Countries with the largest population 2025

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.

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 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

Most viewed YouTube videos of all time 2025

On June 17, 2016, Korean education brand Pinkfong released their video "Baby Shark Dance", and the rest is history. In January 2021, Baby Shark Dance became the first YouTube video to surpass 10 billion views, after snatching the crown of most-viewed YouTube video of all time from the former record holder "Despacito" one year before. "Baby Shark Dance" currently has over 15 billion lifetime views on YouTube. 

“Baby Shark Dance” might be the current record-holder in terms of total views, but Korean artist Psy’s “Gangnam Style” video remained on the top spot for longest (1,689 days or 4.6 years) before ceding its spot to its successor. With figures like these, it comes as little surprise that the majority of the most popular videos on YouTube are music videos. Since 2010, all but one the most-viewed videos on YouTube have been music videos, signifying the platform’s shift in focus from funny, viral videos to professionally produced content. As of 2022, about 40 percent of the U.S. digital music audience uses YouTube Music.

Music fans are also highly engaged audiences and it is not uncommon for music videos to garner significant amounts of traffic within the first 24 hours of release. Other popular types of videos that generate lots of views after their first release are movie trailers, especially superhero movies related to the MCU (Marvel Cinematic Universe). The first official trailer for the upcoming film “Avengers: Endgame” generated 289 million views within the first 24 hours of release, while the movie trailer for Spider-Man: No Way Home generated over 355 views on the first day from release, making it the most viral movie trailer.

As of 2024, JavaScript and HTML/CSS were the most commonly used programming languages among software developers around the world, with more than 62 percent of respondents stating that they used JavaScript and just around 53 percent using HTML/CSS. Python, SQL, and TypeScript rounded out the top five most widely used programming languages around the world. 

At a very basic level, programming languages serve as sets of instructions that direct computers on how to behave and carry out tasks. Thanks to the increased prevalence of, and reliance on, computers and electronic devices in today’s society, these languages play a crucial role in the everyday lives of people around the world. An increasing number of people are interested in furthering their understanding of these tools through courses and bootcamps, while current developers are constantly seeking new languages and resources to learn to add to their skills. Furthermore, programming knowledge is becoming an important skill to possess within various industries throughout the business world. Job seekers with skills in Python, R, and SQL will find their knowledge to be among the most highly desirable data science skills and likely assist in their search for employment.

U.S. public debt 1990-2023

In September 2023, the national debt of the United States had risen up to 33.17 trillion U.S. dollars. The national debt per capita had risen to 85,552 U.S. dollars in 2021. As represented by the statistic above, the public debt of the United States has been continuously rising.

U.S. public debt Public debt, also known as national and governmental debt, is the debt owed by a nations’ central government. In the case of the U.S., national debt is owed by the federal government to Treasury security holders. Generally speaking, government debt increases with government spending, and can be decreased through taxes. During the COVID-19 pandemic, the U.S. government increased spending significantly to finance virus infrastructure, aid, and various forms of economic relief.

International public debt Venezuela leads the global ranking of the 20 countries with the highest public debt in 2021. In relation to the Gross Domestic Product (GDP), Venezuela's public debt amounted to around 306.95 percent of GDP. Eritrea was ranked fifth, with an estimated debt of 170 percent of the Gross Domestic Product.

The national debt of the United Kingdom is forecasted to grow from 87 percent in 2022 to 70 percent in 2027, in relation to the Gross Domestic Product. These figures include England, Wales, Scotland as well as Northern Ireland.

Greece had the highest national debt among EU countries as of the 4th quarter of 2020 in relation to the Gross Domestic Product. Germany ranked 13th in the EU, with its national debt amounting to 69 percent of GDP in the same time period.

Tuvalu was one of the 20 countries with the lowest national debt in 2021 in relation to the GDP, while Macao had an estimated level of national debt of zero percent, the lowest of any country. The data refer to the debts of the entire state, including the central government, the provinces, municipalities, local authorities and social insurance.

