"Mirpuris" are a minority. They are only a huge population in Britain because of this: http://en.wikipedia.org/wiki/Mangla_Dam In Pakistan, Punjabis and Pashtun are the largest ethnic groups. 1. Punjabis (42%) 2. Pashtun (17%) 3. Sindhis (14%) 4. Seraikis (10%) 5. Muhajirs (7.5%) 6. Baloch (3.5%) 7. Other (4.6%) Mirpuri, Potohari/Pahari, Hindko, etc are not Punjabi and are not Pashtun. They are from the "Other" in the above list. They are academically classified as speaking "Western Punjabi" languages but a Punjabi speaker (such as from Lahore or Faisalabad or Indian Punjab) cannot understand them and vice-versa. They can all understand each other's languages. Culture-wise they share some aspects with Punjabis and Kashmiris. Mostly with Kashmirs (however Kashmiris are a different group though they live nearby). They tend to mostly be Barelwi, conservative, fitting the stereotype of the Pakistanis you just mentioned. Almost all Pashtun are Deobandi. A large number of Punjabis are either Deobandi (especially from Central or South Punjab) or Barelwi but towards the East, so having not too much in common with "Pahari" culture. They seem to share culture with the Indian Punjabis (Sikhs) more than they do with the Mirpuri/Pahari people. They are very anti-Deobandi and anti-Taliban. Please do not confuse British Pakistanis with Pakistanis in Pakistan or even Pakistanis in the United States (most of whom seem to be Punjabi). They are not reflective of any other Pakistani demographic in the world except for these few cities in the border between NWFP/Punjab/AzadKashmir. The most popular religious movements in Bangladesh (Deobandi movements and Jamaat-e-Islami) came from Pakistan (well Deoband technically started in India in 19th century). Besides, this is a silly point to bring up. Do you really want to compare religiosity in the Western Pakistani and Bengali communities?
