The survey in India is part of the larger Spring 2012 Pew Global Attitudes survey conducted in 21 countries under the direction of Princeton Survey Research Associates International.
Results for the survey in India are based on 4,018 face-to-face interviews of adults conducted March 19 to April 19, 2012. It uses a multi-stage cluster sample in 13 of the 15 most populous states (Kerala and Assam were excluded), plus the Union Territory of Delhi, representing roughly 86% of the adult population. The sample is disproportionally urban, but the data are weighted to reflect the actual urban/rural distribution in India. Interviews were conducted in Hindi, Bengali, Tamil, Kannad, Telugu, Gujarati, Marathi, and Oriya.
The margin of sampling error is ±3.9 percentage points. For the results based on the full sample, one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus the margin of error. In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
