Question: Why do some Mexican states have second- or third-level subdivisions, but the rest have fourth-level subdivisions?
Municipalities are the standard second level subdivision of Mexico. However some states merge them into larger areas while others do not.
 
While working on my historical map I realized that the border between Alberta and British Columbia should match with the western border of Glacier County in Montana, I would try to fix this myself, but I don't know exactly where is the problem: Canada, the US counties or both

The placement of the reservation is the problem. Where the Continental Divide is, is where Glacier National Park is.

I don't know the relation between Reservations and National Parks, but could national parks exist within Indian Reservations

I have been revising the whole border, and I found the same problem with counties in Minnesota, however there, the difference is not that remarkable (just one pixel at first) but the further west you go, the greater the difference...

I realized that Canada borders correspond to older versions of the Qbam map, is it possible then, that the borders in Canada should be patched?

Is the data in Bosnia, Serbia, and Montenegro so insufficient that we only have the national population density?
The lack of precision is from the base map. It could be modified, there are some more accurate maps of Serbia, Montenegro and Bosnia. Also the Sahara desert and Saudi Arabia I think they should have less population density
 
So I got tired of georeferencing maps and then overlaying them on QBAM and finding that the Nile seems to be off despite the georeference being perfect. So I edited it.

Behold! I have mapped all of India's divisions. Version without rainbow colors:

Also, some of India's districts need redoing, as new districts have been created. I've done Bihar, but some others (Chhattisgarh I'm looking at you in particular) need redoing.

You missed two three states there: Tamil Nadu, Andhra Pradesh, and Gujarat.

Also, we're going to have a field day with Telangana. The state has 33 districts since 2019.
