How to get data of settlements of a certain settlement?

Question

Google Maps

It is necessary to somehow find out / get a list of settlements in a certain area. For example, there is a folk map yasha . The region (Mytishchi district) is highlighted on it. You need to get a list of the settlements included in it (villages, towns, villages, cities, etc.). The data on the map may not be relevant, i.e. something may be missing. I compared many maps and data from Wikipedia - this particular folk map most fully displays data on settlements, but again, not completely, something is missing.
Maybe someone knows where you can find complete data on the composition of certain areas?

Answer 1

Alternatively maps.rosreestr.ru/portalOnline

Answer 2

Perhaps the classifier of territories of municipalities (OKTMO) is suitable:
mydata.biz/ru/catalog/databases/oktmo

Answer 3

OpenStreetMap data - Mytishchi district . Found 75 out of 94 by OKTMO.
