A dataset detailing the top 10 countries with the lowest population density, including their respective population densities and contributing geographical factors.

In 2023, Washington, D.C. had the highest population density in the United States, with 11,130.69 people per square mile. As a whole, there were about 94.83 residents per square mile in the U.S., and Alaska was the state with the lowest population density, with 1.29 residents per square mile. The problem of population density Simply put, population density is the population of a country divided by the area of the country. While this can be an interesting measure of how many people live in a country and how large the country is, it does not account for the degree of urbanization, or the share of people who live in urban centers. For example, Russia is the largest country in the world and has a comparatively low population, so its population density is very low. However, much of the country is uninhabited, so cities in Russia are much more densely populated than the rest of the country. Urbanization in the United States While the United States is not very densely populated compared to other countries, its population density has increased significantly over the past few decades. The degree of urbanization has also increased, and well over half of the population lives in urban centers.

As of 2023, Guatemala was the most populated country in Central America with over 17.5 million inhabitants. Honduras followed in second with over 10 million. In contrast, Belize was the least populated with less than half a million inhabitants.

As of 2024, Barbados was the most densely populated country in Latin America and the Caribbean, with approximately 652 people per square kilometer. In that same year, Argentina's population density was estimated at approximately 16.7 people per square kilometer.

• The current US Census Bureau world population estimate in June 2019 shows that the current global population is 7,577,130,400 people on Earth, which far exceeds the world population of 7.2 billion in 2015. Our estimate based on UN data shows the world's population surpassing 7.7 billion.
• China is the most populous country in the world with a population exceeding 1.4 billion. It is one of just two countries with a population of more than 1 billion, with India being the second. As of 2018, India has a population of over 1.355 billion people, and its population growth is expected to continue through at least 2050. By the year 2030, India is expected to become the most populous country in the world. This is because India’s population will grow, while China is projected to see a loss in population.
• The following 11 countries that are the most populous in the world each have populations exceeding 100 million. These include the United States, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia, Mexico, Japan, Ethiopia, and the Philippines. Of these nations, all are expected to continue to grow except Russia and Japan, which will see their populations drop by 2030 before falling again significantly by 2050.
• Many other nations have populations of at least one million, while there are also countries that have just thousands. The smallest population in the world can be found in Vatican City, where only 801 people reside.
• In 2018, the world’s population growth rate was 1.12%. Every five years since the 1970s, the population growth rate has continued to fall. The world’s population is expected to continue to grow larger but at a much slower pace. By 2030, the population will exceed 8 billion. In 2040, this number will grow to more than 9 billion. In 2055, the number will rise to over 10 billion, and another billion people won’t be added until near the end of the century. The current annual population growth estimates from the United Nations are in the millions - estimating that over 80 million new lives are added yearly.
• This population growth will be significantly impacted by nine specific countries which are situated to contribute to the population growth more quickly than other nations. These nations include the Democratic Republic of the Congo, Ethiopia, India, Indonesia, Nigeria, Pakistan, Uganda, the United Republic of Tanzania, and the United States of America. Particularly of interest, India is on track to overtake China's position as the most populous country by 2030. Additionally, multiple nations within Africa are expected to double their populations before fertility rates begin to slow entirely.

In 2022, India overtook China as the world's most populous country and now has almost 1.46 billion people. China now has the second-largest population in the world, still with just over 1.4 billion inhabitants, however, its population went into decline in 2023. Global population As of 2025, the world's population stands at almost 8.2 billion people and is expected to reach around 10.3 billion people in the 2080s, when it will then go into decline. Due to improved healthcare, sanitation, and general living conditions, the global population continues to increase; mortality rates (particularly among infants and children) are decreasing and the median age of the world population has steadily increased for decades. As for the average life expectancy in industrial and developing countries, the gap has narrowed significantly since the mid-20th century. Asia is the most populous continent on Earth; 11 of the 20 largest countries are located there. It leads the ranking of the global population by continent by far, reporting four times as many inhabitants as Africa. The Demographic Transition The population explosion over the past two centuries is part of a phenomenon known as the demographic transition. Simply put, this transition results from a drastic reduction in mortality, which then leads to a reduction in fertility, and increase in life expectancy; this interim period where death rates are low and birth rates are high is where this population explosion occurs, and population growth can remain high as the population ages. In today's most-developed countries, the transition generally began with industrialization in the 1800s, and growth has now stabilized as birth and mortality rates have re-balanced. Across less-developed countries, the stage of this transition varies; for example, China is at a later stage than India, which accounts for the change in which country is more populous - understanding the demographic transition can help understand the reason why China's population is now going into decline. The least-developed region is Sub-Saharan Africa, where fertility rates remain close to pre-industrial levels in some countries. As these countries transition, they will undergo significant rates of population growth

Monaco led the ranking for countries with the highest population density in 2024, with nearly 26,000 residents per square kilometer. The Special Administrative Region of Macao came in second, followed by Singapore. The world’s second smallest country Monaco is the world’s second-smallest country, with an area of about two square kilometers and a population of only around 40,000. It is a constitutional monarchy located by the Mediterranean Sea, and while Monaco is not part of the European Union, it does participate in some EU policies. The country is perhaps most famous for the Monte Carlo casino and for hosting the Monaco Grand Prix, the world's most prestigious Formula One race. The global population Globally, the population density per square kilometer is about 60 inhabitants, and Asia is the most densely populated region in the world. The global population is increasing rapidly, so population density is only expected to increase. In 1950, for example, the global population stood at about 2.54 billion people, and it reached over eight billion during 2023.

