People who have left their home country, usually involuntarily to foreign countries around the world can be defined as diaspora. The word ‘diaspora’ comes from the greek work ‘diaspeirein’ that means dispersion. The start of diaspora can be traced back to the migrations of Jewish people after the fall of Jerusalem in the sixth century B.C.E. in today’s world; it has been saifd that India has the biggest diaspora by a huge margin. Studies show that that Indian diaspora developed gradually during the 19th and 20th century. There are also advantages and disadvantages of diaspora. One of the biggest problem and disadvantage is the cause of discrimination under racial grounds, the disparity in jobs and racial abuse due to terrorist branding; there can be cultural integration and lots more. The advantage is that it can play a vital role in one’s the economic development of their countries of origin. It can also promote trade and foreign direct investment, create businesses and spur entrepreneurship, and transfer new knowledge and skills. Diaspora has ultimately helping to boost job creation, living standards, and higher growth.
