Read the below statements marked as Assertion (A) and Reason (R). Mark the correct options: Assertion (A): Human Development Index (HDI) in India improved significantly post-2010. Reason (R): The methodology was revised globally to include inequality-adjusted Human Development Index (HDI).
- (a)Both A and R are true, and R is the correct explanation of A.
- (b)Both A and R are true, but R is not the correct explanation of A.
- (c)A is true, but R is false.
- (d)A is false, but R is true.
Answer
Why
Correct — B. A is true. UNDP's series puts India's HDI at 0.590 in 2010 and 0.685 in 2023 (Human Development Report 2025).
R is true as a description of the 2010 Human Development Report, which revised the HDI's method and introduced the inequality-adjusted HDI (IHDI).
R does not explain A. The IHDI is a separate index that discounts the HDI for inequality, so it cannot lift India's HDI. The HDI rises through its components: life expectancy, schooling and income. So option (b).
Why the others are wrong
- (a)Both A and R are true, and R is the correct explanation of A. — A change of method cannot explain a real rise. The IHDI sits beside the HDI and only discounts it for inequality, so R gives no reason why India's HDI went up.
- (c)A is true, but R is false. — R is true: the 2010 Human Development Report did revise the HDI's method and introduced the IHDI. Marking R false misreads a documented change.
- (d)A is false, but R is true. — A is true: on UNDP's own series India's HDI rose from 0.590 in 2010 to 0.685 in 2023, so 'A is false' cannot stand.
Concept
The Human Development Index combines three dimensions: a long and healthy life (life expectancy at birth), knowledge (mean and expected years of schooling) and a decent standard of living (GNI per capita, PPP).
The 2010 report changed the method: schooling years replaced literacy and enrolment, GNI replaced GDP, and the three indices are now combined by a geometric mean.
It also launched the IHDI, the HDI discounted for inequality in each dimension.
R is loosely worded: the IHDI was added beside the HDI, not built into it. The key still reads R as true, as a description of the 2010 revision.
Key facts
- HDI dimensions: life expectancy at birth, mean and expected years of schooling, and GNI per capita (PPP).
- The 2010 Human Development Report introduced the inequality-adjusted HDI (IHDI) and a new method for the HDI.
- Since 2010 the HDI is the geometric mean of its three dimension indices.
- Human Development Report 2025: India's HDI is 0.685 for 2023, rank 130.

Common traps
- Linking a new formula to a rising score, when UNDP publishes India's HDI as one consistent series from 1990.
- Marking R false because the IHDI is a separate index, when the key reads R as a description of the 2010 revision.
Here the Assertion-Reason frame pairs two true statements that are not cause and effect.
The HDI's workings are also asked at 20 Sep 2025, 12:30, GA Q.20 (whether it can rise while income falls, keyed (a)) and Tier-II Paper-I, 19 Jan 2026, 11:00, GA Q.13 (the knowledge indicators, keyed mean and expected years of schooling).
