Administrative units & cities messed up in Poland, Bhutan, the United Kingdom #1019
Description
We've been trying to use your API to make a list of states/ provinces/ regions in various countries.
We have tried so far about 10 countries and we found issues in the following ones:
The United Kingdom
Bhutan
Poland
In the United Kingdom, Bhutan and Poland, various levels of the administrative regions are messed up. As the problem appears in many results, I suppose it is a broader issue than just a few countries. More about it below.
For example:
POLAND
In Poland, the divisions are roughly as follows: Voivodeships > Powiats > Gminas > Cities
There are some intricacies to that, but by no means is a powiat a city. More here: https://en.wikipedia.org/wiki/Administrative_divisions_of_Poland
The request
https://api.countrystatecity.in/v1/countries/PL/states/[siso]/cities
returns both cities & Powiats together. This is wrong because a city is a smaller unit that is a part of a powiat, not an equal unit.
Therefore, the API should return only cities within a voivodeship.
UNITED KINGDOM
The United Kingdom is divided into countries (England, Northern Ireland, Scotland, Wales) and they are divided into smaller units - counties - see the information under "Local government" in Wikipedia: https://en.wikipedia.org/wiki/Counties_of_England that lists all (metropolitan and non-metropolitan) counties.
Your API
https://api.countrystatecity.in/v1/countries/GB/states
returns 247 units of which some are countries (eg. England), some counties (that are part of countries), some cities (eg. Darlington, Doncaster, Glasgow etc. that are part of counties) and some even local councils (which are yet another type of unit).
Also, the result is missing many counties, such as West Yorkshire, South Yorkshire, Durham.
There is no logic in it whatsoever.
You either need to return countries in the above API or return counties. By no means, various administrative levels should be mixed, nor should cities be put in the states result.
BHUTAN
https://api.countrystatecity.in/v1/countries/BT/states
returns 19 districts while there are 20 districts in Bhutan (Trashiyangtse District is missing).
The following:
https://api.countrystatecity.in/v1/countries/BT/states/22/cities
returns Wangdue Phodrang city as part of the Dagana District, while it is part of Wangdue Phodrang District (by the same name as the city). There are other mistakes like this in the Bhutan cities result.
