Christianity is the major religion in numerous African countries. As of 2024, around 96 percent of the population of Zambia was Christian, representing the highest percentage on the continent. Seychelles and Rwanda followed with roughly 95 percent and 94 percent of the population being Christian, respectively. While these countries present the highest percentages, Christianity was also prevalent in many other African nations. For instance, in South Africa, Christianity was the religion of nearly 85 percent of the people, while the share corresponded to 71 percent in Ghana. Religious variations across Africa Christianity and Islam are the most practiced religions in Africa. Christian adherents are prevalent below the Sahara, while North Africa is predominantly Muslim. In 2020, Christians accounted for around 60 percent of the Sub-Saharan African population, followed by Muslims with a share of roughly 30 percent. In absolute terms, there were approximately 650 million Christians in the region, a number forecast to increase to over one billion by 2050. In contrast, Islam is most prevalent in North Africa, being the religion of over 90 percent of the population in Algeria, Morocco, Tunisia, and Libya. Christianity in the world As opposed to other religions, Christianity is widely spread across continents worldwide. In fact, Sub-Saharan Africa, Latin America and the Caribbean, and Europe each account for around 25 percent of the global Christian population. By comparison, Asia-Pacific and North America make up 13 percent and 12 percent of Christians worldwide, respectively. In several regions, Christians also suffer persecution on religious grounds. Somalia and Libya presented the most critical situation in Africa in 2021, reporting the strongest suppression of Christians worldwide just after North Korea and Afghanistan.

The global population of Buddhists is projected to slightly increase up until the year 2030, at which point it will begin a gradual decline. In terms of its share of total world population, however, Buddhism has already seen a decline from over seven percent in 2010, with this being projected to decline further to close to five percent in 2050. This decline is related to Buddhism being popular in countries whose populations are in a natural decline, such as Japan or South Korea (and Thailand in the near future), as well as demographic developments in countries that have a policy of state atheism, such as China or Vietnam.While this decline in its traditional regions of influence in East and Southeast Asia will cause an aggregate fall in the number of Buddhists, there is likely to be some growth in other regions of the globe, such as Western European and North American countries, where the popularity of the ideas of Buddhism have grown in influence in recent decades.
