Smallest countries worldwide 2020, by land area

The smallest country in the world is Vatican City, with a landmass of just 0.49 square kilometers (0.19 square miles). Vatican City is an independent state surrounded by Rome. Vatican City is not the only small country located inside Italy. San Marino is another microstate, with a land area of 60 square kilometers, making it the fifth-smallest country in the world. Many of these small nations have equally small populations, typically less than half a million inhabitants. However, the population of Singapore is almost six million, and is the twentieth smallest country in the world with a land area of 726 square kilometers. In comparison, Jamaica is almost eight times larger than Singapore, but has half the population.

世界面积最小的国家为梵蒂冈城，其国土面积仅为0.49平方公里（0.19平方英里）。梵蒂冈城是一个独立的主权国家，被罗马所环绕。梵蒂冈城并非意大利境内唯一的小国，圣马力诺亦是微型国家之一，国土面积达60平方公里，位居世界第五小国。众多此类小型国家拥有同样稀少的居民，通常人口不足五十万。然而，新加坡的人口接近六百万，尽管国土面积为726平方公里，仍位居世界第二十小国。相较之下，牙买加的面积是新加坡近八倍之大，但其人口却只有新加坡的一半。
