There are 57.5 million square miles of land on Earth, yet 95% of the planet’s human population inhabits only 10% of that land, according to the World Bank’s 2009 World Development Report.
To identify the least densely populated countries on Earth, 24/7 Wall St. reviewed the United Nations 2019 World Population Prospects.
Climate and geography play a significant role in population density. The most sparsely populated areas on Earth tend to be those with limited access to fresh water, including deserts and arctic zones, and those with dense impassable rain forest, rugged mountains, or that are isolated from continental zones by miles of ocean.
The estimated populations for 2020 are from the World Population Prospects Report. Comparisons of estimated population, square miles, and population growth are between the 50 least densely populated countries on Earth, as opposed to all countries.
At the time of the first World Population Day — July 11, 1989 — about 5.25 billion people trod the Earth. Now, about 7.7 billion of us share the globe, and the number is expected to increase to 8.5 billion by 2030 — and these are the countries with the faster-growing populations around the world.
