharu : Madhya Pradesh is WRONG (Tharu live in the UP/Uttarakhand terai).
- Tiger reserves, north → south — Corbett → Sariska → Simlipal → Periyar.
| Item | Fact |
|---|---|
| Largest trading partner 2015-16 | USA |
| Tharu : Madhya Pradesh | WRONG pair (Tharu = UP/Uttarakhand terai) NDA 2017 — Tharu : Madhya Pradesh is the incorrectly-matched pair. |
| Tiger reserves N→S | Corbett → Sariska → Simlipal → Periyar NDA 2017 — correct north-to-south order. |
