About This Report

Margins of ErrorPew Research Center completed interviews with 3,475 Jewish respondents, including 517 Orthodox Jews, 659 Conservative Jews, 1,168 Reform Jews and 908 Jews of no denomination. Interviews were conducted by telephone (landlines and cellphones) between Feb. 20 and June 13, 2013, by the research firm Abt SRBI, in English and Russian. After taking into account the complex sample design, the margin of error on the 3,475 completed interviews with the NET Jewish population is +/-3.0 percentage points at the 95% level of confidence. The table at right shows the unweighted sample sizes and the error attributable to sampling that would be expected at the 95% level of confidence for different groups in the survey. More information about the survey’s methodology can be found in the initial survey report’s appendix on methodology.

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.
