Global population growth is entering a new phase as the United Nations World Population Prospects projects that the world’s population will reach about 10.1 billion people by 2100, with almost all net growth coming from Africa, while Europe and parts of Asia decline.

Nigeria, Africa’s most populous nation, is now giving birth to more babies each year than all of Europe plus Russia combined, a milestone that reflects profound global demographic change.

In 1970, only about 310 million people flew each year. Today, that figure has exploded into the billions and by 2053, it may more than double again.

Across Europe, birth rates tell a changing story. According to new findings from the Pew Research Center, Muslim families are having more children on average than non-Muslims, a pattern that is reshaping the region’s population dynamics.

Across much of the world, people are having fewer children than ever before. A new visual from World Visualised, using World Bank data, shows a striking pattern: between 2000 and 2023, fertility rates in the ten largest countries have fallen sharply, and in five of them, they’ve dropped below the replacement level of 2.1 births per woman.

Latin America has long been associated with high crime rates, violent cartels, and drug trafficking networks that dominate global headlines. Countries like El Salvador, Colombia, and Mexico are often cited for their struggles with narco-violence, gang warfare, and soaring homicide rates.

The world’s demographic map is changing rapidly, and the shift is most visible in Africa. Several African countries are set to experience extraordinary population growth by 2050, while other regions of the world will expand more slowly or even begin to decline.

The world is undergoing an unprecedented urban transformation, with several cities now exceeding 15 million residents. Megacities such as Istanbul, Lagos, Guangzhou, Shenzhen, Beijing, Karachi, Delhi, and Shanghai are experiencing the most moves. The Cities in Numbers

Do you count your calories? Every individual has different needs, based on their height, weight, lifestyle and other factors. But whether they can fulfil those needs often depends on where they live.

World Visualized’s graphic charting the median age of the global population from 1950 to 2025 shows a steady rise: from around 22 years in 1950 to more than 30 years in 2025. The pattern highlights how advancements in healthcare and education, combined with declining fertility rates, are transforming societies worldwide.

There are notable imbalances between male and female populations across several countries in 2025.

India has officially become the most populous country on Earth, overtaking China with a 17.76% share of the global population, according to Worldometer. China follows closely at 17.72%, while the United States remains a distant third at 4.23%.

The world has slowly grown to pay attention to only two religions: Christianity and Islam. These two religions have 2.3 billion and 1.9 billion followers, respectively, globally.
