13 Bottom-Up Geostatistical Population Modelling

This section presents a model-based geostatistical approach for bottom-up population modeling, offering a detailed exposition of the theoretical and methodological frameworks underpinning this approach for population modelling. The section begins by establishing the methodological foundation, defining the key principles and statistical models that drive geostatistical analysis in the context of bottom-up population modelling. Further, this section provides a series of illustrative use case country examples to demonstrate the practical application and effectiveness of model-based geostatistical approaches for population modelling.
