High-resolution population estimates
Demographic data is key to impactful operational work and sustainable planning. It provides a wide range of information on population including size, age, density and location. This data helps governments and society to best respond to populations’ needs and monitor population changes. In some countries, however, traditional population data sources can be outdated or incomplete, due to lack of infrastructure, capacity or financial resources. To provide countries with accurate and relevant high-resolution population data, GRID3 uses two complementary pathways: assistance in the generation and utilisation of high-resolution population and housing census data, and population modelling, which provides gridded population estimates. GRID3 uses two methods to produce gridded population data, depending on country needs: the bottom-up and top-down approaches.
