|2007 electoral regions|
Since I already programmed the algorithm for calculating the number of constituencies per province, it's easy for me to compare the two proposed numbers. The only thing I had to program for an easier comparison was to sum up the numbers for regions. To keep the table short I have only used the simple regions as defined by the National Statistics Office, with the northern region already starting at Nakhon Sawan.
The weight of each vote depends on the province, due to the fact that constituencies have to be within one province there's inevitably quite some inequality - whereas in Ang Thong there are 142403 citizen per MP, in Nakhon Nayok the number is 251683 (calculated for 375 constituency MPs). With 400 constituency MPs, Nakhon Nayok would instead be nearly at the top of the list with 125841 citizen per MP, as it is one of the provinces which loose a constituency in the reduction of numbers.
While all reports focus on the numbers only, none mentions whether the electoral regions will be kept or dropped with the amendments. The new value of 125 could only be divided into 5 regions, so there has to be a change in these regions for sure. The lack of mentioning them in the news makes me think they will be dropped altogether. But guess I will only know for sure after the amendments are accepted in a joint meeting of house of representatives and senate on February 11th.
