Questions this page answers
What does the distance mean?
Percentile points. It is the root-mean-square gap between two cities across the metrics both have, so 6 apart is closer than 14 apart. It is not a score out of 100 and it is not a percentage.
Which pair is the closest?
Kaohsiung City and Tainan City, 3.8 percentile points apart.
Does similar mean better?
No. Two cities can measure alike because both score badly on the same things. The table says how alike they measure, never which to pick.
Why do only some cities have a page?
A city needs at least 5 matches above the similarity floor and enough shared metrics to compare on. 45 cities clear it; the widest cluster is Kuala Lumpur at 15.8 apart.
