Gypsies are one of the most famous though least known national minorities, representatives of which can be found in many countries. Several works have been written about them but no analysis has yet been made of the interrelationship between Gypsies and the nationalities among whom they live. An analysis of this kind is timely in that it would give governments a means with which to alleviate ethnic tensions by amending their present faulty nationality minority policies.The author of this article has recently made a detailed sociological study by means of a lengthy questionnaire of the attitudes of various nationality groups towards each other in Ukraine. Included in it are questions either directly or indirectly relating to the Gypsies. This ethnic group, despite its relatively small size, is well known throughout Ukraine. Gypsies stand out from the rest of the population by their way of life and by their appearance; as a rule, they speak their own language, even though they know the languages of other nationalities. Most of the population of Ukraine comes in contact with Gypsies, though most often with their worst representatives (swindlers, extortionists, etc.). They meet these Gypsies in the most populous places—at railroad stations, outside large stores, and in marketplaces.
