The majority of them were born in Pakistan within the last four decades and mostly belong to the Pashtun ethnic group. They also include Tajiks, Uzbeks and others. Major ethnic groups Punjabis Punjabis are an Indo-Aryan ethnolinguistic group associated with the Punjab region in South Asia. They are the largest ethnic group of Pakistan. Traditionally, Punjabi identity is primarily linguistic, geographical and cultural. Its identity is independent of historical origin or religion and refers to those who reside in the Punjab region or associate with its population and those who consider the Punjabi language their mother tongue. Integration and assimilation are important parts of Punjabi culture, since Punjabi identity is not based solely on tribal connections. Pashtuns Pashtuns are an Iranian ethnolinguistic group and are Pakistan's second largest ethnicity. They speak Pashto as their first language and are divided into multiple tribes such as Afridi, Yousafzai and Khattak, which are notably the main Pashtun tribes in Pakistan. They make up an estimated 38 million of Pakistan's total population and are mostly adherent to Sunni Islam. Notable Pashtuns include former president Ayub Khan, former prime minister Imran Khan, cricketers Shahid Afridi and Shaheen Afridi, actor Fawad Khan and Nobel Laureate Malala Yousafzai. Sindhis The Sindhis are an Indo-Aryan ethnolinguistic group who speak the Sindhi language and are native to the Sindh province of Pakistan. Sindhis are predominantly Muslim, but have a minority Hindu population, making up the largest Hindu minority population in Pakistan. Sindhi Muslim culture is highly influenced by Sufi doctrines and principles and some of the popular cultural icons of Sindh are Shah Abdul Latif Bhitai, Lal Shahbaz Qalandar, Jhulelal and Sachal Sarmast. Saraikis The Saraikis are an Indo-Aryan ethnolinguistic group inhabiting parts of central and southeastern Pakistan, primarily in the southern part of the Pakistani province of Punjab. They are mainly found in Derajat, a cultural region of central Pakistan, located in the region where the provinces of Punjab, Khyber Pakhtunkhwa, and Balochistan meet.
