The Most Similar Countries to Bulgaria


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 Places Most Similar to Bulgaria

Bulgaria is a European country located on the Balkan Peninsula. Four of the top five countries most similar to Bulgaria speak Slavic languages. The top five countries are mostly Christian. In addition, these countries are all multi-party democracies that use the parliamentary system of government. Furthermore, their climates are temperate and their landscapes are a mix of forests and farmland.

  1. Serbia is located to the west of Bulgaria. Other than being landlocked, its climate and landscape is quite similar to Bulgaria. It is another predominately Orthodox Christian country, however Bulgarian is not mutual intelligible with Serbo-Croatian, although they are closely related. The countries also have a similar standard of living. One difference is that unorganized prostitution is legal in Bulgaria, unlike Serbia. Still, both countries have similar laws, since they both allow abortion and gambling, but do not allow same sex marriages or polygamy.
  2. North Macedonia borders both Bulgaria and Serbia. Macedonian is considered by some to be just a dialect of Bulgarian and both languages use the Cyrillic alphabet exclusively. Like Serbia and North Macedonia, it is mostly Orthodox Christian. However, North Macedonia also has more Albanians and more Muslims than Bulgaria. It also has a lower percentage of farmland and tends to grow more barley and grapes, although their diets are extremely similar.
  3. Romania is another Orthodox Christian nation that borders the Black Sea. It is just to the north of Bulgaria, across the Danube River. There actually have been a few proposals to unify the two countries before. They are among the poorest countries in the European Union. However, linguistically Bulgaria and Romania are far apart since Romania speaks a Romance language and uses the Latin script. In addition, its people are more religious.
  4. Croatia is another Slavic country in the European Union. Both countries have beach resorts that are frequented by many Europeans, although Croatia is on the Mediterranean, not the Black Sea. Another difference is that Croatia is mostly Catholic and does not use Cyrillic. In addition, while soccer is the favorite sport of both countries, basketball and handball are more popular in Croatia. Still, both countries have aging populations and have significantly more females than males.
  5. Slovakia‘s government is especially similar to Bulgaria’s. Both countries have unicameral legislatures and their courts follow Civil Law. They are also both members of NATO and the European Union. Their laws are nearly identical. Both countries allow unorganized prostitution and but do not allow polygamy or same sex marriage.
