Mapped: A Decade of Population Growth and Decline in U.S. Counties

Visualizing the World’s Most Popular Religions

According to some estimates, there are over 4,000 religions, faiths groups, and denominations that exist around the world today. Researchers and academics generally categorize the world’s religions into five major groups: Christianity, Islam, Buddhism, Hinduism, and Judaism.

This graphic by Chit Chart visualizes the most popular religions around the world, using the latest available data from Index Mundi’s world demographics.

In addition to the five major religious groups, the graphic includes two more categories: one for a collective of Folk religions and another for people who are unaffiliated with a religion.

The Religions with the Most Followers

Although the number of people who follow a religion has decreased in recent decades, 82.8% of the global population still identifies with one of the world’s major religions.

Here’s a breakdown of the most popular religions, ranked by their following as a percentage of the world’s population:

Christianity has the largest following with approximately 31% of the global population. Muslims make up the second-largest religious group, accounting for 23.2% of the world’s population.

Roughly 16.4% of the global population is unaffiliated with a religion. This figure exceeds the percentage of people who identify with Hinduism (15%), Buddhism (7.1%), Folk Religions (5.9%), or Judaism (0.2%).

The World’s Religions from Oldest to Newest

Hinduism is considered the oldest religion in the world, originating in the Indus River Valley (modern-day Pakistan) circa 7000 BCE.

While Judaism came after Hinduism, it is thought to be the oldest of the three monotheistic Abrahamic faiths, making it older than Christianity and Islam.

It began circa 2000 BCE in the Southern Levant (modern-day Israel, Palestine, and Jordan). By contrast, Christianity was founded in the 1st century and began as a movement within Judaism.

Scholars typically date the creation of Islam to the 7th century, making it the youngest of the world’s major religions on this list. Islam was established in Mecca (modern-day Saudi-Arabia).

One religion that’s not included on this list is Sikhism. Founded in the late 15th century, it’s relatively new, especially compared to other religions like Hinduism or Judaism. Yet, despite being new, Sikhism has a large following—according to some estimates, there are over 25 million Sikhs worldwide.

What are Folk Religions?

A folk religion is defined as an ethnic or cultural practice that exists outside the theological doctrine of organized religions.

Lacking sacred texts, Folk religions are more concerned with spirituality than rituals or rites. Examples of Folk religions include Native American traditions, Chinese folk religions, and traditional African religions.

Since Folk religions are less institutionalized, they are especially challenging to measure and often excluded from surveys. With that said, an estimated 5.9% of the global population (approximately 430 million people) practice a Folk religion.

The Fastest-Growing Religions

While Islam is the newest of the big five religions, it’s currently the world’s fastest-growing one too. For context, here’s the estimated percent change among the seven religion categories, between 2015 and 2060:

Islam’s rapid growth means it may surpass Christianity as the world’s largest religion within the next half-century. What’s causing this growth?

According to Pew Research Center, the main reason is simply demographics—on average, Muslim women have 2.9 children, which the average of all non-Muslims is 2.2.

Muslims are also concentrated in Africa and the Middle East, the two regions predicted to have the highest population increases in the next few decades.

Mapping the Migration of the World’s Millionaires

Throughout 2022, a projected 88,000 millionaires will move to a new country, according to the latest Henley Global Citizens Report.

Which countries are these millionaires moving to, and where in the world are they coming from?

This graphic maps the migration of high net worth individuals (HNWIs)—people with a net worth of over US$1 million—showing where rich people are flocking, and where they’re fleeing.

Migration of Millionaires is Back

Before diving into the country-specific data, it’s worth taking a step back to look at overall millionaire migration trends, and how things are changing this year.

2020 saw a drastic drop in the number of millionaire migrants, as pandemic-induced lockdowns kept people from leaving their home countries—and at times, their homes in general.

But as restrictions ease and countries begin to open up their borders again, the migration of millionaires is beginning to gather steam once again:

Below, we’ll dive into which countries are seeing the highest number of HNWI migrants, and which ones are losing the most HNWIs.

Which Countries Are Millionaires Leaving?

There are a plethora of reasons why the ultra-rich move countries. Escaping conflict is one of them, which is why it’s no surprise to see Russia and Ukraine are projected to see some of the biggest emigration numbers by the end of 2022.

Here are the top 10 countries by millionaire outflows:

Figures rounded to the nearest 100.

While Russia is expected to see 15,000 millionaires leaving the country, Ukraine is projected to experience the highest loss in percentage terms—a whopping 42% of its HNWIs could leave the country by the end of 2022.

China could also see a big loss in its millionaire population, with a projected loss of 10,000.
According to Andrew Amoils, Head of Research at New World Wealth, this could be more damaging to the country than in previous years, since general wealth growth in China has declined recently.

Where Are The Ultra-Rich Moving?

The United Arab Emirates (UAE) has become a millionaire magnet, with a projected 4,000 HNWIs flowing into the country by the end of 2022. This influx of ultra-wealthy people is partly because of the country’s accommodating immigration policies that are specially tailored to attract private wealth and international talent.

Here are the top 10 countries that saw millionaire inflows:

Australia continues to attract HNWIs, coming in second behind the UAE. According to New World Wealth, approximately 80,000 millionaires have moved to the Land Down Under in the last two decades.

A few things that attract migrants to Australia are the country’s low costs of healthcare, its lack of inheritance tax, and its generally prosperous economy.
