1. Shift from Income to Human Development (basic)
For a long time, the world measured a country’s progress by a single yardstick: Economic Growth. The logic was simple—if the National Income or Gross Domestic Product (GDP) increased, it was assumed that the quality of life for its citizens would naturally follow. However, this “Income Approach” had a major flaw: it ignored how that wealth was distributed and whether people actually had the freedom to use that wealth to improve their lives. The shift from an Income-centric to a Human-centric view of development marks one of the most significant evolutions in modern economics.
This paradigm shift was spearheaded in the 1990s by two visionary South Asian economists and close friends: Dr. Mahbub-ul-Haq and Prof. Amartya Sen. Dr. Haq argued that development is not about the expansion of inanimate objects (like machines or money), but about enlarging people’s choices. In his view, the basic goal of development is to create an environment where people can enjoy long, healthy, and creative lives Fundamentals of Human Geography, Class XII (NCERT 2025 ed.), Chapter 3, p.14. This philosophy led to the creation of the first Human Development Report by the UNDP in 1990.
To understand this shift deeply, we must look at Amartya Sen’s Capability Approach. Sen proposed that poverty is not just a lack of money, but a “capability deprivation.” Even if a person has a decent income, they may still be “poor” if they lack access to clean water, quality healthcare, or education, as these services cannot always be purchased individually in a market Indian Economy, Vivek Singh (7th ed.), Inclusive growth and issues, p.278. Development, therefore, is the process of expanding human capabilities—giving people the freedom to lead the kind of life they have reason to value Indian Economy, Nitin Singhania (2nd ed.), Poverty, Inequality and Unemployment, p.41.

2. The Human Development Index (HDI) Pillars (basic)
To truly understand the Human Development Index (HDI), we must first look at its philosophy. Before the 1990s, a country's progress was judged almost entirely by its Economic Growth (GDP). However, visionary economists like Mahbub-ul-Haq and Amartya Sen argued that the real purpose of development is to enlarge people's choices and improve their lives. This led the United Nations Development Programme (UNDP) to adopt the HDI as a summary measure of human progress Indian Economy, Vivek Singh (7th ed. 2023-24), Inclusive growth and issues, p.282.
The HDI is built upon three fundamental pillars (or dimensions). Each dimension is measured using specific indicators to provide a standardized score between 0 and 1. The closer a country is to 1, the higher its level of human development Fundamentals of Human Geography, Class XII (NCERT 2025 ed.), Chapter 3: Human Development, p.17.
| Dimension |
Indicator(s) Used |
What it tells us |
| Long and Healthy Life |
Life Expectancy at Birth |
Reflects the quality of healthcare, nutrition, and environmental safety. |
| Knowledge (Education) |
1. Expected Years of Schooling 2. Mean Years of Schooling |
Measures the access to education for children and the actual attainment of adults. |
| Decent Standard of Living |
GNI per capita (PPP $) |
Shows the purchasing power of citizens, adjusted for international price differences. |
The final HDI score is the geometric mean of the indices for these three dimensions. Based on this score, countries are grouped into four categories: Very High (0.800+), High (0.700–0.799), Medium (0.550–0.699), and Low (below 0.550). Interestingly, while income is included, the HDI reminds us that a high national income does not automatically guarantee high health or education levels Indian Economy, Nitin Singhania (ed 2nd 2021-22), Economic Growth versus Economic Development, p.25.
Remember The 3 Pillars of HDI are H.E.L.: Health (Life Expectancy), Education (Schooling years), and Living Standard (GNI per capita).
Key Takeaway The HDI shifts the focus from purely economic metrics to human-centric ones by combining health, education, and purchasing power into a single composite score.

3. India's Poverty Estimation Committees (intermediate)
In India, defining the Poverty Line has been a journey of moving from a simple survival mindset to a more holistic view of human dignity. Historically, poverty was calculated based on caloric intake—essentially asking, "Does this person have enough money to buy enough food to survive?" However, over the last two decades, two major committees have redefined this approach, acknowledging that a human being needs more than just calories to thrive: they need health, education, and basic amenities.
The Tendulkar Committee (2009) marked a paradigm shift. It moved away from a calorie-centric model to a cost-of-living approach, incorporating private expenditure on health and education into the poverty basket. It also introduced the Mixed Reference Period (MRP), which tracks consumption over different timeframes (e.g., 30 days for food and 365 days for clothing). Later, the Rangarajan Committee (2014) sought to refine this even further. While Tendulkar focused on calories alone for nutrition, Rangarajan expanded the nutritional requirement to include proteins and fats, using a more precise Modified Mixed Reference Period (MMRP) for data collection Nitin Singhania, Poverty, Inequality and Unemployment, p.40.

