HANZE-Exposure is a model and dataset that aims at quantifying the evolution of key socioeconomic drivers in Europe since 1870, namely land use, population, economic activity and assets. It consists of algorithms to reallocate baseline (2011) land use and population for any given year based on a large collection of historical subnational- and national-level statistics, and then disaggregate data on production and tangible assets by economic sector into a high-resolution grid. Maps generated by the model enable reconstructing exposure within the footprint of any extreme event both at the time of the event and in any other moment in the past 150 years. The full algorithm and input data are publicly available. The input data include a dataset of primary socioeconomic data for 1870-2020 at NUTS3 or national level for 42 countries derived from almost 400 sources.
