The Centre for the Study of Developing Societies’ Lokniti program runs the incredibly valuable National Election Studies surveys. I’ve been going through them as part of a nascent project on public opinion toward security issues. I thought I’d collect here some NES responses from both nation-wide and J&K-specific surveys. They are not restricted to the Kashmir Valley and cover the entire erstwhile state: this may account for highly polarized pattern of responses to some questions in the 2019 J&K-specific postpoll, for instance (for a deeper analysis with fine-grained data I don’t currently have access to, see this important article in the Hindu).
There are obviously numerous really crucial caveats about how interpret survey responses, especially on politically sensitive topics (for instance, Q9 in the 2014 State Assembly postpoll sees almost 50% refuse to answer a question about the “best solution”). I make no major claims about them and advise enormous caution in offering inferences or policy conclusions, but haven’t seen them collected like this before. So, purely FYI:
2019 NES postpoll in Jammu and Kashmir (questions beginning with JKQ):
The 2014 State Assembly Election Postpoll has so many interesting questions I just suggest you check it out (with huge caveats about survey non-response and biases – there are some wildly high non-response rates in some questions). Methods notes for all of these surveys are available on the CSDS NES or State Election Studies pages.
