World Facts — Smallest Country by Population As per commonly cited global statistics for sovereign states, which country is the smallest in the world in terms of total population?

Introduction / Context:
This general knowledge question asks you to identify the world’s smallest country by population. Competitive exams often test awareness of extreme facts (largest/smallest by area, population, height, etc.). Vatican City is well known for being not only the smallest by area but also by population when counting sovereign states.

Given Data / Assumptions:

• The comparison is among independent, sovereign states.
• We focus on widely accepted contemporary figures rather than temporary fluctuations.
• Microstates in Europe and Oceania (e.g., Vatican City, Monaco, Nauru, Liechtenstein) are typical distractors in such questions.

Concept / Approach:
The key is to distinguish between “small area” and “small population,” and to remember which microstate leads both categories. While several microstates have tiny populations, Vatican City stands out with a population generally under one thousand residents, primarily clergy, Swiss Guards, and officials. The others listed, though small, have populations in the tens of thousands (Monaco) or several thousands (Nauru, Liechtenstein).

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

• Monaco: Densely populated microstate with a far larger population than Vatican City.
• Nauru: Small island country but has a population in the thousands.
• Liechtenstein: Alpine microstate with a population in the tens of thousands.

Common Pitfalls:
Confusing “smallest by area” with “least populated.” Vatican City is smallest on both counts, but some examinees mistakenly pick Monaco due to its extreme density.

Final Answer:
Vatican City
