In general, the Jewish population skews older. With a relatively low birthrate and declining religiosity among younger Jews, the national Jewish population tends to be older than the general population. However, the unweighted age distribution in this survey appeared too old even when considering this fact. Figure 97: National Census Age, National Jewish Age National Age (2010 US Census Data) National Jewish Age (2000 Jewish Population Survey) 20-29 19% 18% 30-39 18% 15% 40-49 20% 19% 50-59 18% 18% 60 and over 25% 29% Ultimately we decided that it was necessary to weight the age distribution slightly to obtain the most accurate population estimates and analysis possible. Weight targets were obtained after weighting the total dataset (including Jewish and non-Jewish households) to Census data. Using the Jewish households portion of this weighted data set, we were able to obtain targets and weight the data. 106

Because there is a correlation between the chance of someone breaking off and their demographic characteristics, those who break off in the middle of the survey have distinct characteristics. This will, in turn will have biasing effect on the Jewish incidence estimation. In order to minimize and correct for potential biases from break offs and invalid responses such as don’t know or no answer, we imputed missing values with statistical algorithm called multiple imputation. The literature in missing data suggests we create at least five imputed datasets and obtain estimates by averaging estimates across imputed datasets. We created 10 imputed datasets and then adjusted the margins of error as suggested by Little and Rubin (1987). 29 27 ―Jewish Community Study of San Francisco‖ 2003.
