Iran Similar Countries Map

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 Iran

Iran is a Middle Eastern country. However, it is fairly unique in the region, since its people are mostly Shi’ites and natively speak Indo-European languages. The five most similar countries to Iran are all predominately Muslim. The top four use the Arabic script. In addition, these countries all have a dry climate. Furthermore, the governments in these countries are not especially democratic.

  1. Iraq has often been a part of the great empires amassed by Persia throughout history. At present, it is one of the few countries in the world with a majority Shi’ite population. The country also produces a lot of oil and gas, like Iran. The biggest difference is that Iraqis speak Arabic, instead of Persian. Still, both countries have a significant Kurdish population. They also both border the Persian Gulf, although Iran is more mountainous.
  2. Syria is even further to the west of Iran than Iraq. It is one of Iran’s closest allies. Syria even has two Iranian military bases within its borders. They both use Type C electrical outlets, drive on the right, and have standard gauge railroad tracks. In addition, both their governments are authoritarian. The internet and journalists are severely censored there. However, Syria’s laws are generally less conservative than Iran’s.
  3. Afghanistan is most similar country linguistically to Iran. Persian and Dari (the lingua franca of Afghanistan) are essentially the same language. They both use the same writing script as well. Its landscape is also quite similar since it is also a mountainous desert country in the same region. However, Afghanistan is much poorer than Iran. While both countries are predominately Muslim, most Afghans are Sunnis.
  4. Egypt is the most similar country in Africa to Iran. It may not seem like an obvious choice for this list, but both countries have similar conservative Muslim laws. In addition, the governments of both countries are authoritarian. They censor journalists and block many internet sites. Furthermore, the countries have similar standards of living, since they are neither extremely poor or rich.
  5. Azerbaijan is Iran’s neighbor to its north. There is actually a large population of Azeris living in Iran. It is another country whose economy relies on the production of oil and natural gas. Both countries have authoritarian governments. However, Azerbaijan is less conservative. In addition, the countries are completely different linguistically, as Azerbaijan speaks a Turkic language and uses the Latin script. Since Azerbaijan was once part of the Soviet Union, it has more of a Russian influence as well. Although both countries are mostly Shia Muslims, Azeris are far less religious.
  6. Jordan, 7. Turkey, 8. Algeria, 9. Tajikistan, 10. Morocco

  1. These maps are wonderful, thank you for making them! I’d be very interested in seeing Somalia, as it’s consistently least similar to so many countries.

  2. It’s very interesting to see that Egypt is second although the are quite different in culture, politics demography and geography.
    By the way how Egypt is the most similar to Iran politically?
    Egypt has a secular government and Iran has a religious government.
    Egypt is an US ally while Iran is in the Russian-Chinese side. On top of that Egypt is a part of an anti Iranian alliance with the Saudi Arabia and the UAE.

    1. World Policy Center lists Egypt as a religious government, not secular. Both have authoritarian governments. Almost all their laws from abortion to LGBT rights, to prostitution are nearly identical. Its interesting you bring up allies which is somewhat included in which countries receive weapons from each other recently. Egypt got them from Russia, France, and USA, while Iran got them from Russia and China.

      1. Thanks for the comment, maybe after the revolution and the Muslim brotherhood the government has become religious because under Mubarak administration they had a secular government (like Sadam in Iraq or Syria). Even now the leaders of Egypt has no religious background.

  3. By the way it’s very interesting to see that Egypt is the second closest country to Iran but Iran is not the top 10
