This statistic illustrates the projected growth of major religious groups from 2015 to 2060. In 2060, it is projected that there will be about *** billion Muslims worldwide, compared to *** billion Muslims in 2015.

As of 2010, Christianity was the religion with the most followers worldwide, followed by Islam (Muslims) and Hinduism. In the forty years between 2010 and 2050, it is projected that the landscape of world religions will undergo some noticeable changes, with the number of Muslims almost catching up to Christians. The changes in population sizes of each religious group is largely dependent on demographic development, for example, the rise in the world's Christian population will largely be driven by population growth in Sub-Saharan Africa, while Muslim populations will rise across various regions of Africa and South Asia. As India's population is set to grow while China's goes into decline, this will be reflected in the fact that Hindus will outnumber the unaffiliated by 2050. In fact, India may be home to both the largest Hindu and Muslim populations in the world by the middle of this century.

The majority of Japanese adhere to Shintoism, a traditional Japanese religion focusing on rituals and worship at shrines. In 2021, around 48.6 percent of the total population of Japan participated in Shinto practices. Closely behind is Buddhism, with more than 46 percent of the population adhering to its practices. Most Japanese thus practice both religions. The original ShintoShintoism adherents worship spirits or gods at shrines, often publicly, through rituals and traditions. Shintoism is deeply ingrained in the Japanese culture and way of life, but the number of followers has been decreasing over the past years, as has the number of Japanese who are adhering to any kind of religion. Tradition seems to have to make way for modern attitudes and choices – still the number of people who call themselves Shinto adherents is quite high, even if they do not actively practice it. Everything zen in BuddhismWhile Shintoism seems to become a thing of the past, the number of Buddhists, on the other hand, has been stable over the last decade, and if anything, has only slightly decreased. Japan is, in fact, among the countries with the largest Buddhist communities, right after China, of course, and Thailand. This might be due to Buddhism being able to adapt much easier to modern times and its adherents’ everyday lives, as well as a better PR machine – Buddhism is, after all, also quite popular in the Western world.

The Hajj to Mecca in Saudi Arabia is considered among the world’s largest human gatherings, with over **** million pilgrims in 2025. The Saudi government restricted Hajj to residents in Saudi Arabia only during the COVID-19 pandemic in 2020. The number of Hajj pilgrims dropped to about **** thousand in 2021. Like other religious pilgrimages, Hajj is considered an annual rite of passage to renew one's moral and spiritual connection. Approximately a quarter of the human population identify themselves as Muslims. According to their faith of Islam, it is one of their five religious duties to perform the Hajj at least once in their lifetime. Who are the pilgrims? According to Islamic tradition, any Muslim who has reached maturity is due to perform the Hajj. During the last Hajj season before the COVID-19 pandemic, about two thirds of the pilgrims to Mecca came from outside of the Saudi Arabian Kingdom. The government of Saudi Arabia issues each years’ Hajj visas on a country quota system, based on the size of the Muslim population .     Financial aspects   One main condition for a mature Muslim to qualify to perform the Hajj is to be free of debt and other financial and social obligations. Many Muslims around the world spend a significant amount of their life-savings to be able to make this spiritual journey. As an example, the cost of performing Hajj for a Malaysian Muslim was calculated at about ***** thousand Malaysian ringgits. For first time Hajj pilgrims, the Malaysian government subsidizes more than half of that amount.

In 2022, almost two million Muslim marriages took place in Indonesia, including informal registrations. Under Syariah law, Muslims are permitted to marry once they reach sexual maturity. This has led to a widespread practice of forced child marriage in Indonesia. In September 2019, the Indonesian parliament passed a bill to raise the minimum age of marriage for women from 16 years to 19 years. Financial burden of divorce Forced marriage was cited as a ground for divorce in *** cases in 2022.
