30 Least Populated Countries In The World

Geographical isolation, small land areas, and harsh weather all contribute to many of these minute population sizes.

The images that we are used to when we talk about many countries are usually those of excess: large masses of land, numerous roads and buildings, and large groups of people. Particularly, when discussing the populations of countries, people expect such numbers to be in the millions rather the tens of thousands. Nevertheless, there are indeed countries with very small populations that rarely grab our attention in the news, and subsequently not many people are aware of their existence. When you mention the name of a large country with a similarly huge population to any average person on the streets, he or she is likely to have some idea of its existence or even where its located. On the other hand, if you mention a small British territory in the Caribbean to the average person, chances are that he or she will not have any scope of knowledge pertaining to it.

​Smallest National Populations

With a population of 451, the European country of Vatican City has the smallest national population in the world. Fewer than 40,000 people live in Tuvalu, Palau, San Marino, Liechtenstein, and Monaco. Meanwhile, the Marshall Islands, the Northern Mariana Islands, St. Kitts and Nevis, American Samoa, Greenland, and the Cayman Islands each have less than 60,000 people nationwide.

Factors Contributing to Small Population Sizes

The countries that are least populated in the world are often also some of the most isolated. A majority of them are small islands that are expensive or otherwise inconvenient to reach, because the most common conventional means of travel to them is via a private plane or ship. Therefore, fewer people tend to visit or migrate to these locales. There are also countries that are located in places with very harsh weather conditions that do not appeal to many people. Most of the Islands in the West Indies and the Caribbean have very small populations because of the small sizes of their landmasses They can therefore only accommodate a small number of people because of limited space resources. These isolated islands do not present a lot of options to their young populations looking for new challenges and prospects in terms of career development, while faraway images of the skyscrapers of New York or studios of Los Angeles promise far more opportunities. A country like Greenland is covered in snow for most parts of the year, and that kind of weather is not considered ideal by many people, nor conducive to industrial or agricultural development. In many places, a combination of adverse weather conditions and small size has greatly contributed to their small populations. While there are many factors that leave fewer people desiring to migrate to the least populated countries, those listed above are the most common reasons.

Prospects for Growth

Statistics indicate that most people would rather use these less populated places for a remote vacation while continuing to live in populated countries. Aside from a few countries like the Vatican City, Monaco and Liechtenstein which border other European nations, most of the least populated countries are far more isolated and seem inaccessible to most people. There is little likelihood for many of the least populated countries in the world to witness a marked increase in the size of population anytime soon. In fact, many of the reasons that have left them with so few residents are largely unchangeable, and many of those listed are actually losing people as they seek lives elsewhere.
