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 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 that there were mistakes besides the census the sources i used were and as well as this site for the actual map
