A diaspora is a large group of people with a similar heritage or homeland who have since moved from their original homelands to another country. In terms of ethnicity, they share a common language, worldviews, myths, religious concepts and rituals, social customs, and food. The Greek term dia speiro ("to sow over" or "to scatter about") indicates a transplanting of a culture from one area to another.
