Christian population by country (2020)


By 2020, it is estimated that there will be 2.55 billion Christians, representing 33% of the world’s population. This is according to a report by the Center for the Study of Global Christianity, Christianity in its Global Context, 1970–2020: Society, Religion, and Mission. The largest Christian populations will be found in the United States (263 million), Brazil (190), China (148), Mexico (120), Russia (118), Philippines (100), Nigeria (96), DR Congo (81), India (67), and Ethiopia (61). The map above shows Christian population (millions) by country as represented by proportional circles. Countries with less than 1 million Christians are marked with a gray dot. Of particular interest is the growth of Christianity in the largest country of the world by population: China. The percentage of the population adhering to Christianity has risen “from 0.1% in 1970 to 7.9% in 2010 and 10.6% in 2020.” China’s estimated Christian population of 148 million in 2020 would make it the third-largest in the world.
