Year-of-Entry Distribution

The following table displays the distribution of our members by year of entry into Mensa. Please note that the actual number of members that Mensa Switzerland had in these years is higher, because in this table only members who are still members today are counted. Nevertheless, the numbers can give you some indication of the speed at which Mensa Switzerland was growing at various times. In percentage terms, Mensa Switzerland underwent a particularly rapid expansion in the five years from 1998 to 2002.
