This is the best (and simplest) world map of religions

China and India are huge religious outliers

A picture says more than a thousand words, and that goes for this world map as well. This map conveys not just the size but also the distribution of world religions, at both a global and national level.

Strictly speaking it’s an infographic rather than a map, but you get the idea. The circles represent countries, their varying sizes reflect population sizes, and the slices in each circle indicate religious affiliation.

The result is both panoramic and detailed. In other words, this is the best, simplest map of world religions ever. Some quick takeaways:

Christianity (blue) dominates in the Americas, Europe and the southern half of Africa.
Islam (green) is the top religion in a string of countries from northern Africa through the Middle East to Indonesia.
India stands out as a huge Hindu bloc (dark orange).
Buddhism (light orange) is the majority religion in South East Asia and Japan
China is the country with the world’s largest ‘atheist/agnostic’ population (grey) as well as worshippers of ‘other’ religions (yellow).

The Americas are (mostly) solidly Christian

But the map – based on figures from the World Religion Database (behind a paywall) – also allows for some more detailed observations.

Yes, the United States is majority Christian, but the atheist/agnostic share of its population alone is bigger than the total population of most other countries, in the Americas and elsewhere. Uruguay has the highest share of atheists/agnostics in the Americas. Other countries with a lot of ‘grey’ in their pies include Canada, Cuba, Argentina and Chile.
All belief systems represented on the scale below are present in the US and Canada. Most other countries in the Americas are more mono-religiously Christian, with ‘other’ (often syncretic folk religions such as Candomblé in Brazil or Santería in Cuba) the only main alternative.
Guyana, Suriname and Trinidad & Tobago are the only American nations with significant shares of Hindus, as well as the largest share of Muslim populations – and consequently have the lowest share of Christians in the Americas (just under half in the case of Suriname).

The second-biggest religious affiliation in Europe isn’t Islam, but ‘none’.

Lots of grey area in Europe

Christianity is still the biggest belief system in most European countries, but the atheist/agnostic share is strong in many places, mainly in Western Europe, but especially in the Czech Republic, where it is close to half the total.
Islam represents a significant slice (and a large absolute number) in France, Germany and the UK, and is stronger in the Balkans: The majority in Albania, almost half in Bosnia and around a quarter in Serbia (although that probably indicates the de facto independent province of Kosovo).

Islam in the north, Christianity in the south

Israel is the world’s only majority-Jewish state (75%, with 18% Muslim). The West Bank, shown separate, also has a significant Jewish presence (20%, with 80% Muslim). Counted as one country, the Jewish majority would drop to around 55%.
Strictly Islamic Saudi Arabia, but also some of its neighbors in the Gulf, have significant non-Muslim populations – virtually all guest workers and ex-pats.
Nigeria, due to its large population and even split between Islam and Christianity, has more Muslims and more Christians than most other African nations.

Close neighbors India, Bangladesh and Myanmar each have a different majority religion.

Different majorities across Asia

Because countries are sized for population rather than area, some are much bigger or smaller than you’d expect – with some interesting results: There are more Christians in Muslim-majority Indonesia than there are in mainly Christian Australia, for example.
Hindus are a minority everywhere outside India, except in Nepal.
North Korea is shown as three-quarters atheist/agnostic, but this is debatable, on two counts. In what is often referred to as the last Stalinist state on Earth, religious adherence is probably underreported. And the state-sponsored ideology of ‘Juche’, although in essence based on materialism, makes some supernatural claims. For instance: despite having died in 1994, Kim Il-sung was declared ‘president for eternity’ in 1998.

Of course, clarity comes at the cost of detail. The map bands together various Christian and Islamic schools of thought that don’t necessarily accept each other as ‘true believers’. It includes Judaism (only 15 million adherents, but the older sibling of the two largest religious groups) yet groups Sikhism (27 million) and various other more numerous faiths in with ‘others’. And it doesn’t make the distinction between atheism (“There is no god“) with agnosticism (“There may or may not be a god, we just don’t know“) *.

And then there’s the whole minefield of nuance between those who practice a religion (but may do so out of social coercion rather than personally held belief), and those who believe in something (but don’t participate in the rituals of any particular faith). To be fair, that requires more nuance than even a great map like this can probably provide.

*: Definitions matter, but definitions vary. The ones above, equating ‘atheism’ with a rejection of the belief in god and ‘agnosticism’ as the mere doubting of his existence, may be common, but not necessarily precise. Merriam-Webster defines atheism as “a lack of belief or a strong disbelief in the existence of a god or any gods”. Many in the atheist community subscribe to this definition, which avoids any specific claims to truth (such as “there is no god”).

As one reader clarifies, the difference between ‘knowing’ there is no god and ‘not knowing’ there is no god can be expressed by the adjectives ‘gnostic’ and ‘agnostic’ (both from the Greek root ‘gnosis’, i.e. ‘knowledge’): “A gnostic atheist is making a truth claim that there is no god and does not believe in a god; an agnostic atheist says there is no proof either way and does not believe in a god. They are both atheists because they both hold the position that they don’t believe in any god(s).”

Another reader offers a slightly different take: “The misunderstanding of what the word (‘atheist’) means to people who actively call themselves (thus) is at the root of a lot of the arguments between believers and non-believers. ‘Agnosticism’ is the opposite of ‘gnosticism’, the knowledge of the existence of gods. Most atheists are agnostics, I myself would say I’m an agnostic atheist. As opposed to most believers who would be either gnostic theists or agnostic theists.”
