Have you ever wondered how similar or different two countries are? The Country Similarity Index attempts to quantify how similar countries are to each other relative to other countries. The index is a statistically-based way to measure this. It weighs equally five major aspects of countries: their demographics, culture, politics, infrastructure, and geography. The methodology is exactly the same for each country. The research combines 1,000 different data points to arrive at the conclusions.
Top 10 Countries Most Similar to South Korea
South Korea is an East Asian country that borders the North Pacific Ocean. Very few countries are like it. The four most similar countries all border the Pacific Ocean. Their agricultural lands produce a large amount of rice. In addition, these four countries usually have many high-rises and skyscrapers in their large cities. They are also all relatively mountainous countries. Furthermore, these countries tend to have many irreligious people.
- Japan annexed South Korea in 1910 and occupied the country until the end of World War II. The demographics and geography of these countries are significantly similar. Both also share similar sports culture, being most interested in baseball and soccer, while also excelling in the Olympics. However, Korea is more westernized. It has a large percentage of Christians. Furthermore, most Korean males are circumcised, unlike in Japan. The countries both have highly developed infrastructure, however Japan drives on the left and uses different electrical outlets and voltage.
- Taiwan was another protectorate of Japan until the end of World War II. South Korea and Taiwan are densely-populated mountainous lands whose agriculture is primarily rice, although Taiwan is more tropical. In addition, the countries have a similar standard of living. Taiwan drives on the right, like South Korea, but it uses Type A, B electrical outlets like Japan.
- North Korea is the only other country that speaks Korean and uses its unique writing system, Hangul. However, there are huge political and technological differences between South Korea and North Korea. While South Korea is a two-party democracy, North Korea is a one-party authoritarian dictatorship. In addition, North Korea is far poorer and has less developed infrastructure. Still, considering that the countries share the same peninsula, their geography is similar, although North Korea is less densely populated.

One big difference is that China has a lot more desert and also a wider variety of biomes. Like North Korea, the country is controlled by a one-party authoritarian government, but it is less extreme.
- Slovenia is the only European country in the top five, although it has a similar score to other European countries, since they generally have similar technology and climate. Both countries are not especially religious, but both have many Christians. Unlike Japan, South Korea adopted standard Continental European infrastructure since they drive on the right, use the standard railroad gauge, and have Type C, F electrical outlets with a similar voltage.
