How does WorldPop’s modelling differ from Meta’s population datasets?
WorldPop’s population datasets are produced by integrating census, survey, and other local population data with a range of geospatial covariates through statistically validated population modelling approaches. In contrast, Meta’s population datasets are derived primarily from building footprint data combined with machine-learning methods and related spatial datasets. Where available, WorldPop often works with national statistical offices and local partners to incorporate recent country-specific data, particularly through its bespoke bottom-up modelling approaches, providing population estimates that are tailored to national contexts.
