In 2025, 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.

By 2030, the middle-class population in Asia-Pacific is expected to increase from **** billion people in 2015 to **** billion people. In comparison, the middle-class population of sub-Saharan Africa is expected to increase from *** million in 2015 to *** million in 2030. Worldwide wealth While the middle-class has been on the rise, there is still a huge disparity in global wealth and income. The United States had the highest number of individuals belonging to the top one percent of wealth holders, and the value of global wealth is only expected to increase over the coming years. Around ** percent of the world’s population had assets valued at less than 10,000 U.S. dollars, while less than *** percent had assets of more than one million U.S. dollars. Asia had the highest percentage of investable assets in the world in 2018, whereas Oceania had the highest percentage of non-investable assets. The middle-class The middle class is the group of people whose income falls in the middle of the scale. China accounted for over half of the global population for middle-class wealth in 2017. In the United States, the debate about the middle class “disappearing” has been a popular topic due to the increase in wealth among the top billionaires in the nation. Due to this, there have been arguments to increase taxes on the rich to help support the middle class.

Nigeria has the largest population in Africa. As of 2025, the country counted over 237.5 million individuals, whereas Ethiopia, which ranked second, has around 135.5 million inhabitants. Egypt registered the largest population in North Africa, reaching nearly 118.4 million people. In terms of inhabitants per square kilometer, Nigeria only ranked seventh, while Mauritius had the highest population density on the whole African continent in 2023. The fastest-growing world region Africa is the second most populous continent in the world, after Asia. Nevertheless, Africa records the highest growth rate worldwide, with figures rising by over two percent every year. In some countries, such as Chad, South Sudan, Somalia, and the Central African Republic, the population increase peaks at over 3.4 percent. With so many births, Africa is also the youngest continent in the world. However, this coincides with a low life expectancy. African cities on the rise The last decades have seen high urbanization rates in Asia, mainly in China and India. African cities are also growing at large rates. Indeed, the continent has three megacities and is expected to add four more by 2050. Furthermore, Africa's fastest-growing cities are forecast to be Bujumbura, in Burundi, and Zinder, Nigeria, by 2035.

As of February 2025, China ranked first among the countries with the most internet users worldwide. The world's most populated country had 1.11 billion internet users, more than triple the third-ranked United States, with just around 322 million internet users. Overall, all BRIC markets had over two billion internet users, accounting for four of the ten countries with more than 100 million internet users. Worldwide internet usage As of October 2024, there were more than five billion internet users worldwide. There are, however, stark differences in user distribution according to region. Eastern Asia is home to 1.34 billion internet users, while African and Middle Eastern regions had lower user figures. Moreover, the urban areas showed a higher percentage of internet access than rural areas. Internet use in China China ranks first in the list of countries with the most internet users. Due to its ongoing and fast-paced economic development and a cultural inclination towards technology, more than a billion of the estimated 1.4 billion population in China are online. As of the third quarter of 2023, around 87 percent of Chinese internet users stated using WeChat, the most popular social network in the country. On average, Chinese internet users spent five hours and 33 minutes online daily.

As of February 2025, the United States was the region with the largest TikTok audience by far, with almost ****** million users engaging with the popular social video platform. Indonesia followed, with around ***** million TikTok users. Brazil came in third, with almost ***** million users on TikTok watching short-videos. From Reels to Shorts: social short video takes the internet Between 2021 and 2022 some of the most popular social media platforms have been adding short-video features on the heels of TikTok’s popularity. YouTube Shorts, which rolled out to the global market in June 2021, reached *** billion monthly active logged-in users in 2023. In comparison, Instagram’s short-video format Reels, which launched in August 2020, presented a higher view rate than regular videos on the platform between June 2021 and June 2022, as well as a higher likes rate than other content types on Instagram. TikTok business model TikTok is owned by the Beijing-based ByteDance, along with the short-video app Douyin (TikTok’s version for the Chinese market), video platform Xigua, and popular news app Toutiao. While the products intended for domestic market consumption operate in the Chinese digital ecosystem and have a plurality of established monetization methods such as a live-shopping events hosted by famous influencers, TikTok’s main revenue stream comes from online advertising. In 2022, TikTok was estimated to have generated around **** billion U.S. dollars worldwide via online advertising.

As of February 2025, India was the country with the largest offline population worldwide. The South Asian country had over 651 million people without internet connection. China ranked second, with around 311.9 million people not connected to the internet. Despite these large shares of the disconnected population in these countries, China and India ranked first and second, respectively, as countries with the highest number of internet users worldwide. Internet access in Africa In 2023, Africa lagged behind other global regions regarding internet penetration rate, as only 37 percent of the continent’s population accessed the web. In contrast, around 91 percent of Europe’s population were internet users. This is heavily influenced by the infrastructure development in the region. However, some improvements are forecasted, as by 2028, the internet penetration rate in Africa will be at an estimated 48.15 percent. Global internet access challenges: disruptions and restrictions Government internet shutdowns around the world are another challenge for internet access. Between 2015 and the first half of 2023, 172 local internet connection disruptions occurred due to protests globally. Moreover, according to a 2023report on internet freedom, almost four out of ten global internet users were deprived of essential freedoms on online platforms. In 2023, 76 new restrictions on internet usage were implemented worldwide. Asia led in imposing these restrictions, accounting for approximately 55 cases across various countries in the region.

The statistic shows the number of unique mobile subscribers worldwide from 2010 to 2025. The number of global mobile connections is predicted to reach around **** billion by 2025.

Mobile connections - additional information

The first prototype of a handheld mobile phone was presented to the world in 1973, but it took more than ***** decades until mobile phones became accessible and affordable for almost everyone. In fact, figures show that there are about * billion mobile subscribers today worldwide, about *** thirds of the estimated global population. By 2020, the number of mobile subscriber is expected to increase to close to * billion, taking the global penetration rate to ** percent. Classic mobile phone use is on the decline however, with some ** percent of worldwide mobile phone users owning a smartphone as of 2015.

The world region with most mobile subscriptions is currently Asia Pacific, due to the area’s large population. As of 2016, Asia Pacific boasted over 4 billion cellular connections, ***** times more than both South and North America combined. In fact, no less than ***** Asian states (including transcontinental Russia) are present in a top 10 ranking of countries with the highest number of mobile- subscriptions. As of 2014, China is the largest market of mobile phone subscriptions in the world, home to some *** billion mobile-cellular users, the equivalent of about *** fifth of worldwide subscriptions. By 2019, this number is expected to increase to **** billion subscriptions.

Although the CIS (Commonwealth of Independent States), which includes some of the former member-states of the Soviet Union, ranks last in terms of number of mobile phone subscriptions, the region is first in terms of mobile phone penetration. As of 2016, there are an estimated ***** subscriptions per 100 inhabitants in the area, due to the fact that many users have multiple mobile phones at the same time.
