TECHNICAL APPENDICES © 2020 Brandeis University. Revised June 2020. Maurice and Marilyn Cohen Center for Modern Jewish Studies www.brandeis.edu/cmjs The Cohen Center for Modern Jewish Studies (CMJS), founded in 1980, is dedicated to providing independent, high-quality research on issues related to contemporary Jewish life. The Cohen Center is also the home of the Steinhardt Social Research Institute (SSRI). Established in 2005, SSRI uses innovative research methods to collect and analyze socio- demographic data on the Jewish community.

As survey techniques have become more refined, the barriers to reaching respondents have become increasingly difficult to overcome. Researchers typically experience limitations in reaching respondents due to the proliferation of survey research, the prevalence of cell phones, and caller ID/blocking. Low-incidence populations are particularly hard to reach using the traditional method of random digit dialing (RDD) because the likelihood of reaching someone in the target population depends upon the size of that group relative to the population as a whole. To address these barriers, CMJS has utilized a research design that incorporates two innovations: Data from an extended sample of email-only respondents Use of organizational data to correct for sampling bias The research design for the Howard County Jewish Community Study utilizes random sampling from an identified frame, or list, of the known population. Local Jewish organizations provided their own lists. These lists were combined with a purchased list of likely Jewish households within the geographic area and were then deduplicated. The combined list constituted the sampling frame from which a primary random sample of households was drawn. Because this primary sample was a random selection from the overall frame, it is assumed to be representative of the entire frame. For that reason, data collected from the random sample were used to estimate overall population characteristics. To supplement the primary random sample, a second sample was drawn from a frame consisting of the remaining households who had an email address. Information from these households increased the amount of data available from populations of interest and allowed for more detailed analysis of the characteristics of the community. 1. Sampling Frame The 2019 Howard County Jewish Community Study implemented a dual-mode internet and telephone survey to reach year-round and seasonal residents of the Howard County area. In the absence of an area probability or RDD frame, we built a sampling frame from the combined mailing lists of Jewish organizations in Howard County and Baltimore. The numbers and types of organizations included in the lists are shown in Table A1. 2 Table A1.
