Difficulty: MediumIndicators and Measurement of Economic Development

Match each economic development indicator on the left with its correct defining components or primary measurement purpose on the right.

  • Human Development Index (HDI)A composite measure combining life expectancy at birth, mean/expected years of schooling, and per capita gross national income.
  • Physical Quality of Life Index (PQLI)A non-monetary composite index measuring basic literacy rate, infant mortality rate, and life expectancy at age one.
  • Real Per Capita IncomeA quantitative metric computed by dividing inflation-adjusted Gross Domestic Product by total population size.
  • Gini CoefficientMeasures income inequality within a country, taking values between 0 (perfect equality) and 1 (perfect inequality).

Answer

Human Development Index (HDI) matches with the composite measure of life expectancy, schooling, and per capita GNI. Physical Quality of Life Index (PQLI) matches with the non-monetary measure of literacy rate, infant mortality rate, and life expectancy at age one. Real Per Capita Income matches with the quantitative metric dividing inflation-adjusted GDP by population. Gini Coefficient matches with the measurement of income inequality ranging from 0 to 1.
Each indicator is accurately matched with its core components and economic definition: Human Development Index incorporates life expectancy, schooling, and per capita GNI; Physical Quality of Life Index combines literacy, infant mortality, and life expectancy at age one; Real Per Capita Income represents inflation-adjusted GDP divided by total population; and the Gini Coefficient measures income inequality on a scale from 0 to 1.

Step-by-Step Solution

1
Identify the composition of Human Development Index (HDI).
HDI incorporates three key dimensions: health (life expectancy), education (schooling years), and command over resources (GNI per capita).
HDI is a holistic socio-economic development indicator designed by the United Nations Development Programme.
2
Identify the components of Physical Quality of Life Index (PQLI).
PQLI focuses purely on non-monetary social welfare metrics: literacy rate, infant mortality rate, and life expectancy at age one.
PQLI was created to evaluate quality of life without relying on national income figures.
3
Define Real Per Capita Income calculation and purpose.
Real Per Capita Income equals Real GDP divided by population.
Adjusting nominal output for price changes (inflation) isolates actual changes in average individual purchasing power.
4
Define the purpose of the Gini Coefficient.
Gini Coefficient quantifies income distribution inequality derived from the Lorenz curve.
Values closer to 0 reflect equal distribution, while values closer to 1 signify severe income inequality.
