Note: Preliminary analysis suggests that
about 60% of people
who try Scientology do only a single course or service, that 80% of new members
become inactive within 2 years, and that 65% of those who
reach the level of Clear become inactive within a year after doing
so. The older a list, the more likely that a person listed on it is
no longer involved in Scientology.
