Russia or Nigeria? Japan or Mexico? Guess which country has the larger population.
Over 60% of the world's population lives in Asia — but can you tell which individual countries are bigger than you think? Population rankings are full of surprises. Bangladesh has more people than Russia. Nigeria has more people than Brazil. And tiny Singapore packs nearly 6 million people into an area smaller than New York City. This quiz pits countries against each other and asks you to guess which one has more people.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Questions range from head-to-head country comparisons to facts about population density, megacities, and demographic trends. Your final score comes with a performance tier and shareable results.
You'll discover which countries are far more populated than their geographic size suggests, learn about the fastest-growing populations on Earth, and challenge your assumptions about how many people live in Europe versus Africa. Population geography is one of the most surprising branches of the subject — and most people score lower than they expect.

Niger consistently has one of the highest population growth rates in the world at around 3.7% per year, driven by a fertility rate of nearly 7 children per woman. Several other sub-Saharan African nations, including Chad, Mali, and the Democratic Republic of Congo, also have growth rates above 3%.
The world population reached 8 billion in November 2022 and is estimated at approximately 8.2 billion as of 2025. The UN projects it will peak at around 10.3 billion in the 2080s before gradually declining.