Currently, the official status of these estimates is in a bit of a transition. The government tasked the NITI Aayog to define a new poverty line. While a final new line is still under deliberation, the NITI Aayog has informally supported the Tendulkar Committee estimates for its calculations Vivek Singh, Inclusive growth and issues, p.256. This is vital for us to understand because these committees don't just produce numbers; they determine who is eligible for government welfare schemes and subsidies, impacting millions of lives.

2009 — Tendulkar Committee: Included health and education; shifted to MRP.
2014 — Rangarajan Committee: Included proteins/fats; shifted to MMRP.
Key Takeaway India's poverty estimation has evolved from a narrow "calorie-only" focus to a broader "expenditure-based" approach that includes health, education, and refined nutritional standards.

4. The Global Multidimensional Poverty Index (MPI) (intermediate)
While traditional poverty measures often focus solely on income (e.g., living on less than $2.15 a day), the Global Multidimensional Poverty Index (MPI) recognizes that poverty is more complex. Launched in 2010 by the UNDP and the Oxford Poverty and Human Development Initiative (OPHI), the MPI measures the actual deprivations people face in their daily lives. It replaced the older Human Poverty Index (HPI) to provide a more comprehensive picture of human development Indian Economy, Vivek Singh, Inclusive growth and issues, p.282.
The Global MPI is built upon three equally weighted dimensions, which are further broken down into 10 indicators. To be classified as "multidimensionally poor," an individual must be deprived in at least one-third (33.3%) of the weighted indicators. These indicators are:
- Health: Nutrition and Child Mortality.
- Education: Years of Schooling and School Attendance.
- Standard of Living: Cooking fuel, Sanitation, Drinking water, Electricity, Housing, and Assets.
In the Indian context, the MPI has become a critical tool for policy. While the Global MPI uses 10 indicators, India's NITI Aayog developed a National Multidimensional Poverty Index (NMPI) which adds two more indicators—Maternal Health and Bank Accounts—bringing the total to 12 indicators to better reflect local priorities Economics Class IX, Poverty as a Challenge, p.33. India has shown significant progress in recent years; for instance, the 2020 report noted a headcount ratio of approximately 27.91% Indian Economy, Nitin Singhania, Poverty, Inequality and Unemployment, p.36.
Key Takeaway The MPI captures how people are poor by measuring deprivations across health, education, and living standards, moving beyond mere monetary income to identify the overlapping struggles a person faces simultaneously.

5. Gender and Inequality Indices (intermediate)
When we talk about development, looking at averages can be misleading. A country might have a high average income, but if most of that wealth is held by men while women are excluded, the 'human development' is incomplete. This brings us to
Gender and Inequality Indices, which move beyond simple averages to look at the gaps between different groups. In sociology and economics, we distinguish
gender (the unequal roles assigned by society) from
biological sex Democratic Politics-II. Political Science-Class X . NCERT(Revised ed 2025), Gender, Religion and Caste, p.44. To measure these societal gaps, the UNDP and other international bodies use specific composite tools.
The most prominent tool is the
Gender Inequality Index (GII), introduced by the UNDP in 2010. Unlike the standard HDI which measures achievements, the GII measures the
loss of accomplishment within a nation due to gender inequality. It uses three critical dimensions:
Reproductive Health (measured by maternal mortality and adolescent birth rates),
Empowerment (measured by the share of parliamentary seats and attainment in secondary education), and the
Labour Market (measured by participation rates)
Indian Economy, Nitin Singhania, Economic Growth versus Economic Development, p.26. A higher GII value indicates more inequality and thus a greater loss to human development.
While the GII looks at inequality as a loss, the
Gender Development Index (GDI) measures the ratio of female-to-male HDI values. It effectively shows how far women are lagging behind men in the basic dimensions of health, knowledge, and living standards
Indian Economy, Nitin Singhania, Economic Growth versus Economic Development, p.26. Additionally, the World Economic Forum publishes the
Global Gender Gap Index (GGGI), which evaluates gender parity across four pillars: economic participation, educational attainment, health and survival, and political empowerment
Indian Economy, Nitin Singhania, Economic Growth versus Economic Development, p.29.
Apart from gender, we also measure inequality through
deprivation using the
Human Poverty Index (HPI). This index is unique because it is a
non-income measure. Instead of looking at what people have (income), it looks at what they lack in three areas: longevity (probability of not surviving to age 40), knowledge (adult illiteracy rate), and a decent standard of living (access to safe water and health services, and nutrition levels in children)

