The country is multiethnic, with a long tradition of tolerance and secularism. Since independence, the number of mosques and churches has increased greatly. However, the population is sometimes wary of minority religious groups and groups that proselytize. There were several reports of citizens filing complaints with authorities after their family members became involved with such groups. Leaders of the four religious groups the government considers "traditional" — Islam, Russian Orthodoxy, Roman Catholicism, and Judaism — reported general acceptance and tolerance that other minority religious groups did not always enjoy.
