Question

What is the suitable measure for the comparison of development between two or more countries?

Answer 1

The most basic comparison is between GDP per capita levels or the levels of GDP per capita in terms of Purchasing Power Parity. However, GDP can sometimes be a misleading measure as it may not capture many other aspects of the quality of life, such as crime, education, environmental quality, etc. The Human Development Index published by the UN is a composite measure that accounts for a broader set of development factors.
