{{Cquote|Even without demographic models, survey data since the 1970s show that the percentage of Americans with a “strong” religious affiliation has not declined at all; it is the “weak” that have turned into “[[nones]].” Moreover, immigration brings primarily religious people from the Global South into the Global North. In his earlier book, Kaufmann predicted that America’s secular high-water mark will occur around 2030; in Western Europe, no later than 2070. In Kaufmann’s view, religious identity will largely overpower ethnic identity a century hence, “with seculars and moderates of all backgrounds lining up against the fundamentalist sects.”<ref>[https://www.firstthings.com/article/2019/11/the-future-is-mixed THE FUTURE IS MIXED] by Darel E.
