Subtopic 11.1: India's Demographic Significance in Global SDGs
Count people, not countries, and a large country becomes the swing vote on a global goal.
Starting point
Global SDG indicators are not a simple average of countries. They are weighted by people. A goal achieved in a small country and missed in a large one is mostly missed. India accounts for nearly one-sixth of the world population, about 18 percent in the way the notes round it. The assertion is that India’s success is critical for the global success of the goals. The reason is that population weight. Both are true, and the reason explains the assertion. That is the U.P. 2025 key.
The point is demographic arithmetic, not a compliment. If a large share of the world’s poor, or the world’s young people, or the world’s future emissions, sits in one country, the global total moves when that country moves. The same logic applies to China. The item is about India.
State the assertion: India’s SDG success is critical for the global result.
State the reason: nearly one-sixth of world population.
Mark both true, and mark the reason as the explanation.
Add the weighting: global indicators add people, not flags.
Do not answer with a GDP share unless the question asks for output. This reason is population.
Worked example. Imagine 100 people and a goal that 90 are in school. If 18 of the 100 live in one country and only half of them are in school, that country alone keeps the world well short of 90, no matter how perfect the small countries are. Scale that up and you have the assertion. The one-sixth is the weight. The explanation is not that India invented the goals. It is that India is large.
Memory hook. Both true, reason explains. India is about one-sixth of the world, so the global goal moves with India.
Further explanation
Population weights make India and China decisive for poverty, health and education totals, and increasingly for energy and emissions totals. A per-country index such as the SDSN rank treats India as one observation. A people-weighted global indicator treats India as a sixth of the observation. Both are published, and they answer different questions. The assertion-reason item is the people-weighted one.
“Nearly one-sixth” is the phrase to write. A more precise UN population share changes by the year. The item does not require a decimal.
Figure
Why the weight is the explanation
Global SDG totals are population-weighted
India ≈ one-sixth of world population
Therefore India’s domestic result moves the global result
The assertion-reason key is that both statements are true and the population statement explains the first.
The report’s rankings chapter records India gaining 18 places and 9.6 index points since 2015. Older exam questions use earlier editions (2016, 2017, 2023) and those ranks are kept in the question bank, not overwritten by this vintage.
Concept
Original notes
Subtopic 11.1: India's Demographic Significance in Global SDGs
The realization of the 2030 Agenda for Sustainable Development depends substantially on the performance of high-population developing economies. India accounts for approximately 17.5% to 18% (nearly one-sixth) of the entire human population.
Because core SDG indicators—such as ending extreme poverty, eliminating malnutrition, improving maternal health, expanding sanitation, and providing clean cooking energy—are population-weighted aggregates, global targets cannot be met mathematically without decisive progress in India. India's progress directly determines worldwide SDG performance.
Important points
India represents nearly one-sixth (around 18%) of the total world population.
Global SDG indicators are population-weighted aggregates.
India's domestic success is indispensable for the global success of Agenda 2030.

Original question
Question 20: Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R): Assertion (A): India's success is critical for the global success of Sustainable Development Goals. Reason (R): India accounts for nearly one-sixth of the total world population. Select the correct answer: [U.P. P.C.S. (Pre) 2025]
Both (A) and (R) are true, and Reason (R) correctly explains Assertion (A) because global SDG progress is mathematically population-weighted.
