The U.S. government estimates the total population at 27.92 million (midyear 2019 estimate). According to 2019 Mozambique government census data, 26.2 percent of citizens are Roman Catholic, 18.3 percent Muslim, 15.1 percent Zionist Christian, 14.7 percent evangelical/Pentecostal, 1.6 percent Anglican, and 4.7 percent Jewish, Hindu, and Baha’i. The remaining 13.4 percent did not list a religious affiliation. According to Christian and Muslim religious leaders, a significant portion of the population adheres to syncretic indigenous religious beliefs, characterized by a combination of African traditional practices and aspects of either Christianity or Islam, a category not included in government estimates. Muslim leaders continued to state that their community accounts for 25-30 percent of the total population, a statistic frequently reported in the press. The Muslim population is concentrated in the northern part of the country.

The U.S. government estimates the total population at 14.5 million (midyear 2019 estimate). According to the 2015 nationwide Demographic and Health Survey conducted by the government statistics agency, 86 percent of the population is Christian, 11 percent reports no religious affiliation, less than 2 percent adheres uniquely to traditional beliefs, and less than 1 percent is Muslim. According to the survey, of the total population, 37 percent is Apostolic, 21 percent Pentecostal, 16 percent other Protestant, 7 percent Roman Catholic, and 5 percent other Christian.

While there are no reliable statistics regarding the percentage of the Christian population that is syncretic, many Christians also associate themselves with traditional practices, and religious leaders reported a continued increase in syncretism.

Most of the Muslim population lives in rural areas and some high-density suburbs, with smaller numbers living in other suburban neighborhoods. There are also small numbers of Greek Orthodox, Jews, Hindus, Buddhists, and Baha’is.
