9 Least Populated Countries in the World in 2025
Some countries are so small in population that they have fewer residents than many towns or cities. Mostly island nations or microstates, these countries are celebrated for their peaceful lifestyles, scenic landscapes, and unique cultures. Despite their size, they maintain distinct governance, traditions, and economies, often relying on tourism or specialized industries. In 2025, these nine nations stand out as the least populated in the world:
1. Vatican City – The world’s smallest country by population and land area, home to roughly 800–880 people. Nestled within Rome, it is the spiritual heart of the Catholic Church, attracting millions to St. Peter’s Basilica and the Vatican Museums.
2. Niue – A South Pacific island with 1,800–1,900 residents, known for limestone cliffs, sea caves, coral bays, and crystal-clear waters—ideal for nature lovers.
3. Tuvalu – With 10,000–11,000 people, this Polynesian archipelago offers calm island life, lagoon beaches, and rich marine biodiversity, particularly at the Funafuti Marine Conservation Area.
4. Nauru – Located in Micronesia, Nauru has 12,000–13,000 residents. Visitors can explore the Moqua Caves, coastal cliffs, and golden beaches of Anibare Bay.
5. Cook Islands – Home to 14,000–17,000 people, the islands are known for tropical scenery, vibrant culture, lagoon cruises, and a laid-back lifestyle.
6. Palau – This western Pacific nation has nearly 18,000 residents and is famous for its rock islands, limestone formations, coral reefs, and turquoise waters.
7. San Marino – With about 34,000 people, this European microstate in the Apennines is known for medieval towns, cobbled streets, and historic hilltop fortresses.
8. Marshall Islands – Home to roughly 42,800 residents, it offers white sandy beaches, lagoon activities, and the UNESCO-listed Bikini Atoll with World War II shipwrecks.
9. Liechtenstein – A small Alpine country with nearly 39,000 residents, Liechtenstein is known for its castles, mountain scenery, and strong financial sector.
These countries show that population size doesn’t determine a nation’s culture, natural beauty, or global significance.
