Income maps have been extensively used for identifying populations vulnerable to global changes. The frequency and intensity of extreme events are likely to increase in coming years as a result of climate change. In this context, several studies have hypothesized that the economic and social impact of extreme events depend on income. However, to rigorously test this hypothesis, fine‐scale spatial income data is needed, compatible with the analysis of extreme climatic events. To produce reliable high‐resolution income data, we have developed an innovative machine learning framework, that we applied to produce a European 1 km‐gridded data set of per capita …

In recent decades, detailed country-level estimates of income and wealth have become widely available and inform us about the evolution of inequality between and within countries. But a substantial portion of these available datasets lack sub-national geographical information, precluding the exploration of the spatial distribution and evolution of inequalities within countries. We present here a new dataset of disposable income for Europe at the subnational level. It has been compiled from existing income data (gross income, gross earnings, equivalised income, etc.) published by national statistical institutes at different geographical levels. We used linear regressions and numerical operations to estimate disposable …

Abstract Climate risk in Europe is unevenly distributed among the population and is projected to increase substantially over the 21st century due to evolving climatic and socioeconomic conditions. Projections of vulnerability drivers, such as income distribution, are needed for assessing future climate risk. In Europe, existing studies typically rely on inadequate proxies, such as gross domestic product per capita, to account for future vulnerability associated with income levels. This study presents a novel top–down iterative methodology to produce decadal, high-resolution (1 km) maps of disposable income across Europe for the 21st century consistent with the Shared Socioeconomic Pathways (SSPs).
