According to the Pew Report, JW's had the lowest retention rate of any religion in the U.S. at 37% compared to highest rated Hindus retained 84% of their raised in, followed by Jews at 76% and Mormons with a retention rate of 70%. Even the much maligned Catholic Church retains 68% of their raised in members.
A couple of other handy facts from the same Pew Report:
1) JWs are tied for second place for a majority of females in the faith. 60% are female!! (first place are Hindus with 61%)
2) 42% make less than $30,000. This is the second HIGHEST percentage of the poorest cohort of all faiths!
3) JWs have the LOWEST percentage of college graduates and post-graduates of any faith surveyed! (no surprise there).
Though they may be growing at a higher rate than average, JW's cannot hang on to their most important legacy, their children.
