The U.S. Government estimates the total population at 45.5 million (midyear 2020 estimate). According to a 2019 survey by CONICET, the country’s national research institute, 62.9 percent of the population is Catholic; 15.3 Protestant, including evangelical groups; 18.9 percent no religion, which includes agnostics; 1.4 percent Jehovah’s Witnesses and The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ); 1.2 percent other, including Muslims and Jews; and 0.3 percent unknown. Other sources state Seventh-day Adventists, Baptists, Jehovah’s Witnesses, Lutherans, Methodists, and members of the Church of Jesus Christ together total 3 percent of the population. According to AMIA, there are 220,000 Jews in the country, and the Islamic Center estimates the Muslim population at 800,000 to 1,000,000. Evangelical Christian communities, particularly Pentecostals, are growing, but no reliable statistics are available. There are also small numbers of Baha’is, Buddhists, and adherents of indigenous religions.
