Okay, I've been seeing defence.pk a lot on search results for over a year now, and I've read many threads before, and despite the fact that there were many discrepancies and misinterpretations and what not, this kinda does it. I just had to make an account to show that most people here never bother doing any of their own research.
Pew used a set of 13 questions to determine the SHI-
(Refer Appendix-E from the report)
Here are the ones where India and Pakistan differed followed by the reason listed by Pew-
Were there detentions or abductions motivated by religious hatred or bias? (no abductions in India)
Were there acts of sectarian or communal violence between religious groups? (no violence between groups in Pakistan)
Was there a religion-related war or armed conflict in the country (including ongoing displacements from previous wars)? (more deaths in Pakistan)
Did violence result from tensions between religious groups? (more cases of physical violence in India)
Were there incidents of hostility over proselytizing? (no cases in Pakistan)
Now, India has a religious diversity index score of 4.0, whereas Pakistan scores 0.8
(Look up the religious Diversity Index Table by Pew Research Center, I'm not yet allowed to post links here, which is why I haven't)
This means that there is a greater scope for communal violence between groups in India than in Pakistan, which is why India failed the 2nd and the 5th question
(NOTE- Lack of communal violence between groups in Pakistan does not indicate safety, it indicates the one-sided nature of violence)
And given the fact that India has more than 1.3 billion people, the number of cases involving physical violence among religions will obviously be greater in India than Pakistan, hence the 3rd question.
Also, this is from Pew Research Center too, not sure how many of you even bothered reading it-
"This is not to suggest that all members of these religious populations were harassed because they lived in countries where incidents may have occurred. Indeed, there are often important regional differences in harassment, especially in large countries such as India, and most people living in these countries probably did not experience harassment directly. But this analysis does demonstrate how geographic distribution – or lack thereof – may intensify the impact of harassment for certain groups."
