The U.S. government estimates the total population at 4.2 million (midyear 2020 estimate). According to the 2011 census (the most recent), 86.3 percent of the population is Catholic, 4.4 percent Serbian Orthodox, and 1.5 percent Muslim. Nearly 4 percent identify as nonreligious or atheist. Other religious groups include Jews, Protestants, and other Christians. According to the World Jewish Congress, there are approximately 1,700 Jews.

Religious affiliation correlates closely with ethnicity. Ethnic Serbs are predominantly members of the SOC and live primarily in cities and areas bordering Serbia and Bosnia and Herzegovina. Most members of other minority religious groups reside in urban areas.

Because religion and ethnicity are often closely linked, it was difficult to categorize many incidents as being solely based on religious identity.

SOC representatives anecdotally reported increased incidents targeting individuals of Serbian ethnicity compared with 2019, including physical and verbal attacks, especially in Vukovar, a site of intense fighting during the war in the 1990s. They said, however, it was unclear to what extent religious motivations played a part.

According to the Ombudsperson’s Office, the Croatian Bishops’ Conference complained of what it said were sensational or untrue media articles regarding the Catholic Church. As in recent years, members of some Jewish groups reported hate speech, especially on the internet, and incidents such as graffiti on Jewish-owned buildings. Representatives of the Jewish Community of Zagreb expressed concerns regarding the inappropriate use of Ustasha insignia in public.

On February 4-5, the country’s Islamic leaders and the Muslim World League, in cooperation with the Croatian Conference of Catholic Bishops, organized an international conference entitled “Human Fraternity as the Foundation of Peace and Security in the World,” focusing on world peace and coexistence. The conference was held under the auspices of the country’s EU presidency. At the event, the mufti of the Islamic community, Aziz Hasanovic, said that there was no alternative to religious dialogue, highlighting the value of systematic dialogue between the Islamic community and Catholic Church. Then-President Kolinda Grabar-Kitarovic said, “This valuable initiative was an opportunity for Croatia to present itself as a country that promotes the highest standards of religious rights and dialogue.”
