CMJS Combined Dataset
The Combined Dataset (CDS) combines data from 25 socio-demographic studies of federated Jewish communities, conducted between 2015-2023 by the Cohen Center for Modern Jewish Studies (CMJS) at Brandeis University. This CDS includes survey responses from more than 53,000 respondents including information about demographics and household composition; Jewish identity, behaviors, and attitudes; and financial and social service needs.
It is important to note that the CDS is not drawn from a random sample of communities, but from the ones that conducted a community study with CMJS in the past 10 years. Consequently, the population described by this dataset does not represent the entire US Jewish community, but only the Jewish population in these communities. Nonetheless, the characteristics of the combined dataset align closely with estimates of the US Jewish population as a whole. The study includes small, medium, and large communities from all US regions.
