I would pay attention to the sample size, which IMHO is statistically insignificant.

A couple of observations, Kumar. And a hello to you before I do.

Pew is quite good at surveys. So, since they were willing to report the results on a country by country basis, I would go with it. Unless you know something quite specific is wrong.

Second, as I read the text there were over 3300 successful interviews in Pakistan and India. That should be enough. Again, unless you know something more specific about problems in either country that would require larger samples.

Kumar, I'm curious as to why you think that the sample size is statistically insignificant. The article states that 3306 people were questioned in India and Pakistan. We don't know the breakdown between countries but a 50:50 split would imply a 2.5% margin of error in each country. A sample size of 1200 is still less than 3% M of E.

17,000 respondents in 15 countries gives an average country sample of 1133 which keeps the margin of error in the 3% range. Of course, if some countries had much smaller samples the M of E would be somewhat higher.
