In order to make international comparisons of development what adjustments is made to GDP or GNU?

To make international comparisons of development, Gross Domestic Product (GDP) or Gross National Income (GNI) are often adjusted for purchasing power parity (PPP). This adjustment accounts for differences in price levels across countries, allowing for a more accurate comparison of living standards and economic output. Additionally, per capita measures are frequently used to assess the average income or economic well-being of individuals within different nations. These adjustments help to provide a clearer picture of relative development across diverse economies.
