What parts of the Soviet Union had a large percent of their Jewish population murdered by 1943?

By 1943, significant parts of the Soviet Union, particularly the territories in Western Ukraine, Belarus, and the Baltic States (including Lithuania, Latvia, and Estonia), experienced devastating losses of their Jewish populations due to the Nazi invasion and subsequent mass shootings. In these areas, Jewish communities faced systematic extermination, with many being murdered by Einsatzgruppen (mobile killing units) and local collaborators. The urban centers in these regions saw particularly high percentages of their Jewish populations killed, often exceeding 90%.
