Answer by Daa-yum
Real GDP per capita (= GDP per capita PPP) tells you way more than nominal GDP per capita, because it takes into consideration the differences between purchasing power. Purchasing power means that in some countries you gotta pay $ 1.20 for a bottle of water, in others you have to pay only $ 1.00. So less money is worth more in the second country. GDP at PPP is nominal GDP adjusted for these differences. That being said GDP per capita (PPP) and HDI remain. Well, HDI mostly measures how educated and healthy people are, but it also takes GDP into account. It's kind of subjective which measure is better, it depends on your own preferences and priorities. But most of the time countries with a high GDP per capita also have a high HDI. I personally would prefer GDP per capita (PPP).
