East Bay Jewish Community Study - Jewish Federation of the ...

Population Estimates
The following are the population estimates for both households and individual Jews in the East
Bay. These estimates are derived from this demographic study of Jews in the East Bay, as well
as a sample of all adults ages 18 and up in the East Bay. 4
The full dataset of Jews and non-Jews was used in developing these estimates. The data for
respondents’ ages, religion, number of adults in the household, and number of children in the
household were imputed to account for break offs and non-responses, and the overall
population was weighted to match census data for the geographic area on age. The self-report
of being Jewish or part of a Jewish household from the survey interviews was then extrapolated
to allow for an estimate of the numbers of individuals Jews and Jewish households in the East
Bay.
At an individual level, the survey estimates the overall Jewish population in the East Bay to be
176,816, which includes Jewish individuals and non-Jews living in Jewish households.
