David Kinnaman comments: The ages of eighteen to twenty-nine are the black hole of church attendance; this age segment is “missing in action” from most congregations. . . . Overall there is a 43 percent drop-off between the teen and early adult years in terms of church engagement. These numbers represent about eight million twentysomethings who were active churchgoers as teenagers but who will no longer be particularly engaged in church by their thirtieth birthday.[9]
