Measuring Human Development

The Human Development Index (HDI) ranks countries based on their performance in three key areas: health, education, and access to resources. Each country receives a score between 0 and 1, and the closer the score is to 1, the higher the level of human development. A score of 0.983 is considered very high, while 0.268 indicates a very low level.

The three dimensions are measured using specific indicators. Health is assessed by life expectancy at birth — a higher life expectancy means people have a greater chance of living longer and healthier lives. Education is measured through adult literacy rate and gross enrolment ratio; these show how easy or difficult it is to access knowledge in a country. Access to resources is measured in terms of purchasing power (in US dollars). Each of these three dimensions is given equal weight — one-third each. The HDI is the sum total of these weighted scores.

The Human Poverty Index (HPI) is related to the HDI but measures the shortfall in human development. It is a non-income measure that looks at:

• The probability of not surviving till age 40
• The adult illiteracy rate
• The number of people without access to clean water
• The number of small children who are underweight

Often, the HPI is more revealing than the HDI. Looking at both indices together gives an accurate picture of human development in a country.

Four Approaches to Human Development

The textbook describes four distinct approaches that have shaped how human development is understood and measured.

Income Approach — This is one of the oldest approaches. It links human development directly to income, arguing that the level of income reflects the level of freedom an individual enjoys. Higher income means higher human development.

Welfare Approach — Here, human beings are seen as beneficiaries or targets of development activities. The government is responsible for increasing human development by maximising expenditure on education, health, social services, and amenities. People are passive recipients, not active participants.

Basic Needs Approach — Initially proposed by the International Labour Organisation (ILO), this approach identifies six basic needs: health, education, food, water supply, sanitation, and housing. It focuses on providing these needs to defined sections of society but ignores the question of human choices.

Capability Approach — Associated with Professor Amartya Sen, this approach argues that building human capabilities in health, education, and access to resources is the key to increasing human development. It shifts the focus from what people have to what they are able to do and be.

Refining Measurement and Broader Links

The ways to measure human development are constantly being refined. Researchers have found links between human development and factors like the level of corruption or political freedom in a region. There is discussion about creating a political freedom index and a listing of the most corrupt countries. …
