Only Saraiki was present in the last batch of Census data (1998, I think). I don't know whether Potwari-Pahari and Hindko were counted under "other" or under "Punjabi". Here's the data:http://www.census.gov.pk/MotherTongue.htm
Yeah, it's great that there's this diversity, which is why it's such a damn shame Pakistan is doing so little to cultivate it. Only very recently has Khyber-Pakhtunkhwa go mother tongue education (or it was going to, I remember reading it in the paper last time I was in Pakistan and then seeing it again on the internet). There are also Balochi and Sindhi medium schools, AFAIK. Beyond that, there isn't much official recognition for any of the languages of Pakistan (only Sindhi is even explicitly defined as a "provincial language"). Thankfully most of the languages have some sort of regional movement attached to them, the only exceptions being Punjabi (whose regional movement is exceptionally weak, especially compared to the Sindhi or Balochi ones) and Potwari (which may have one but I've never heard of it, the closest I've heard is some British Potwaris insisting on being "Kashmiris who speak Pahari" and not "Pakistanis"
There's this idea in Pakistan that Pakistaniyat
has to be a deductive national identity. What I mean is, that not only do you add Pakistani
to the list of things you are, but you have to substract Brahui
as well. I remember asking some of the security guards on my street what their ethnicity was. Some of them enjoyed it - one man said that he was from NWFP, and was extremely happy when I knew what Pashto was. But some of them are like "no! we are Muslims and Pakistanis first! nothing else matters!". And I think to myself, well no, fuck that! You should be human
Somehow I can't imagine that happening in India. I have this feeling that Indianness belongs to "whoever is in India", while "Pakistani" is taken as synonymous with "Urdu-speaking Muslim". Of course India has the same problems as Pakistan (Bodoland, Kashmir, Tripura...), but not nearly as pronounced.
Anyway, that's my little rant on Pakistani nationalism.
