Jewish Federation of the Quad Cities, Illinois/Iowa

The report, "Toward the Year 2000: Quad Cities Jewish Life," was published in January, 1990.
The report estimated the Jewish population of the Quad Cities to be 1,350, a downward revision of the American Jewish Yearbook 1988 estimate of 1,650.
The "Quad Cities" are on the banks of the Mississippi River, in both Iowa and Illinois. The region is made up of Davenport and Bettendorf in Iowa and Moline/East Moline and Rock Island in Illinois, and surrounding communities.
74% of households which received the questionnaire responded; 435 returned questionnaires.
The response rate of unaffiliated Jews was virtually identical to that of synagogue members. Thus, the investigators concluded that the data obtained are representative of the Jewish population of the Quad Cities.
In order to obtain a proportional representation of males and females, the investigators identified a person in each household who was to complete the questionnaire. However, with mail questionnaires, confirmation is not possible.
