I'm always a bit sceptical of PolyMatter's videos indeed, thank you for pointing that out. However, your link suggests a ratio of 17:1 with Chang Mai in the list, which is still quite high and also on the same page there is the contradictory mention of a 35:1 ratio with Nakhon Ratchasima (in the 'Examples' section). The Wikipedia 'Bangkok' page says the population (metro) is 14M, while this Wikipedia page says 17M. Other sources have wildly different numbers too. 5M here for example, suggesting a ratio of 13:1 with Samut Prakan, yet another city: https://www.worldometers.info/world-population/thailand-population/ https://www.worldometers.info/world-population/thailand-popu... ("includes boroughs, districts, urban agglomerations, etc.")
