Another point I'd like to add is the US isn't far from Switzerland on that list. Also Singapore being in the #2 spot with 90% home ownership, but in my opinion Singapore is considered a wealthy country[1] with a GDP close to the US.
And lastly I will say that the sample size on is limited to about 25% of countries in the world, though there are most of the developed ones.
Singapore is misleading, because 82% of the population actually lives in public housing (HDB). I suppose they're counted as "homeownership" because they are leased for 99 years [1], but that's a strong authoritative state with central planning and management of housing. Lease doesn't build that much equity because at you get closer to the term the value of the lease naturally declines. And you're not free to sell or buy to who you want.
