its highest frequency in South Asia where it ranks first as the largest share of the earth 's population. In Southeast Asia the share of the population is high, especially in Thailand and Indonesia, then in East Asia, Northern Asia and neighboring Central Asia, and its incidence diminishes both towards the east and the west, falling to single digit percentages in Netherlands, Norway, Portugal and Switzerland. It is believed to have been entirely absent from Native American and Australian Aboriginal populations prior to the arrival of Europeans in those areas. Blood group A is associated with high frequencies in Europe, especially in Scandinavia and Central Europe, although its highest frequencies occur in some Australian Aboriginal populations and the Blackfoot Indians of Montana, the US.
