These are always so unreliable because they never adequately account for the wide range of housing costs you can get in different cities when you take into account public transit as well as family size and whether you'll be willing to have roommates.

You basically need to sub-divide and rank these across commute times + family/roommates preferences. So Top 10 most expensive within 10 minute commute, within 20 minute commute, within 30 min commute, etc., further broken by family/room requirements.

For example, if you want to live in Manhattan then sure you can pay 1500 for a bedroom.

But a better bedroom that's still within 30 minutes commute of a Manhattan job for a $3 subway ride is $900. Just have to choose based off what part of the city your job will be in and live with 2-3 of your friends.

This, there is no possible way, when the housing cost of similar space and furnishing are included, that Hong Kong would be equal to Singapore and Paris.

Most of the figure tends to use 1 bedroom or 2 bedroom as calculation. You will then have to look at the bedroom in HK are very likely smaller than some of your kitchen in Paris.

And then it is further lowered by having the one of the cheapest McDonald in the world.

Yes, LOL, my family of 13 is always off the charts.

Another problem is that lots of people don't live in cities. Covering only the big cities is an easy way out, but completely useless for many people. Since the non-city areas are numerous but don't have well-known names, you really need a map.
