Top 50 countries with largest population in 2050

Visualizing the Changing World Population, by Country

On average, there are 250 babies born every minute around the world. This adds up to over 130 million new human beings entering the world every year.

Then it’s no surprise that the world’s population, which now stands at a whopping 8 billion, has more than tripled since the mid-20th century.

This graphic by Truman Du uses December 2022 population data from the UN and summaries from the French Institute for Demographic Studies (INED) to show the unequal rise and fall of the world’s population by 2050.

Let’s take a closer look at some of these population trends.

Most Populous Countries: 2022 vs. 2050

The Asian countries of India and China have topped the rankings of the world’s most populous countries for hundreds of years.

China currently holds the number one spot on this list. But the population of India is expected to surpass that of China’s by later this year, eventually reaching a total of 1.67 billion in 2050.

RankMost Populous Countries (2022)Population (2022)Most Populous Countries (2050)Population (2050)
1China1.43BIndia1.67B
2India1.42BChina1.32B
3United States of America338MUnited States of America375M
4Indonesia276MNigeria375M
5Pakistan236MPakistan366M
6Nigeria219MIndonesia317M

The United States, Nigeria, Pakistan, and Indonesia are the next most populous countries in 2022, and they are expected to hold onto these spots until 2050. However, they have a long way to go before catching up with the top two, as their combined population doesn’t add up to half that of India and China’s total.

Interestingly, it is estimated that Nigeria’s population will shoot up to 375 million by 2050, almost matching the population of the United States. In 2022, the African country’s population was just around 219 million. This expected spike is largely due to a high birth rate and booming economy, and the resultant rural-to-urban migration.

Countries with Declining Populations

While many countries will be seeing their populations boom over the next three decades, other nations such as China are expected to experience the opposite.

CountryPopulation (2022)Population (2050F)
China1.425 billion1.316 billion
Japan123.9 million104.1 million
Russian Federation144.7 million133.4 million
Italy59.0 million52.4 million
Republic of Korea51.8 million45.9 million
Germany83.4 million79.1 million
Thailand71.7 million68.1 million
Spain 47.6 million44.3 million

Several countries in the world are expected to see their populations decline over the next 30 years. And the main reason for this: extremely low birth rates.

South Korea, which has the world’s lowest fertility rate, is expected to see a sharp decline of almost 12% in its population as it falls to 46 million by 2050.

Changing world population trends like this can pose challenges for economies around the world, such as labor shortages, aging populations, and an increasing financial burden on younger generations.

Terrorism remains a pressing issue globally, with the number of countries recording a terrorist incident increasing from 58 to 66 last year.

This map visualizes the locations and number of deaths of the 20 most deadly terrorist attacks in 2024.

The data comes from the Institute for Economics & Peace.

Defining Terrorism

The Institute for Economics & Peace follows the Global Terrorism Database’s definition of terrorism, which is “the threatened or actual use of illegal force and violence by a state and non-state actor to attain a political, economic, religious, or social goal through fear, coercion, or intimidation.”

The Global Terrorism Database’s definition also includes the following criteria:

  1. The violent act was aimed at attaining a political, economic, religious, or social goal;
  2. The violent act included evidence of an intention to coerce, intimidate, or convey some other message to a larger audience (or audiences) other than the immediate victims; and
  3. The violent act was outside the precepts of International Humanitarian Law.

Defining terrorism is a complex and contested issue, with governments and scholars often disagreeing on specific elements, such as whether victims must be non-combatants or if a political motive is required

The Sahel, a region stretching from Senegal to Eritrea across north-central Africa, is now the world’s most terrorism-affected area. Since 2019, terrorism-related deaths in the region have increased tenfold.

In 2024 alone, the Sahel was responsible for more than half of all terrorism-related fatalities worldwide. Burkina Faso remained the hardest-hit country, accounting for one in five terrorism deaths globally.

According to the Institute for Economics & Peace, this dramatic rise is driven by a mix of factors: political instability, weak governance, ethnic conflicts, porous borders, environmental degradation, the spread of transnational jihadist networks, and increasing geopolitical rivalry.

The four deadliest terrorist groups in 2024 were the Islamic State (IS), Jamaat Nusrat al-Islam wal-Muslimeen (JNIM), Tehrik-e-Taliban Pakistan (TTP), and al-Shabaab.

JNIM remains the most active group in Burkina Faso, responsible for nearly half of all attacks there last year. Its presence has grown significantly, with both the number of attacks and related deaths rising by over 50% compared to the previous year.
