Sadly this misses many details, Eastern Europe has many socialist workers buildings, with many apartments in one building.

In other regions are more villas because the wealth shifted immensely to the west during the reunion progress.

Many flats are in city districts became speculative assets for the rich. It’s more valuable to create one big Appartement out of two smaller ones.

In general Germany is densely urbanised leaving less room to build new houses with more space and forces companies to build more compact apartments.

It would be great to add the rough estimate of rent per square meter, to get a better view on regional popularity.

Please elaborate why this bothers you?

Well, I understand that you could believe this but this generally isn’t true.

Poor is always relative to the currency of the same country.

Maybe a poor person in the USA would be considers rich in South Asia or west africa. Bit the poor us Citizen neither works abroad nor can he afford to travel.

Also are there more criteria’s aside from income. Health systems, infrastructure, education.

While it is definitely true that the income per capita in USA is one of the highest, the USA lacks definitely at more than one of the other fields.
