Abstract
Abstract In response to Isaac Sasson and Sergio DellaPergola’s commentaries on our assessment of the validity of the Pew Research Center's 2020 estimate of 7.5 million US Jewish adults and children (Tighe et al. 2022), we address key points of agreement and contention in the validity of the estimate; in particular, how the Jewish population is identified and defined. We argue that Pew’s definition of the Jewish population is consistent with major studies of American Jewry, from NJPS 1990 to recent local Jewish community studies. Applying a consistent definition that includes the growing group of “Jews of no religion” with one Jewish parent, as Pew Research Center does, allows for a faithful comparison across national and local studies and a more accurate understanding of levels of Jewish engagement and expressions of Jewish identity.
