'...Commonly referred to as "Gypsies", the Romani, ethnically and genealogically disparate from other Europeans, began settling in America in the mid 19th century, fleeing centuries of persecution in Europe. Americans were and are largely unaware of the cultural and historical prejudices about Romani held by Europeans, and though American Romani are cautious about the stigma associated with their heritage,[2] they do not face discrimination or bigotry as they do in Europe. As a result, the social and economic position of Romani in the United States is substantively more favorable than in Europe, with many running successful family-owned businesses, and blending seamlessly into the community.[1]
The largest wave of Romani immigrants came after the abolition of Romani slavery in Romania in 1864. Romani immigration to the United States has continued at a steady rate ever since, though a large-scale surge of Romani immigration followed the 1989 collapse of Communism in Central and Eastern Europe.[1]
Due both to the size of the American Romani population and the absence of a historical and cultural presence, such as the Romani have in Europe, Americans are largely unaware of the existence of the Romani as a people, associating the term "gypsies" with a trade or profession more than a cultural and ethnic heritage.[1] Due to the term's lack of significance within the United States, many Romani do not use the term around non-Romani: identifying themselves by nationality rather than heritage. The U.S. Census does not distinguish Romani as a group, since it is neither a nationality nor a religion.[1]..'
