Are you curious which countries in the world are considered to be Third World countries? There are many countries in the world considered Third World countries, although getting an exact list of these countries is difficult because of disagreements about exactly what the term “Third World country” means.

In fact, the very term Third World country is falling out of use and being replaced with other terms such as “least developed countries” or more preferably “developing countries”. In order to make any progress with listing third world/developing countries, let’s first discuss what the term developing country means and what countries qualify as developing countries.

Defining The “Third World”

The term third world country was initially created during the Cold War when it was applied to countries that were not aligned with one of the two major political spheres at the time. The first and second world countries belonged to either the North Atlantic Treaty Organization (or NATO) or the Communist bloc. At this time, the first world countries were nations found in Western Europe, the United States, South Korea, Japan, and Canada. Meanwhile, the second world countries were the Soviet Union and its allies states, as well as Cuba and China. Finally, the Third World countries were countries which did not align with either of these groups and were neutral, having their own political and economic structures uninfluenced by either of the two groups.

After the fall of the Soviet Union, with its territories becoming their own independent nations, the use of the term Third World shifted. In current times the term Third World country is used to describe a nation that lacks the societal, political, and economic development of the First World or Second World nations. Essentially, the term Third World country is used to describe nonindustrialized and economically struggling countries, as well as countries that have just recently industrialized.

Do in part to the confusion over the definition of the term “Third World”, as well as a desire to be considerate of citizens in “Third World” countries, the preferred term for countries in the process of developing is, as you might imagine, “developing countries”. The United Nations also maintains a list of countries which have the least economic, political, and technological development, describing them as the Least Developed Countries or LDCs.


The criteria for being categorized as an LDC is often shifting since the nations of the world are always developing. Because of this, what nations are classified as LDCs often shift as well. As of the most recent classification, the LDC nations include: Afghanistan, Bangladesh, Cambodia, Guinea, Haiti, and Laos, among others. One does not need to be one of the globe’s Least Developed Nations to be considered a developing nation, and for this reason, the list of developing nations is much larger than the list of Least Developed Nations.

This category of developing countries includes an extremely diverse array of individuals, groups, and cultures. To get an idea of how different nations included in the list of developing nations can be from one another, let’s take a look at just a few of the countries included in the list of the developing nations.
