![]() ![]() In Italy, another phenomenon affects population density and urban development-a sprawling coastline.ĭespite having a large population of 59 million and large metropolitan areas throughout, Italy’s population spikes are closer to the water. That said, the relatively recent reunification of West and East Germany in 1991 meant that post-WWII growth was mostly concentrated in West Germany (and West Berlin). Berlin is the most populated at 3.5 million residents in the city proper, and 6 million in the wider urban area. Unlike France, Germany has many dense cities and regions, with Berlin, Munich, Stuttgart, and Cologne all having over a million residents. Many residents in the Paris metropolitan area are employed in the service sector, which makes up one-third of France’s $2.78 trillion gross domestic product. But a staggering one-fifth of the French population lives in Paris and its surrounding metro-the most populous urban area in Europe.

Let’s take a look at how the population spreads out in different countries around the world. France and Germany: Population Density Spikes and Troughs He used popular programming language R and a path-tracing package, Rayshader, to create the maps. This series of 3D maps from Terence Teo, an associate professor at Seton Hall University, renders the population density of six countries using open-source data from Kontur Population. But none of this growth has been evenly spread out, including within countries. In the last 100 years, the global population more than quadrupled. By 2050, the population is projected to grow to 10 billion. With the emergence of smart and green cities, the quality of life for many urban dwellers will likely continue to improve, and more large urban areas will morph into megacities.Īs of 2022, Earth has 8 billion humans. Convenience, better jobs, easier access to social services, and higher wages are among the many reasons people are likely to continue to move to cities, even in the post-COVID era. While there are certainly downsides to mass urbanization, like pollution and overcrowding, the upsides clearly outweigh the negatives for most people. Since 2012, deaths in the EU have actually been outpacing births-and in 2019, there were 4.7 million deaths compared to 4.2 million births, though net migration kept population numbers from falling. Urban growth will continue mainly in Asia and Africa, as some cities in regions such as Europe actually begin to shrink in population due to aging citizens and declining birth rates. In addition, Guangzhou, Shenzhen, and Chennai are all expected to meet the megacity definition by 2035. Specifically, it’s projected that Bangalore (India) and Lahore (Pakistan) will boot out Tianjin and Buenos Aires. Rankīy 2035, two new cities are expected to crack the top 20 list. Here’s a closer look at the top 20 most populous cities. In fact, it’s expected that Delhi’s population could surpass Tokyo’s by 2028. Indian and Chinese cities, on the other hand, will continue to grow rapidly in the coming years. While Tokyo is the world’s most populous city with 37,393,000 people, this number is leveling out due to declining birth rates and an aging population. Interestingly, Mexico City placed third on the top largest cities list in 2010, but has since experienced slower growth compared to its competitors, Shanghai and São Paulo. Meanwhile, São Paulo grew by more than 2 million, and Mexico City gained just over 1.6 million people. While Tokyo only gained 559,000 people between 20, Delhi gained over 8 million people in the same time frame. How much have the world’s five most populous cities grown in just the last decade? Rank Prospects of better job opportunities and higher wages, along with shifts from agrarian to industrial and service-based economies, are causing mass movement to cities. Rural-to-urban migration is an increasingly relevant trend in the 21st century. Today, more than 80% of people in higher income countries find themselves living in urban areas, and in upper-middle income countries the number lies between 50-80%. This visualization, using data from Macrotrends, shows the 20 most populous cities in the world. This means that the world’s top 20 most populous cities are all megacities. Megacities are defined as urban areas with a population of more than 10 million people. ![]() More than half of the world’s population currently lives in cities-and as time goes on, it’s clear that more urban dwellers will find themselves living in megacities.
