Instead, the most considerable jump in population is predicted for Africa, set to grow by almost 200% from almost 1.5 billion people today to 4.3 billion in 2100. However, the projections show that Asia will not be the biggest contributor to this growth. This would increase global population density from 59.11 people per square kilometer in 2022 to 80.82 per square kilometer in 2100. Looking ahead to 2100, the UN projects that the global population will rise to almost 11 billion. The Future of Population Density Near the Equator For a size comparison, Bangladesh is 1.55% the size of China, and Bahrain is only 0.01%. Out of the top 10 most densely populated countries in the world, only a couple can be found on the 25th and 26th parallel north⁠-Bangladesh and Bahrain.

Since density measures the ratio of people to physical space, countries with vast but sparse regions like China and India are less dense than imagined. Around 279 million people reside in these latitude lines, which run through large countries like India, Pakistan, Bangladesh, China, the United States, Mexico, and others.ĭespite their large landmasses, many of these countries do not themselves have very high population densities. In particular, the 25th and 26th parallel north are the most densely populated latitude circles.

Breaking down the population by latitude, we see the population becomes more concentrated near the equator.
