Re: Pakistan Punjab vs Indian Punjab
Interesting discussion
I think I understand where you are coming from though since most Pakistani Punjabis live in Punjab (vs other parts of Pakistan) so there is some homogeneity there. However, cant really apply that to to Indian Punjabis since the Pakistani side is bigger than the Indian side, and most people who moved from the Pakistani side to India during partition ended up settling in various parts of India (not Punjab). Also, there has been a lot of migration driven by jobs etc which has spread people geographically.
There are many Punjabi families living in Mumbai for example who would fit the rest of the criteria you have mentioned. Bollywood is full of such people.
