Updating Global Urbanization Projections Under the Shared Socioeconomic Pathways

We updated the global urbanization level from 2015 to 2100 under the SSPs. We provide two projections generated from two data sources (i.e., World Urbanization Prospects (WUP, the 2018 revision) and World Bank (WB)) with time steps of 5 years and 1 year, respectively. The updated dataset of urbanization level has a potential to be widely applied to the study of future socioeconomic development and climate change. The data projected based on the WUP (2018 revision) database are stored under the 'WUP2018' folder, and the data predicted based on the WB database are stored under the 'WB' folder. The urbanization level and uncertainty for each country and area are stored in ‘.xls’ files named starting with different 'SSPs', and the files ending with ‘SD’ represent the standard deviation of the projections. In 'WUP2018' folder and 'WB' folder, we also provided files named ‘the 100% urbanization level countries and areas’ contains countries and areas in which urbanization levels were 100% in 2010 or 2009 and assumed their urbanization levels will stay in 100% in the future.