In 2023, it was estimated that approximately 664 million people lived in Latin America and the Caribbean. Brazil is the most populated country in the region, with an estimated 216.4 million inhabitants in that year, followed by Mexico with more than 128.5 million.

This graph shows the population density of the United States of America from 1790 to 2019. In 2019, the population density was approximately 92.9 residents per square mile of land area. Population density in the United States Population density has been tracked for over two hundred years in the United States. Over the last two centuries, the number of people living in the United States per square mile has grown from 4.5 in 1790 to 87.4 in 2010. After examining the data in detail, it becomes clear that a major population increase started around 1870. Population density was roughly 11 at the time and has doubled in the last century. Since then, population density grew by about 16 percent each decade. Population density doubled in 1900, and grew in total by around 800 percent until 2010.

The population density of the United States varies from state to state. The most densely populated state is New Jersey, with 1,208 people per square mile living there. Rhode Island is the second most densely populated state, with slightly over 1,000 inhabitants per square mile. A number of New England states follow at the top of the ranking, making the northeastern region of the United States the most densely populated region of the country.

The least populated U.S. state is the vast territory of Alaska. Only 1.3 inhabitants per square mile reside in the largest state of the U.S.

Compared to other countries around the world, the United States does not rank within the top 50, in terms of population density. Most of the leading countries and territories are city states. However, the U.S. is one of the most populous countries in the world, with a total population of over 327 million inhabitants, as of 2018.

The autonomous Community of Madrid was Spain’s third most populous region. In 2024, of the approximately seven million people residing in the Community of Madrid, the largest age group comprised individuals aged 45–49 years, totaling up to over 610,000 inhabitants. In contrast, the smallest age group was that of people aged over 90 years old, which amounted to only about 91,000 inhabitants in Madrid in that year. Spain’s fertility rate, the lowest in Europe Spain has one of the lowest fertility rates in the European Union, with barely 1.29 children per woman, according to the latest reports. During the last ten years, the country featured a continuous population density of approximately 93–95 inhabitants per square kilometer – a figure far from the European average, which stood nearly at 112 inhabitants per square kilometer in 2021. Population in Madrid The population in the Community of Madrid soared between the 1990s and 2010, growing from 5 to nearly 6.5 million inhabitants in about 15 years, as it became an attractive destination for both national and foreign immigrants. Nevertheless, the Spanish financial crisis led many foreigners to move out of the region, and the number of foreign nationals fell from over one million in 2009 to approximately 698,100 in 2017. By 2024, this figure had recovered and was over the numbers registered before the crisis. As of 2022, the most common foreign nationalities in the Community of Madrid were Romanian, Moroccan and Venezuelan. Together, inhabitants from these countries totaled roughly 289,773.

This statistic depicts the countries with the lowest physicians density average worldwide for the period 2007-2016. As of that year, Niger was one of the countries with the lowest number of physicians per inhabitants. The African country was reported to have 0.0 physicians per 1,000 inhabitants.

In 202, according to the estimation, the Brazilian state of São Paulo was home to nearly 46 million people, making it the most populous state in the South American country. With less than half of São Paulo's population, Minas Gerais was the second most populous state in Brazil at that time. These two states are located in the South-East region of the country. Along with Rio de Janeiro and Espírito Santo, these states constitute Brazil's most populated region.

The United States had, by far, the highest homicide rate of the G7 countries between 2000 and 2023. In 2023, it reached 5.76 homicides per 100,000 inhabitants, a decrease from 6.78 in 2021. By comparison, Canada, the G7 nation with the second-highest homicide rate, had 1.98 homicides per 100,000 inhabitants in 2023. Out of each G7 nation, Japan had the lowest rate with 0.23 homicides per 100,000 inhabitants.

This statistic depicts the countries with the lowest density of hospital beds worldwide as of 2012. As of that year, Mali had only one bed per 10,000 inhabitants, and therefore was the country with the lowest density of hospital beds worldwide.

The United States had the largest population of the G7 countries between 2000 and 2023, increasing from 282 million to 335 million. It is also the country with the third highest number of inhabitants in the world. Interestingly, Japan's population has been in decline since 2010, falling from 128 million to 124.5 million. Also Italy's population has been decreasing in recent years. Aging population Both Italy, Germany, and Japan are characterized by an increasingly aging population. In 2023, Japan had the third highest median age worldwide, while Italy and Germany had the fourth and eighth highest, respectively. Despite Germany's high median age and aging population, the number of inhabitants continue to increase because of migration. Falling fertility rates Another reason for the declining populations in Japan and Italy are falling fertility rates. Both countries were among the 20 with the lowest fertility rates in the world in 2024, meaning that women in child-bearing age have fewer children.

In the Nordic countries, Sweden has the largest population with over ten million inhabitants in 2023. Denmark, Finland, and Norway all have between 5.5 and six million inhabitants, whereas Iceland clearly has the lowest number with only 390,000 people. The population increased in all five Nordic countries over the past 20 years. Aging population In all five Nordic countries, the average age of the population is increasing. In all countries except Iceland, people aged 70 years or more make up the largest age groups. Hence, one of the issues facing the Nordic countries in the coming decades is that of a shrinking working stock, while there will be more elderly people in need of daily care. Births, deaths, and migration The two reasons behind the constantly increasing population in the Nordic countries are that more people are born than people dying, and a positive net migration. Except for Finland, the death rate decreased in all Nordic countries over the past 20 years. However, the fertility rate has also fallen in all five countries in the recent years, meaning that an increasing immigration play an important role in sustaining the population growth.
