Population Density by Country & Calculator 2026

Monaco tops the world at 19,177 people per km² — over 313× the world average of ~61.2/km². The 10 most-dense list is dominated by city-states and small island nations; Bangladesh is the only country with over 100 million people in the top 10. At the opposite extreme, Mongolia has just 2.25 people/km² — vast territory with sparse settlement.

Asia averages over 150.3 people per km² — more than triple the world average of ~61.2/km². Roughly 60% of humanity lives in Asia, on land that's only about a third of Earth's inhabited area. Australia and Oceania, despite vast territory, sit at the bottom because most of the land is either Australian outback or scattered Pacific microstates.

A country's average density understates how dense most people actually live. Dhaka, Mumbai, and Manila exceed 20,000 people per km² — denser than Singapore (~8,000) or Monaco (~19,000) at the country level, despite those being city-states. Even New York and London sit at 4,000–6,000/km² — well above their national averages of ~37/km² and ~280/km².
