The 30 Least Densely Populated Countries in the World

The 30 Least Densely Populated Countries in the World

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.

19. Russia
> Population density: 23 people per square mile
> Est. population 2020: 145,934,462 (2nd largest)
> Square miles: 6,323,116 (the largest)
> Population growth 2015-2020: 0.1% (2nd slowest)

The largest country on Earth, Russia encompasses over 6 million square miles. Much of the northern forests are cold enough to be uninhabitable, and most of the population is gathered in the western and southern parts of the country. One major blow to the population of the country was World War II, when the Soviet Union lost an estimated 26.6 million people. The echo of this generation gap circles back around every 25 years or so, when the descendants of those who survived don’t reproduce enough to keep the population stable.

> Square miles: 240,533 (22nd largest)
> Population growth 2015-2020: 1.4% (25th fastest)

The Central African Republic is a landlocked country nearly the size of Texas. Its population has quadrupled since the 1960’s, but ongoing political upheaval, underdevelopment, war, and poverty have all but halted population growth. Deaths from treatable diseases reflect the rampant poverty and lack of health care infrastructure in many areas, especially the diamond-mining region.

16. Kazakhstan
> Population density: 18 people per square mile
> Est. population 2020: 18,776,707 (13th largest)
> Square miles: 1,042,355 (6th largest)
> Population growth 2015-2020: 1.3% (23rd slowest)

The world’s largest landlocked country, Kazakhstan is largely arid and semi-arid steppe. Many areas of the country are radioactive or toxic due to a history of Soviet arms testing. The population centers are clustered around urban areas in the north and south, as the interior of the country is the most arid.

> Est. population 2020: 4,649,658 (21st smallest)
> Square miles: 397,954 (17th largest)
> Population growth 2015-2020: 2.8% (8th fastest)

A coastal country in western Africa, Mauritania is largely barren desert. As much of the country is uninhabitable, half of Mauritania’s population resides in the capital city of Nouakchott on the coast, with the other population centers lying along the southern border. Long periods of drought are causing the desert to expand, forcing many nomadic peoples and farmers into urban areas.
