Eleassar I don t know whether Doremo and me are more knowledgeable than you Doremo maybe is a native English speaker but that didn t help to find sources that you and me found I am just comparing what is done in some places in Wikipedia and what has been done here Reading and comparing is all I did Also checking against native English sources You said the opposite change has been going on for years the first Municipality of that I found via the template is from June 2012 That is more than three years after Yerpo established X municipality in commons and even more years after text usage of X Municipality in articles Doremo the usage of the word municipality as a class name in toponyms is marginal for native English countries In Allegheny County PA the municipalities are named X Township X Borough i e Google tests may find municipality of X there but in fact it will be municipality of X Township or so And the article in Wikipedia is at Aleppo Township Allegheny County Pennsylvania For the entities from Eastern or Northern Europe having class names like kommun or opstina and being locally called opstina X X kommun the situation is different There is the base name X and then a class name is applied to the full set That makes the situation similar to 10 native English country South Africa and the local municipalities in that country A local website can be found at having X Municipality in large letters at the top or at having Overstrand Municipality in the text of the home page So I think for South Africans it would not be perceived as marginal to say X Municipality
