The Romani diaspora refers to the presence and dispersion of Romani people across various parts of the world. Their migration out of the Indian subcontinent occurred in waves, with the first estimated to have taken place in the 6th century. They are believed to have first arrived in Europe in the 9th century, via the Balkans. Gradually, they came to settle across the areas of present-day European Turkey, Greece, Bulgaria, Romania, North Macedonia, Serbia, Kosovo, Moldova, Hungary, Albania, Montenegro, Bosnia and Herzegovina, Croatia, Slovenia and Slovakia. From the Balkans, they migrated throughout Europe and, in the 19th and later centuries, some migrated to the Americas. The Romani population in the United States is estimated at around one million.
Romani people are predominantly found in Europe, particularly in the Balkans, Slovakia and Spain. The total number of Romani people living outside Europe are primarily in the Americas, and are estimated in total at more than two million. Most Romani populations overseas were founded in the 19th century by emigration from Europe. Some countries do not collect data by ethnicity. As of the early 2000s, an estimated 4 to 9 million Romani people lived in Europe and Asia Minor, although some Romani organizations estimate numbers as high as 14 million. There is no official or reliable count of the Roma populations worldwide. Many Roma refuse to register their ethnic identity in official censuses for fear of discrimination. There are also some descendants of intermarriage with local populations who no longer identify exclusively as Romani, or who do not identify as Romani at all.
