The population size of China’s counties shows a clear trend of growth and regional differences. The average population size of Chinese counties grew from 228,000 to 498,000 during the period from the first to the seventh national census, with the largest average population growth from the seco...

Land use extraction It has been found that the heat stress effect is stronger in the core area of large cities with high population density11. Thus, within the QGIS Version 3.32.3 environment, the present study clips the shape file (Fig.S3) of the core urban area based on administrative d...
Social media bots have been observed to perform information maneuvers. Governments like those of Iran and China are using social media automation to disseminate propaganda and provide digital entertainment to their population [35]. Russian bots have been identified to pretend to be English speakers and...
(In other words, between now and then China is likely to lose a number of workers larger than the entire population of Brazil.) The under-14 population will also fall in that same period, from just over 250 million in 2020 toa median projection of 150 million in 2050. Not only will ...

role of garbage in the transmission chain is more indirect in the sense that garbage has a complex relationship with public toilets [15]. Hence, pushing the ratio of public toilets to the local population in a city to its optimal level would help to reduce the total infection in a region....
“Abundance estimation of large carnivores is essential for their effective conservation plan- ning, yet estimating population size is challenging due to their elusive and wide-ranging nature. China is estimated to encompass 60% of the snow leopard Panthera uncia habitat, making it a crucial pillar...
While the Sustainable Development Goal (SDG) index is a widely employed method of measuring progress in the United Nations (UN) SDGs, as it allows comparisons across countries and regions, it does not usually offer any indication as to how to move the SDGs forward. To address this deficit, ...
Stock-based material flow analysis approach, discrete choices method, Gompertz model etc. are used to project energy service demands for the subsectors according to given socioeconomic development scenarios. The socioeconomic driver settings such as the gross domestic product (GDP), population, urbaniza...
