Overview

  • This presentation analyzes three global development indicators:

    • GDP per capita (USD)
    • Life expectancy (years)
    • Education expenditure (% of GDP)

  • Data source: World Bank World Development Indicators (2022)

  • Objective: Understand economic and social development relationships.

Visualization observations

  • Countries with higher GDP per capita generally exhibit longer life expectancy, highlighting how income levels link to healthcare and living standards.

  • Small island nations like Kiribati, Tuvalu, and Vanuatu allocate over 10% of GDP to education — far above the global average of around 4%.

Highlights:

  • GDP per capita: Mean ≈ $21,175, wide income disparity

  • Life expectancy: Mean ≈ 73 years

  • Education expenditure: Mean ≈ 4.26%, up to 14.8%

Interpretation:

  • Countries with higher GDP per capita live longer on average.

  • Education investment varies more than income levels.

  • Some low-GDP nations still allocate significant education budgets.

  • Indicates that human capital can be prioritized even in smaller economies.\

Conclusion:

  • Economic prosperity and health outcomes are strongly correlated.

  • Both developing and developed nations invest in education, but levels differ widely.

  • Sustained investment in human capital is essential for inclusive growth.

  • Future work: Regional analysis and policy-based comparisons.
