High-resolution grids, created from historical census data, can help in the study of population changes and the combined analysis of population with other variables. We propose a hybrid disaggregation technique that combines dasymetric mapping and pycnophylactic interpolation, leveraging different types of ancillary variables in order to disaggregate historical census data into a 200 m grid. We report on experiments with data from three national censuses from around 1900, in Great Britain, Belgium, and the Netherlands. Our method outperforms simpler schemes based on mass-preserving areal weighting or pycnophylactic interpolation. The best results were obtained using modern regression methods (i.e., gradient tree boosting or convolutional neural networks, depending on the case study), which were previously only seldom used for spatial data disaggregation.
