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.
The United States is a former British colony located in North America. Relatively few countries are like it. The five most similar countries to the United States all have predominately English-speaking populations. In addition, most of the people in these countries have European ancestry and are Christian. They are among the wealthiest nations in the world and have well developed infrastructure, including potable tap water and extensive networks of highways.
Top 10 Places Most Similar to the United States

Still, the United States has had a great influence on Canada due to its close proximity. In fact, they share the longest border between any two countries in the world. Both countries drive on the right, use standard gauge railroad tracks, and Type A,B electrical outlets with the same voltage.
- Australia is another former British colony characterized by a large European immigrant population. Like the United States, their people are more extroverted than other predominately White, English-speaking countries. However, like Canada, it became independent from Britain much later. In addition, it is on the opposite side of the earth so its geography is significantly different.

- United Kingdom originally founded the United States, so it is no wonder that they are high on this list as well. More Americans trace their ancestry back to Britain than any other country. However its government and geography differ from the United States. It is much more densely populated and is not as mountainous. Still, the forests of Great Britain do bear a strong resemblance to Eastern United States, while the landscape of the Western United States is significantly different.
- Ireland also has similar culture and demographics to the United States in part because of its similarity to Britain, but also because 10% of the United States population claims to have Irish ancestry. It is also the only country on this list that has a popularly elected head of state, like the United States, not the Queen of England. However, unlike other English speaking countries on this list, Ireland is mostly Catholic, although they are both relatively religious compared to other predominately White, English-speaking countries.
