Extremely Different Countries with the Same Religion

Most of the time, countries that practice the same religion are similar. However, there are some exceptions. A few pairs of countries are part of the same religious denomination, but have little else in common. A list of these countries was developed by analyzing the data from the Country Similarity Index, that weighs equally five major aspects of countries: their demographics, culture, politics, infrastructure, and geography. For the purposes of this article, both two-thirds of the religious people in both countries must be part of the same denomination.

Most people in Denmark and Papua New Guinea are Protestant Christians, although Danish people tend to be less religious, while Papuans tend to practice animism and ancestor worship alongside their Christian beliefs. Papua New Guinea was colonized by both Germany and the United Kingdom, two predominately Protestant countries. Over the past 100 years, Western missionaries worked hard to convert Papuans to Christianity.

However, these countries are vastly different. Papua New Guinea is on a tropical island in the Pacific Ocean, while Denmark is located in Europe and has a colder climate. Moreover, Denmark is mostly agricultural land and has few forests, in contrast to Papua New Guinea. While Papua New Guinea is quite mountainous, Denmark’s terrain is extremely flat. Furthermore, the majority of people in Papua New Guinea have Melanesian ancestry. Papua New Guinea’s infrastructure is also far less advanced than Denmark’s. Furthermore, the technology standards are far different, Papua New Guinea drives on the left and uses Type I electrical outlets, unlike Denmark.

In contrast, Ireland has a much cooler climate and much of its land is used as pastures. Furthermore, Ireland’s infrastructure is also significantly more advanced than Equatorial Guinea’s. They also have different technology standards, since Ireland drives on the left and uses Type G electrical outlets. While Ireland is a multi-party democracy, Equatorial Guinea is an authoritarian state ruled by one party.

Most people in Cyprus and Russia are Eastern Orthodox Christians. However, in part due to the practice of state atheism in the Soviet Union, Russians tend to be less religious than Cypriots. Both countries also have a significant percentage of Muslims as well.

However, the climate in these countries is vastly different. While Russia is one of the coldest countries on average, Cyprus has a Mediterranean climate. Russia is also more densely forested but less densely populated. These countries also use different alphabets. Their technology standards are significantly different as well since Cyprus was occupied by the United Kingdom, so the country drives on the left and uses Type G electrical outlets. Furthermore, Cyprus is more democratic and its government does less censorship than Russia.

Most people in Saudi Arabia and Sierra Leone are Sunni Muslims. Islam slowly spread from the Arabian peninsula to West Africa through missionaries and merchants. In fact, in 1950, less than 50% of people in Sierra Leone were Muslim, but the religion as grown since then, despite British colonialism.

However, Sierra Leone has a tropical climate and is a densely forested, unlike Saudi Arabia, which has a much drier climate. Most Saudi Arabians have Caucasian ancestry, while most people in Sierra Leone have Sub-Saharan African ancestry. They also speak completely unrelated languages and use different writing systems.

Most people in Laos have East Asian ancestry, while most people in Sri Lanka have South Asian ancestry. In addition, Sri Lanka is an island, while Laos is landlocked. Their technology standards are different as well. Sri Lanka drives on the left and uses Type G electrical outlets, unlike Laos. Another difference is that the government of Laos is less democratic and is lead by a single party.
