Ukrainians make up almost 77.8% of the total population, while Russians take the second spot with almost 17% of the population. Other minorities include Bella Russians 0.6%, Bulgarians 0.4%, Hungarians 0.3%, Crimean Tatars 0.5%, while Romanians and Poles both are 0.3% and Jewish residents make up 0.2% of the total population. Other minorities present are 1.8%.
Based on that, and the country's population of 41 million, you've got a couple thousand, maybe 10,000, blacks across the whole country.
