The Pew Research Center released a survey of American Jews Tuesday. A Portrait of Jewish Americans survyed 3,475 Jews, including 689 who identify as having no religion, between February and June.
One in five Jews describe themselves as having no religion.
Those born after 1980 are the most likely to say this.
The average household size for Orthodox Jews is higher than any other denomination.
48% of those raised Orthodox are currently Orthodox and "they are much younger, on average, and tend to have much larger families than the overall Jewish population [which] suggests that their share of the Jewish population will grow," Pew reports.
