People of Pakistan
The population of Pakistan comprises several main ethnic groups - Balochis (3.57% of the population), Muhajirs - refugees from India (7.57%), Punjabis (44.15%), Pashtuns (15.42%), Seraikis (10.53%), Sindhis (14.1%), and others (4.66%). Smaller ethnic groups are mainly found in the northern parts of the country such as Turwalis, Kafiristanis, Hindko, Brahui, Kashmiris, Khowar, Shina etc. Pakistan's census does not include the sizeable refugee population from neighbouring Afghanistan, who are found mainly in the NWFP and Baluchistan. From the 1980s, Pakistan accommodated over three million Afghan refugees - the largest refugee population in the world, including Pashtuns, Tajiks, and Hazaras. If Afghan refugees were added to the official population, total figures would alter the percentages of Pashtuns and the category of others. A large number of Bengali immigrants are concentrated in Karachi, while hundreds of thousands of immigrants from Iran are scattered throughout the country.
