Muban number per subdistrict

As of the end of 2007, there were 7,255 subdistrict and 74,944 muban, this means in average each subdistrict contains 10 muban. There are subdistricts which contain no muban at all - if the subdistrict is completely within a city or town (thesaban nakhon and thesaban mueang) the muban loose their meaning and are no longer maintained. But for the other subdistricts the number of muban can vary quite a bit as well.

The highest values I have come across so far are 30 muban in Huai Sak (ห้วยสัก), Mueang district, Chiang Rai, and 29 muban Ban Rai (บ้านไร่), Lat Yao district, Nakhon Sawan. The lowest non-zero number is 2 in Ban Khuan Mut (ตำบลบ้านควนมุด), Chulabhorn district, Nakhon Si Thammarat. However as I still have no complete muban list the above is just a snapshop of my current data, and I also cannot give more statistics yet like the most common number of muban, the standard deviation from the mean value and so on.

Those 30 weren't the highest number: the subdistrict Sap Samo Thot in Phetchabun had 35 muban in 1970, when two subdistricts were carved out of it, as can be read in the corresponding Gazette announcement.