Key Takeaway
Gender and inequality indices shift the focus from "how much has a country achieved?" to "who is being left behind?", measuring the cost of inequality in terms of lost human potential.

6. The Human Poverty Index (HPI-1 vs HPI-2) (exam-level)
While the Human Development Index (HDI) measures the average achievements of a country, it doesn't tell us how many people are being left behind. To address this, the UNDP introduced the Human Poverty Index (HPI) in 1997. If the HDI is the "glass half-full" (attainments), the HPI is the "glass half-empty" (deprivations). It focuses on the shortfalls in the same three basic dimensions as the HDI: longevity, knowledge, and a decent standard of living Fundamentals of Human Geography, NCERT, Chapter 3, p.17.
The HPI is a non-income measure of poverty, designed to show that poverty is more than just a lack of money—it is a lack of opportunity and choice. However, because the nature of poverty differs between the "Global South" and the "Global North," the UNDP created two separate versions: HPI-1 for developing countries and HPI-2 for select high-income OECD countries.
| Dimension |
HPI-1 (Developing Countries) |
HPI-2 (Developed Countries) |
| Longevity |
Probability at birth of not surviving to age 40. |
Probability at birth of not surviving to age 60. |
| Knowledge |
Adult illiteracy rate (lack of basic reading/writing). |
Functional illiteracy rate (lack of skills to function in modern society). |
| Standard of Living |
Measured by lack of access to safe water and the percentage of underweight children. |
Income deprivation: Population living below 50% of the median adjusted household disposable income. |
| Social Exclusion |
Not explicitly measured. |
Long-term unemployment rate (unemployed for 12 months or more). |
A key takeaway here is the inclusion of Social Exclusion in HPI-2. In developed nations, poverty isn't just about physical survival; it's about being marginalized from the community. Long-term unemployment is used as a proxy for this because it often leads to a loss of self-esteem and social ties Indian Economy, Nitin Singhania, Poverty, Inequality and Unemployment, p.51. By comparing these two indices, we see that as a country grows wealthier, the "yardstick" for what constitutes poverty shifts from basic survival to social participation.
Key Takeaway The Human Poverty Index measures deprivations; HPI-1 focuses on basic survival and health in developing nations, while HPI-2 includes social exclusion and relative income poverty for developed nations.

7. Solving the Original PYQ (exam-level)
In your previous lessons, you explored how Human Development shifted the focus from purely economic growth to the quality of human life. The Human Poverty Index (HPI), introduced by the UNDP in 1997, is essentially the "mirror image" of the HDI; while the HDI measures progress, the HPI measures deprivation in those same fundamental areas: longevity, knowledge, and a decent standard of living. This question tests your ability to map specific indicators to these broad dimensions. As you analyze the statements, remember that Literacy deprivation (Statement 2) maps directly to the lack of knowledge (adult illiteracy rate), and Social services deprivation (Statement 3) reflects a lack of a decent standard of living, specifically access to safe water and health services as noted in FUNDAMENTALS OF HUMAN GEOGRAPHY, CLASS XII (NCERT 2025 ed.).
To arrive at the correct answer (B), you must navigate a common UPSC nuance regarding Income deprivation (Statement 1) and Employment deprivation (Statement 4). While the HPI is often distinguished as a "non-income" measure, its variant for developed countries (HPI-2) explicitly includes the income poverty line to capture standard of living gaps. However, long-term unemployment is a highly specific indicator used only in the HPI-2 framework to represent social exclusion, rather than a primary pillar of the general HPI framework. UPSC often uses "Employment" as a distractor because students tend to associate it with general poverty, but in the context of the HPI's structural dimensions—longevity, knowledge, and living standards—it is the first three deprivations that form the core conceptual base for this index.
