I would like to, firstly, report that, I think there are a number of mistakes in the administrative level data. Or, at least, it is not clear to me why there should be differences in some definitions between countries.

If I obtain a list of administrative divisions for Angola,

EntityValue[ Entity["AdministrativeDivision", {EntityProperty[ "AdministrativeDivision", "ParentRegion"] -> Entity["Country", "Angola"]}], "Entities"]

The list of results that follows from this command (see below) matches 18 Angola's official division level 1 districts (see here).

Whereas for Burkina Faso, this is not the case, and the same command seems to return the 45 admin level 2 entities (see below), rather than the 13 admin level 1 districts (see here).

I have also noticed issues with other aspects of the admin data, for example, Swaziland has the incorrect number of districts by this measure, with one of them actually being in South Africa.

Does anyone know how I can get the entities I want -- a list of true admin level 1 districts for countries in Africa? I notice that there is an EntityClass object,

EntityClass["AdministrativeDivision", "ADM1"]

But, to tell you the truth, I haven't a clue how to use this to get countries in Africa. Nor am I confident that the data which come from these attempts will be correct. If anyone does have an idea how to do this, though, please let me know. Best, Ben

    $\begingroup$ Yeah, would be great if somebody would curate the "curated data". I think you should send hints to errors in curated data directly to Wolfram support. $\endgroup$ – Henrik Schumacher Nov 8 '17 at 14:13
