The HDI is used by policymakers to:

Track progress over time
Identify areas for improvement
Compare performance with other regions
All of the above

The correct answer is: D) All of the above

The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores higher on the HDI if it has a higher life expectancy, higher education attainment, and higher per capita income.

The HDI is used by policymakers to track progress over time, identify areas for improvement, and compare performance with other regions.

  • Track progress over time: The HDI can be used to track progress over time by comparing a country’s HDI score from one year to the next. This can help policymakers identify areas where progress is being made and areas where more needs to be done.
  • Identify areas for improvement: The HDI can also be used to identify areas for improvement by comparing a country’s HDI score to the scores of other countries. This can help policymakers identify areas where a country is lagging behind and focus resources on those areas.
  • Compare performance with other regions: The HDI can also be used to compare performance with other regions by comparing a country’s HDI score to the scores of other countries in the same region. This can help policymakers identify best practices and learn from the experiences of other countries.
