Approximately 7.9 billion people live on Earth today, and CNN reported that 37% are in China and India. China is currently the most populated country, with 1.4 billion people, followed by India with 1.3 billion. Unsurprisingly, both countries also have some of the world’s most densely populated cities.

Several factors affect the number of people living in a city or country, such as politics, economy, and life quality. World Atlas reports that a town with a large number of available jobs will increase its population, while severe political and economic crises will often push people away. According to the United Nations University, climate change also became a reason for migration, and this phenomenon is expected to increase in the coming years.

Populated cities might offer more job opportunities, but it doesn’t always mean an enhanced quality of life as they also have to deal with many challenges. According to the United Nations, cities are responsible for producing the largest greenhouse gas emissions globally (60%) and consume nearly 80% of the energy produced.

For many years, Manila, the capital of the Philippines, held the title of the most densely populated city on Earth. However, the title now belongs to a city in Bangladesh.
