That is what the Indians will tell you. That is what few in Pakistan will tell you.
Are they differant? Yes and No. Of course it';s not like on this side they have one eye and three legs and on other they have two eyes and four legs. Think of Chinese/Vietnam border. Think of Chinese/Indian border in Ladakh. On both sides you have Buddhist Tibetan peoples but that does not mean China and India are same?
Pakistan and India share
one province called Punjab which is on both sides of the border. This has a line cutting through it based on religion. On both sides you have ethnic Punjabis differantiated by religion. Punjabi Muslim on Pakistan side and mostly Punjabi Sikh on Indian side. However only
2.5% of India is Punjabi. The other 97.5% is other ethnic groups which get
more divergent from Pakistan further east/south you move into India from the border.
Punjabi Muslim - Make about
50% of Pakistan
Punjabi Sikh - Make about
2.5% of India.
The two Punjabs that were divided in 1947. Lahore is capital of Pakistani Punjab province. Amritsar is Sikh holy city in Indian Punjab with border inbetween.
The Punjab in Pakistan dominates the country at 50% of the population as one province with four province federation. The Indian Punjab is
tiny part of India at just about 2.5% of the population. The map below contextualizes Indian Punjab [
red] as
one state within rest of the
29 Indian states union.
Hoewever don't let 2.5% hide the reality. Indian Punjabi Sikhs make big chunk of Indian Army and play a role in India far, far greater than their number suggests. So the Indian Punjabi Sikhs make a bigger part of the Indian ethnic mosaic at least at the public/popular perception then their numbers would suggest. I suppose a crude analogy might be Jews in America who despite being a tiny minority make big impact on the public scene.
Here below is
Indian Punjab within other 29 Indian states.
I hope this answers your question. Just as a sidenote if you look at the Pakistan ethnic group map [first top] you will notice the Baloch carry over into Iran. The Pakhtuns carry over into Afghanistan. The Punjabi Muslims carry over into India as Punjabi Sikhs. Only Sindhis are restricted within Pakistan.
