 Know about the least populated countries on ‘World Population Day’
While increasing population is one of the alarming global issues, there are a few countries where population doesn’t even make it to fifty thousand people. Geographical isolation, small land areas, and harsh weather all contribute towards making these nations less populated.

On the occasion of World Population Day celebrated by United Nations, let’s take a tour of 8 least populated countries in the world recognized by UN.

Vatican City

With a population of around 1,000 people, Vatican City is the least populated country in the world. Interestingly, Vatican City is also the smallest country in the world by land area at 0.17 square miles (0.44 square km). The country is enclosed within the Italian city of Rome, and is ruled by the Pope. The citizens residing within the country are either clergy or state officials or members of the Swiss Guard. Its population usually doubles in summers due to the influx of tourists visiting this world’s famous tourist spot.


The second country to make it to the list of the least populated countries is Tuvalu. It is an island country located in Central Pacific in Polynesia, north of Fiji.  It is situated midway between Hawaii and Australia. Having three reef islands comprising 10 square miles of area, Tuvalu has a population more than 11,000. It is interesting to note that Queen Elizabeth II is still the reigning the monarch here and British flag still appears in the top left corner of the official Tuvalu flag.

Located in Pacific Ocean, Palau is another group of islands to make the list. The country has a total of 340 islands for just 21,097 people.

San Marino

San Marino is a scenic European country situated with north-central Italy. Stunning landscapes and mountains are surrounding this beautiful country, thus making it one of the famous European tourist spot. With an estimated population of 33,400 people, the country is spread in an area of 61.2 square km.


Monaco is neither a Kingdom nor a Republic, but a Principality, yet it has been granted full United Nations membership and is a fully recognized country. With a French-speaking population, Monaco has a total of around 37,623 people spread across 2.02 square km. Monaco is not officially a part of the European Union either, but it does participate in certain EU policies, including customs and border controls. The country is famous for its stunning harbor, Monte Carlo Casino and its grand prix circuit. Monaco also has a local football team that plays in the French League and was a runner-up in the 2004 Champions League.


One of only two official ‘doubly-landlocked’ countries in the world, Liechtenstein has a slightly higher population than Monaco, and the pair often switches positions as more or less populated. Currently, its population comprises 38,547 people spread across 160 square km. It borders only Switzerland and Austria, neither of whom have a coastline.

Marshall Islands

The Marshall Islands are a single country comprising 1,000 islands, most of which are uninhabited. The country is part of the larger island group of Micronesia, but only geographically, as it is a separate political power and is a recognized UN member. The estimated population is 53,066 out of which 28,000 live in Majuro Island, the capital.
