> This annual report assesses housing affordability in 95 major markets across eight nations (Australia, Canada, China, Ireland, New Zealand, Singapore, United Kingdom and the, United States).

This is hardly a study across the entire world. The US has more than half of these "major markets", the UK has a quarter, and by "China" they only mean Hong Kong.

Ten is really 12 cities, and 8 are in the US. Embarrassing headline.

Odd they'd bundle the tied cities together as 1 list entry in England, but break out the US cities that tied into 2 entries on the list.
