Data File:
The data file from the 2018 Survey of Jews in Canada has been made available by the Principal Investigators: Robert Brym, Keith Neuman and Rhonda Lenton. The Berman Jewish DataBank thanks them for making the data file and related documents accessible and for allowing the DataBank to post and archive:
(a) A Weighting Document which explains how weights were constructed for the combined National sample of 2,235 respondents, as well as for the Toronto, Montreal, Winnipeg and Vancouver surveys separately. Please read the weighting document to understand why there are two sets for weights: the original weights which weighted the National Data and the data for each of the four local communities separately using age and gender post-stratification, and a series of “new” weights which modified the original weight using internal survey data on whether the respondent was married to a Jewish partner.
(b) The 2018 data file via the DataBank is in SPSS SAV format, unweighted as the default: 2,335 cases and 448 variables. The DataBank PUBLIC SAV file has been slightly reorganized by the Berman Jewish DataBank staff to reflect DataBank archival policies and to place all weights near the top of the data file.
For example, the original National Weight (“WEIGHT_NATIONAL) is followed by the “new” national weight (NewWt2_National); the same pattern holds for the original and “new” weights for Toronto, Montreal, Winnipeg and Vancouver.
The original weights reflect age and gender data adjustments to the survey based on comparison of survey and census results; the “new” weights add “inter/out marriage” as a weighting factor to the initial age-gender adjustments.
In the original data file structure, the original weights were located at the top of the survey, while “new” weights were located at the end of the data file, since they were added by the research team after analysis of the data using the original weights. While the separation of the original and “new” weights was not confusing for the original research team, the DataBank staff moved all weights to near the top of the file so that users not at all familiar with the file structure would not assume that the weights near the top of the file were the only possible weights to be used. Again, please read the weighting document before analyzing survey results.
(c) Again, the SPSS SAV data file’s default status is “no weight.”
For purposes of checking the data file’s accuracy after downloading, the unweighted Ns for “QA4_City” are a National total of 2,335, of which 1,135 are from Toronto, 638 are from Montreal, 361 from Winnipeg and 201 from Vancouver.
The weighted Ns using the original National weight are National 2,335 – 1,378 Greater Toronto, 677 Metro Montreal, 93 Metro Winnipeg and 187 Metro Vancouver.
Finally, the “NewWt2_National” weight is reflected in 2,335 total nationally, but with 1,355 Toronto, 671 Montreal, 100 Winnipeg and 210 Vancouver.
Survey results should be analyzed using one of the two National weights or the alternate local community weights, since: (a) the national weights reduce the impact of the unweighted Winnipeg interviews on national findings, and (b) original local community weighting reflected only age and gender, and not intermarriage status which varied considerably by community.

Downloadable Files via the DataBank.
The Berman Jewish DataBank thanks the survey's principal investigators and sponsors for allowing us to post and archive materials from the 2018 study. Downloads include:
Under Reports
(1) The Final Report for the project by Robert Brym, Keith Neuman and Rhonda Lenton (about 90 pages), which includes an Introduction, an Executive Summary, nine chapters summarizing Jewish life in the four cities surveyed, and a methodological appendix.
(2) The Executive Summary of the report's findings (15-17 pages), as later published in the American Jewish Year Book.
Under Slide Decks
(3) One of the slide show summaries of the study results organized by Robert Brym and presented to the Union of Reform Judaism (25 pages approximately).
Under Questionnaires and Frequencies:
(4) The English version of the questionnaire (28 pages) is also available for downloading on this study page.
The questionnaire should be especially useful for researchers who want to compare survey data from the 2018 Survey of Jews in Canada to the results of the Pew 2013 survey of US Jews. The 2018 Canada survey questionnaire has question-by-question references to the 2013 Pew questions that were used in the Canadian survey to make comparisons more valid; the questionnaire also indicates which questions derived from FOCUS Canada surveys and those which were created specifically for the 2018 Canadian survey.
(5) Cross-Tabulations: The authors have provided a series of extensive cross-tabulation analyses in a separate, downloadable document in "banner" style, analyzing most of the key survey questions by many of the key sample demographics (over 500 pages).
Under Documentation
(6) A weighting explanation document prepared by the research team which explains the ten weights available in the data file.
There are five original weights: the combined four-city sample ("National" weights) plus the original weights for analyzing each community's data - Montreal, Toronto, Winnipeg and Vancouver. The original National Weight weights the entire sample by the size of the Jewish population in each city, so a combined analysis is possible, despite differences in sample allocation and completed interviews. The original 4 community weights "weight the sample for each city by the age and gender distribution of Jews in that city" using 2011 National Household Survey results.
There are also five parallel "new" weights which were introduced to modify the original weight by an estimate of intermarriage, using the religion of the respondent's marital or common law partner. Syntax used by the researchers to construct the weight modified by in-marriage-outmarriage parameters is presented in the "weighting document." The resulting variables are always labeled as "new2." Thus, there is a "new2Weight_National," as well as "new2Weight_Montreal," etc., which modifies the original weight Jewish community weight for intermarriage.
As noted in the discussion of the DataBank's reorganization of the study Data File, the original weight for the National data, and for each city, is always followed by the revised, "new2" weight. Obviously, the "new2" weights were constructed after review of data on intermarriage, so they were placed at the end of the original data file - but then moved by the DataBank to the front of the data file.
Under Data Files:
(7) The project Data File in a zipped format which has an SPSS SAV data file with 448 variables and 2,335 respondents. The data file default is "unweighted." Data file users should review the weighting document and decide which weight to use when making different analyses.
The SPSS SAV file has also been saved as a portable SPSS version (POR) which can be used to import the data into other data analysis software programs. Since some variable name labels are truncated in this process, the SPSS SAV version is the preferred data file.
Under Other: several articles based on the survey's data by the researchers.
(8) Article on Jewish Religious Intermarriage in Canada (Brym, Lenton).
(9) Article on Antisemitism, Israelism and Canada (Brym, Lenton).
(10) Article on Qualifying the Leading Theory of Diaspora Jews: an examination of Jews from the former Soviet Union in Canada and the United States (Brym, Slavina, Lenton).
