Which Countries are Most Similar to Spain?


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. The index weights equally five major aspects of countries: their demographics, culture, politics, technology, and geography. In addition each aspect was roughly balanced evenly between quantity/percentage and quality/type. See this post for a full explanation: https://objectivelists.home.blog/2020/05/30/country-similarity-index/

Similar to other Catholic, Western European countries

Many countries are similar to Spain. The top 5 countries are all in the European Union and have a majority Catholic population. Although most Latin American countries speak Spanish, only Chile, Argentina, and Uruguay are significantly similar. Most Latin America countries are located in sparsely populated rainforests, in contrast to the chaparral landscape of Spain. Furthermore, Latin American countries tend to have a high diversity of ancestries, unlike Spain. It is also wealthier and more developed than all the Latin America countries.

  3. France is the only other country in Europe that borders both the Atlantic and the Mediterranean. It has roughly the same population density and pollution. Like Italy and Spain, it is also is strong in soccer. However, France has a more diverse population, since it has more Muslims and Africans. Furthermore, France’s climate is wetter and cooler.
  4. Belgium was once known as Spanish Netherlands, since it was ruled by the Habsburgs for over 100 years. The two countries governments are quite similar since they are both constitutional democracies with similar liberal laws. Unlike Portugal, France, and Italy, Belgians drink more beer than wine, like the Spanish. Still Belgium is more north and significantly denser in population.

  1. How could Spain has no Latin American countries in its top 5. I would definetly said Puerto Rico or Cuba rather than France. On the other hand, take into account that Spain was once under muslim domination and yet the least common countries are all muslims, so no. I’ll say the least similar country to Spain would be North Korea, Kazakhstan or even South Sudan!
