![]() ![]() In the last thirty years, China has undergone the largest process of urbanisation in history. A classic example is the northeastern seaboard of the USA, a megalopolis as Gottman termed it, stretching hundreds of miles from Washington through New York City to Boston, with around 50m people. In the early 20th century, geographers observed how rail and road networks were allowing rapidly growing cities to fuse together into vast sprawling conurbations. This is the world's largest agricultural region, supporting a population of around 450 million people in India and 120 million in Bangladesh. This is particularly the case along the Ganges plain in northern India, stretching nearly 2000km from just east of Delhi to Dhaka in Bangladesh. If we zoom in on India (click on links to focus the map), we can see the complexity of rural, peri-urban and urban landscapes, with thousands and thousands of villages, towns and cities in an intricate hierarchy. While India has many of the world's largest cities, it retains a huge rural population of around 900 million people. Both countries have a population of 1.4 billion, with India set to move ahead of China and reach 1.5 billion by 2030. India: the World's Most Populous CountryĪt the global scale, the world population density map highlights the immense concentration of humanity in India and China. Some introductory highlights from the data are discussed below with links for further information. This website has received 500,000 visitors since 2020, illustrating the widespread interest in global population geography. The GHSL records the complexity and diversity of human settlement, beyond simple rural-urban divisions. Integrating huge volumes of satellite data with national census data, the GHSL describes in detail the settlement geography of the entire globe, and has applications for a wide range of research and policy related to urban growth, development and sustainability. ![]() The data is from the Global Human Settlement Layer (GHSL) 2023 produced by the European Commission JRC and the Center for International Earth Science Information Network at Columbia University. This interactive map shows population density in 2020, measured in residents per square kilometre. Urban and rural population in the U.S.Visualising Population Density Across the Globe Population density in California 1960-2018 Population density in New Jersey 1960-2018 metro areas with the highest concentration of high-income households 2011 Population density in Tennessee 1960-2017 The degree of urbanization has also increased, and well over half of the population lives in urban centers. While the United States is not very densely populated compared to other countries, its population density has increased significantly over the past few decades. However, much of the country is uninhabited, so cities in Russia are much more densely populated than the rest of the country. While this can be an interesting measure of how many people live in a country and how large the country is, it does not account for the degree of urbanization, or the share of people who live in urban centers.įor example, Russia is the largest country in the world and has a comparatively low population, so its population density is very low. Simply put, population density is the population of a country divided by the area of the country. As a whole, there were about 94 residents per square mile in the U.S., and Alaska was the state with the lowest population density, with 1.28 residents per square mile. had the highest population density in the United States, with 10,984.43 people per square mile. ![]()
