This should worry us. A major Jewish sociologist reports that “non-Orthodox Jewish trend lines resemble the trend lines for American Catholics and Mainline Protestants.” Hebrew Union College’s Steven M. Cohen then explains: “They’re all marked by declining adherents and participation.”
Using data from Pew Foundation studies, Cohen has found that Orthodoxy is growing, and growing younger. The Orthodox movement has 230 ten-year-olds for every 100 fifty-year-olds. The non-Orthodox (Conservative, Reform, and Reconstructionist) have only 70 ten-year-olds for every 100 fifty-year-olds.
