How does the Human Development Index (HDI) vary across different countries?

The Human Development Index (HDI) varies across different countries based on several factors.

Firstly, the HDI takes into account three dimensions of human development: health, education, and income. Therefore, countries with higher life expectancy, higher literacy rates, and higher per capita income tend to have higher HDI scores. On the other hand, countries with lower life expectancy, lower literacy rates, and lower per capita income tend to have lower HDI scores.

Secondly, the HDI also considers the inequality within a country. It takes into account the distribution of income and education within a country, which means that countries with more equal distribution of resources tend to have higher HDI scores compared to countries with high levels of inequality.

Thirdly, the HDI is influenced by the level of economic development in a country. Developed countries with advanced infrastructure, technology, and industries tend to have higher HDI scores compared to developing or underdeveloped countries with limited resources and infrastructure.

Additionally, the HDI can vary across different countries due to cultural, social, and political factors. Factors such as gender equality, access to healthcare and education, political stability, and social inclusion can impact a country's HDI score.

Overall, the Human Development Index varies across different countries based on their levels of health, education, income, inequality, economic development, and various socio-cultural factors.
