摘要：Urbanization level is an important indicator of socioeconomic development, and projecting its dynamics is fundamental for studies related to global socioeconomic and climate change. this paper aims to update the projections of global urbanization from 2015 to 2100 under the Shared Socioeconomic Pathways by using the logistic ftting model and iteratively identifying reference countries . Based on historical urbanization level database from the World Urbanization Prospects, projected urbanization levels and uncertainties are provided for 204 countries and areas every fve years . The 2010–2100 year-by-year projected urbanization levels and uncertainties based on the annual historical data from the World Bank (WB) for 188 of countries and areas are also provided . The projections based on the two datasets were compared and the latter were validated using the historical values of the WB for the years 2010–2018 . The updated dataset of urbanization level is relevant for understanding future socioeconomic development, its implications for climate change and policy planning.
