Italy: High Resolution Population Density Maps + Demographic Estimates

To create our high-resolution maps, we use machine learning techniques to identify buildings from commercially available satellite images. Then we work with our partners at Columbia University to overlay general population estimates based on publicly available census data and other population statistics. The resulting maps are the most detailed and actionable tools available for aid and research organizations. For more information about the methodology used to create our high resolution population density maps and the demographic distributions, please visit: https://dataforgood.fb.com/docs/methodology-high-resolution-population-density-maps-demographic-estimates/

Adjustments to match the census population with the UN estimates are applied at the national level. The UN estimate for a given country (or state/territory) is divided by the total census estimate of population for the given country. The resulting adjustment factor is multiplied by each administrative unit census value for the target year. This preserves the relative population totals across administrative units while matching the UN total.
