Zev Eleff responds to Elli Fischer and Matt Williams' critiques of his essay "The Vanishing Non-Observant Orthodox Jew," clarifying that his study does not delve into patterns of religious observance within Orthodox Judaism but focuses on the social-religious label of the Non-Observant Orthodox Jew, a term that emerged in the 1950s due to economic and social factors.

Zev Eleff's article responds to the notion of a disappearing non-observant Orthodox Jew within the American Jewish community, pointing out the lack of clear definitions and data to support such a claim.

The term "Non-Observant Orthodox Jew" gained attention in the 1970s, describing Orthodox Jews who did not strictly adhere to Jewish law but identified with Orthodox Judaism socially and culturally.
