The wide variety of peoples inhabiting Georgia has meant a correspondingly rich array of active religions in the country. Today most of the population in Georgia practices Orthodox Christianity, primarily in the Georgian Orthodox Church, whose faithful make up 83.4% of the population. Around 2.9% of the population follow the Armenian Apostolic Church (Oriental Orthodoxy), almost all of which are ethnic Armenians. Adherents of Islam make up 10.7% of the population and are mainly found in the Adjara and Kvemo Kartli regions and as a sizeable minority in Tbilisi. Catholics of the Armenian and Latin churches make up around 0.8% of the population and are mainly found in the south of Georgia and a small number in Tbilisi. Protestants also make up less than 1%.
