The population continued to grow, peaking at nearly 300 families in both congregations in 1989. Numbers fell in the 1990s and have stabilized in recent years at approximately 200 families. The total size of the Jewish population in 2001, however, was 1555. As a result, there were many Jewish residents who are unaffiliated, who have not joined either synagogue.
