Halbjude
Jewish identity began to gain the attention of Jewish sociologists in the United States with the publication of Marshall Sklare's "Lakeville studies". Among other topics explored in the studies was Sklare's notion of a "good Jew". The "good Jew" was essentially an idealized form of Jewish identity as expressed by the Lakeville respondents. Today, sociological measurements of Jewish identity have become the concern of the Jewish Federations who have sponsored numerous community studies across the U.S.; policy decisions (in areas such as funding, programming, etc.) have been shaped in part due to studies on Jewish identity.
