The domain investor has noticed that the height of people in a region depends to a large extent on historical factors. Since goa was ruled by the Portuguese for about 500 years, and a large number of Europeans came to goa, most goans are taller compared to other indian citizens since they may be having Europeans genes and are taller. Tall people often openly ridicule shorter people, who they feel are inferior.
Similarly north india was invaded repeatedly by Alexander the great from greece, persians, mughals and others from north asia, europe who are taller than native indians. So north indians, especially from haryana,punjab are likely to be taller and fair skinned compared to other indians
