It said that your nation has a nominal GDP per capita of 48,000 but a PPP (Purchasing Power Parity) of 65,000 or around that figure.
In laymen's term (although not always), countries with lower nominal GDP per capita than their PPP are usually developing and underdeveloping economies such as most real life southeast asian and african nations.
A nominal GDP per capita represents the total economic output of your nation, while PPP represents your economic output after being compared to the rest of the world's economies.
A lower Nominal GDP per capita than PPP (an in this case it is a huge difference) means that things are much cheaper in your nation, which means that your currency must be valued at a really, really low worth, which is the major characteristic of a developing and third world economies (although in exceptional circumstance such as Japan it is not the case).
Edit : Which bring us to the main point. The "prosperous situation" of your private sectors will not bring your Nominal GDP per capita down (which is the case here), and instead should've bring it up slightly or more than above your PPP (Purchasing Power Parity).
PPP (Purchasing Power Parity) and Nominal GDP per capita has a meaning behind it, and it is not recommendable to throw in random numbers as it lead to unrealistic economic output and expectation. I guess, that is one of the most major mistakes made by NS'ers these days, together with the funny claim of things such as "I have no Public or Government Debt", which is impossible unless your nation is like Zimbabwe, North Korea, and the likes of the impoverished and/or stagnant low income nations.
