As a group. Roma are no more mysterious than anyone else is. Roma belong to an exclusive culture like some other ethnic groups which means that their culture is not generally known and understood by outsiders not of the group. The terms nomad and nomadic lifestyle are thrown about by the media without any understanding of the anthropological definitions. Pastoral nomads travel with flocks and herds to find pasture for their animals as the seasons dictate.
Commercial nomads travel to find sources of work, usually on a predetermined annual circuit.
Roma who are nomadic follow the latter type of nomadism, as do non-Roma travelling salesmen, rock groups and professional lecturers. In Canada, the US and Eastern Europe, most Roma are sedentary and live in houses or apartments in villages, towns or cities. Roma are members of the human race. Anthropologically, they are Caucasian and the Romani language belongs to the Indo-Aryan family of languages. Roma are no more secretive about their affairs any other ethnic group.