Sex ratio in China 1953-2024

In 2024, the sex ratio of the total population in China ranged at approximately 104.3 males to 100 females. Like most other sexual species, the sex ratio in humans tends to be one to one. But due to factors like sex selective abortions and different life expectancy between men and women, the sex ratio varies in different age groups.

China belongs to the countries with a very imbalanced sex ratio at birth. In 2023, the sex ratio in the population aging from 0 to 4 years old ranged at around 109 males to 100 females. The high gender inequality can be attributed to the traditional preference for male children in the Chinese society. Although gender identification before birth is not legally allowed in China, selective abortions due to gender preference still exist in many regions of China.

Gender imbalance can lead to many social problems, like the difficulty of finding a partner. Additionally, a country might also get economic benefits from its gender equality. According to the Global Gender Gap Report which was conducted by the World Economic Forum in 2017, there could be a 2.5 trillion U.S. dollar increase in China’s GDP if the gender gap could be closed. As China’s one-child-policy was officially ended in 2015, the problem of selective abortion due to gender preference is also expected to be alleviated.

GDP share of cities in India 2024

As of 2024, Mumbai had a gross domestic product of 368 billion U.S. dollars, the highest among other major cities in India. It was followed by Delhi with a GDP of around 167 billion U.S. dollars. India’s megacities also boast the highest GDP among other cities in the country.

Mumbai is the financial capital of the country, and its GDP growth is primarily fueled by the financial services sector, port-based trade, and the Hindi film industry or Bollywood. Delhi in addition to being the political hub hosts a significant services sector. The satellite cities of Noida and Gurugram amplify the city's economic status. The southern cities of Bengaluru and Chennai have emerged as IT and manufacturing hubs respectively. Hyderabad is a significant player in the pharma and IT industries. Lastly, the western city of Ahmedabad, in addition to its strategic location and ports, is powered by the textile, chemicals, and machinery sectors.

Cities propelling economic growth and generating a major share of GDP is a global phenomenon, as in the case of Tokyo, Shanghai, New York, and others. However, the GDP, which measures the market value of all final goods and services produced in a region, does not always translate to a rise in quality of life. Five of India’s megacities featured in the Global Livability Index, with low ranks among global peers. The Index was based on indicators such as healthcare, political stability, environment and culture, infrastructure, and others.

Number of Hajj pilgrims Saudi Arabia 1999-2025

The Hajj to Mecca in Saudi Arabia is considered among the world’s largest human gatherings, with over 1.67 million pilgrims in 2025. The Saudi government restricted Hajj to residents in Saudi Arabia only during the COVID-19 pandemic in 2020. The number of Hajj pilgrims dropped to about 58.7 thousand in 2021. Like other religious pilgrimages, Hajj is considered an annual rite of passage to renew one's moral and spiritual connection. Approximately a quarter of the human population identify themselves as Muslims. According to their faith of Islam, it is one of their five religious duties to perform the Hajj at least once in their lifetime.

According to Islamic tradition, any Muslim who has reached maturity is due to perform the Hajj. During the last Hajj season before the COVID-19 pandemic, about two thirds of the pilgrims to Mecca came from outside of the Saudi Arabian Kingdom. The government of Saudi Arabia issues each years’ Hajj visas on a country quota system, based on the size of the Muslim population .    

  One main condition for a mature Muslim to qualify to perform the Hajj is to be free of debt and other financial and social obligations. Many Muslims around the world spend a significant amount of their life-savings to be able to make this spiritual journey. As an example, the cost of performing Hajj for a Malaysian Muslim was calculated at about 22.45 thousand Malaysian ringgits. For first time Hajj pilgrims, the Malaysian government subsidizes more than half of that amount.

Some Muslims who can’t afford the financial or physical challenges of the Hajj sometimes perform the smaller Islamic pilgrimage to Mecca called Umrah, which can be attempted all year round.
