General Certificate of Secondary Education (GCSE) Geography Paper 2 Practice Exam

The Human Development Index (HDI) combines GDP per capita, life expectancy, and adult literacy to provide a composite measure of human development. GDP per capita reflects the average economic output per person, which indicates the standard of living within a country. Life expectancy is a key indicator of health and longevity, signifying the overall well-being of a population. Adult literacy represents the educational attainment and knowledge level of the population, which is essential for personal and societal development. By combining these three critical dimensions, the HDI offers a comprehensive insight into the quality of life and development status of a country, rather than just focusing solely on economic measures.

The other options do not encompass the complete or correct combination of indicators used in the HDI. For instance, population density and infant mortality are important metrics, but they are not part of the HDI framework. Similarly, while employment rates and average income may provide economic insight, they do not capture the educational and health aspects emphasized by the HDI.
