Which indicators distinguish developed from developing countries, and what indicators distinguish them?

• A. Developed countries have high income, advanced infrastructure, and longer life expectancy; indicators include HDI, GDP per capita, and life expectancy.
• B. They are distinguished by population size.
• C. They are distinguished by climate.
• D. They are distinguished by the number of natural resources.

Answer: (A)

Indicators of development focus on wealth, infrastructure, and health. In developed countries, income is high, infrastructure is advanced, and life expectancy is longer. The key measures people use are the Human Development Index, which combines life expectancy, education, and standard of living; GDP per capita, which shows average income per person; and life expectancy at birth, which reflects health and overall living conditions. Taken together, these indicators show why developed nations differ from developing ones: they point to sustained wealth, reliable services, and healthier populations. Other factors like population size, climate, or the number of natural resources don’t reliably separate development levels, since these can vary independently from development status.
