Small-Scale Question Sunday for August 13, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Purchasing Power Parity is better IMO, constant USD 2017 might be a good option. The World bank usually has that. In this case it's basically the same as what you said: https://data.worldbank.org/indicator/NY.GDP.PCAP.PP.KD?locations=GB

It's a bit of an approximation (just what specifically makes up the 'basket of goods' that prices are compared for is open to manipulation) but all economic statistics are a kind of nonsense.

There was also the GFC in that period.
