Religion in Austria
Catholicism is the largest religion in Austria, representing 57.9% of the total population in 2017. The Catholic Church's governing body in Austria is the Austrian Conference of Catholic Bishops, made up of the hierarchy of the two archbishops (Wien, Salzburg), the bishops and the abbot of territorial abbey of Wettingen-Mehrerau. Nevertheless, each bishop is independent in his own diocese, answerable only to the Pope. The current president of the Conference of Catholic Bishops is Cardinal Christoph Schönborn. Schönborn belongs to the Central European noble family of Schönborn. Although Austria has no primate, the archbishop of Salzburg is titled "Primus Germaniae" (Primate of Germany).

The most recent Pew Research Center, found that in 2015, 51% of the population of Estonia declared itself Christians, 45% religiously unaffiliated—a category which includes atheists, agnostics and those who describe their religion as "Nothing in Particular", while 2% belonged to other faiths. The Christians divided between 25% Eastern Orthodox, 20% Lutherans, 5% other Christians and 1% Roman Catholic. While the religiously unaffiliated divided between 9% as atheists, 1% as agnostics and 35% as Nothing in Particular. 
The largest religious denomination in the country was Lutheranism, adhered to by 160,000 Estonians (or 13% of the population) according from 2000 census, principally ethnic Estonians. Other organisations, such as the World Council of Churches, report that there are as many as 265,700 Estonian Lutherans. Additionally, there are between 8,000–9,000 members abroad. But however since 2011 census that Eastern Orthodoxy has surpassed Lutheranism by 16.5% or 176,773 of Estonian population as more native Estonians abandoning Lutheranism to favor without having religion and some they converted to Eastern Orthodoxy.
