How many people live in their own property?

Yes, and that is exactly the reason why the energy transition in the heating sector (insulation, conversion to heat pumps, etc.) is proceeding so slowly in Germany! - The incentives for landlords to invest in energy-saving measures are simply non-existent if increased heating costs (higher gas prices) can always be passed on to the tenants anyway...

There are compounding issues too:

Most cities, even more pronounced in Western Germany, have lackluster district heating networks — meaning green district heating concepts like in Denmark wouldn't work nearly as well.

There was a huge privatization wave in the 90s. Residential buildings in many cases now need to make a profit every year. High-capex measures that bring mediocre/hard-to-forecast opex improvements (entirely dependent on the price of fossil gas vs. electricity) like heat pumps are not going to win you fans among profit-driven investors.
That's just a wild guess. Switzerland is facing the same situation and yet, landlords are investing frenetically in the energy transition of their buildings to increase value. We're in a vicious circle of renovation and increasing rents where it has become an everyday struggle to afford rent. At least in thd cities.

Me: wait, what about England? …oh! Oh…..

The UK is still in Europe, but no longer in the EU

I don't understand why it's missed out here
- Especially since they included Switzerland, which was never in the EU.
  
  Norway and arguably Iceland should be included as well, and the Balkans. Norway would be same as Sweden, Iceland and Balkans no idea.

It seems like their is some misunderstanding of the map.
Here is the information that has been provided on Instagram for this post:

Being an owner or a tenant of your home is something that differs significantly among the Member States.

In the EU in 2021, 70 % of the population lived in a household owning their home, while the remaining 30 % lived in rented housing. The highest shares of ownership were observed in Romania (95 % of the population lived in a household owning their home), Slovakia (92 %, 2020 data), Hungary (92 %) and Croatia (91 %).

Of all the countries analysed, Switzerland and Germany were the only ones where renting was more common than owning.

FYI there's a duplicate sentence there:

In the EU in 2021, 70 % of the population lived in a household owning their home, while the remaining 30 % lived in rented housing.
- There are two kinds of people. Those who can extrapolate from incomplete data.

I know they are out of the club but maybe still interesting.

In England and Wales, the figure for 2021 was 62.5%, down from 64.3% in 2011 (~500k households fewer).

It's alright, I wouldn't see Turkey in the club either

I wonder if it plays a role in mid/eastern europe that many work in Germany etc and are then able to afford a house in their homecountries.

I would guess that property prices in big cities are just not as inflated as in central and western Europe.
It's just not common in Germany to buy apartments. People either rent, and if they want to buy, they buy a house. Most apartment buildings belong to big companies and not to smaller landlords, making it also not cheaper or in any way attractive to buy an apartment.

In Eastern Europe apartment ownership is very common on the other hand. All the old Soviet blocks have individual ownership of each apartment in it, and the buildings are maintained by groups of people who own the apartments in that building (I forgot the word, not a native English speaker, sorry. But basically like a union out of each owner in the building, there's monthly meetings to decide stuff etc). Landlords usually will not be big companies like in Germany, but just private persons who have had the apartment in their family for a long time. This also makes it easier to buy an apartment, if you don't want to rent.

It's just very different structures and mentalities. When I still lived in Germany I found it stupid to ever buy an apartment and would have just rented forever, since house prices are astronomical. Now I live in Eastern Europe and it took some time to adjust, but it's really just the norm here to buy or own an apartment at some point in your live and most natives I know here own one, or live in a place that a family member owns.
- Most people in Germany simply can't afford to buy an apartment, let alone a house.

  The word you're looking for is probably "cooperative"

Just for a comparison 65.9% for the USA. https://ipropertymanagement.com/research/homeownership-rate-by-state the worst states aren't under 50%.

the worst states aren't under 50%.

I wouldn't necessarily classify private home ownership as good or bad.

For one, there are different styles of living and if you need something small or need to move a bit more often, renting often makes more sense.

Then there's the more fundamental question if private home ownership actually means exactly that — in many cases, the home is basically still owned by the bank. The mortgage crisis hit really hard in countries with supposedly high home ownership like the US and Spain.
The homeownership rate declined in 82% of states between 2005 and 2020.
