The Vatican City, often called the Holy See, has the smallest population worldwide with only 510 inhabitants by 2022 statistics. This is also the smallest country in the world by size.
If you do not prefer to consider Vatican City as a country due to social context of your question, Niue is the second least populated country in the world with a population of 1,610 people in 2021 statistics.<|im_end|>
