In 2023, the district of the Shanghai municipality with the highest resident population density was Hongkou district with an average of ****** people living on one square kilometer. The average density of the population of the Shanghai municipality in total was ***** people per square kilometer that year.

In 2023, the average resident population density in the Shanghai municipality was ***** people per square kilometer. This figure remained largely unchanged in the recent five years.

China is a vast and diverse country and population density in different regions varies greatly. In 2024, the estimated population density of the administrative area of Shanghai municipality reached about 3,911 inhabitants per square kilometer, whereas statistically only around three people were living on one square kilometer in Tibet. Population distribution in China China's population is unevenly distributed across the country: while most people are living in the southeastern half of the country, the northwestern half – which includes the provinces and autonomous regions of Tibet, Xinjiang, Qinghai, Gansu, and Inner Mongolia – is only sparsely populated. Even the inhabitants of a single province might be unequally distributed within its borders. This is significantly influenced by the geography of each region, and is especially the case in the Guangdong, Fujian, or Sichuan provinces due to their mountain ranges. The Chinese provinces with the largest absolute population size are Guangdong in the south, Shandong in the east and Henan in Central China. Urbanization and city population Urbanization is one of the main factors which have been reshaping China over the last four decades. However, when comparing the size of cities and urban population density, one has to bear in mind that data often refers to the administrative area of cities or urban units, which might be much larger than the contiguous built-up area of that city. The administrative area of Beijing municipality, for example, includes large rural districts, where only around 200 inhabitants are living per square kilometer on average, while roughly 20,000 residents per square kilometer are living in the two central city districts. This is the main reason for the huge difference in population density between the four Chinese municipalities Beijing, Tianjin, Shanghai, and Chongqing shown in many population statistics.

According to official figures, around 24.8 million permanent residents were living in the administrative area of Shanghai municipality in 2024. This was 71,900 people less than in the previous year. Population development in Shanghai During the economic reform and opening-up period, Shanghai’s population more than doubled and reached 24.5 million in 2013. However, the limits of demographic growth in Chinese megacities became increasingly apparent since the beginning of the 21st century. In 2017, the Shanghai municipal government planned to limit Shanghai's population and to keep the population within the 25 million-threshold until 2035. As a result, the total population has remained relatively stable since 2013. Furthermore, inhabitants are unevenly distributed across the city districts, with the central urban areas having population densities of around 20,000 people or more per square kilometer. Current demographic shifts Under the conditions of restricted demographic inflows, the effect of population aging becomes increasingly apparent in Shanghai. The city traditionally had a low birth rate compared to other regions in China. In recent years, the number of deaths exceeded the number of births, a development that most probably started in 2020. This development is also reflected in the share of people aged 65 and over which increased steadily in recent times. If migration barriers are not lowered, population decrease in Shanghai is likely in the future.

In 2024, about 943.5 million people lived in urban regions in China and 464.8 million in rural. That year, the country had a total population of approximately 1.41 billion people. As of 2024, China was the second most populous country in the world. Urbanization in China Urbanization refers to the process by which people move from rural to urban areas and how a society adapts to the population shift. It is usually seen as a driving force in economic growth, accompanied by industrialization, modernization and the spread of education. Urbanization levels tend to be higher in industrial countries, whereas the degree of urbanization in developing countries remains relatively low. According to World Bank, a mere 19.4 percent of the Chinese population had been living in urban areas in 1980. Since then, China’s urban population has skyrocketed. By 2024, about 67 percent of the Chinese population lived in urban areas. Regional urbanization rates In the last decades, urbanization has progressed greatly in every region of China. Even in most of the more remote Chinese provinces, the urbanization rate surpassed 50 percent in recent years. However, the most urbanized areas are still to be found in the coastal eastern and southern regions of China. The population of Shanghai, the largest city in China and the world’s seventh largest city ranged at around 24 million people in 2023. China’s urban areas are characterized by a developing middle class. Per capita disposable income of Chinese urban households has more than doubled between 2010 and 2020. The emerging middle class is expected to become a significant driver for the continuing growth of the Chinese economy.

In 2023, the urbanization rate in different provinces of China varied between 89.5 percent in Shanghai municipality and 38.9 percent in Tibet. The national average urbanization rate reached around 66.2 percent in 2023. Urbanization and economic development During China’s rapid economic development, the share of people living in cities increased from only 19.4 percent in 1980 to nearly 64 percent in 2020. Urbanization rates are now coming closer to those in developed countries. However, the degree of urbanization still varies significantly between different regions in China. This correlates generally with the level of economic development across different regions in China. In eastern Chinese regions with high personal income levels and high per capita GDP, more inhabitants are living in cities than in the countryside. Influence of geography Another reason for different urbanization rates lies in the huge geographic differences of regions in China. Basically, those regions with a low population density often also display lower urbanization rates, because their inhabitants live more scattered across the land area. These differences will most probably remain despite further economic progress.

Recreational green spaces are associated with human thriving and well-being. During the COVID-19 pandemic a spotlight has been shed on the importance of these spaces such as recreational green in close proximity to the place of residence. In a novel approach, we apply a multiscale analysis using different density measurements, correlations between density and green space, as well as the influence of architectural form and spatial structures to understand the accessibility of recreational green on the micro-scale of a building block. For this purpose, we use geospatial-data analysis and in-depth neighborhood studies to compare two cities in Asia and Europe revealing different ways of organizing density in the built environment and identifying a derivation of approaches for sustainable development in dense urban regions. The geodatabase includes information on building footprints, derived settlement units and core urban areas for the Berlin-Brandenburg urban region and Qingdao urban region and population grid. Vegetation has been isolated from satellite images using NDVI for both study regions, neighborhood site borders, neighborhood site buildings, neighborhood site vegetation and calculated green densities. The research was done by SpACE Lab at ISU (TU Braunschweig) in collaboration with the College of Urban Planning (CAUP) at Tongji University Shanghai (China).
