Economic Development Measured by Income Levels

Steps:

• Recall that developed countries are defined by high levels of economic prosperity and living standards.
• Identify key indicators: GDP per capita, real incomes, and human development index.
• Compare options to standard metrics: focus on those directly linked to development status.
• Select the option aligning with higher real incomes as the hallmark of development.

Why D is correct:

• Developed countries are characterized by higher real GDP per capita, reflecting greater economic output and purchasing power per person, per World Bank and UN definitions.

Why the others are wrong:

• A: Interest rates vary by monetary policy and are often lower in developed countries to stimulate growth.
• B: Natural resources abundance does not correlate with development; many resource-rich nations remain less developed due to poor management.
• C: Inflation is typically lower and more stable in developed countries, not higher.

Final answer: D
