About the Bugeac image Ok sorry to answer so late The map was originally created by Anonimu and he based his map exclusively on the Soviet census of 1989 if I am correct He did not post it on the article he just suggested it as a possible map however everyone sort of ignored it I contacted him and inquired about it I took the map and changed it in areas where i knew for sure from census data from 2001 that there were mistakes Besides the census the sources I used were and as well as this site for the actual map
