Este conjunto de datos contiene estimaciones de población, por edad y sexo, por celda de cuadrícula de 30 segundos de arco, coherentes con los censos nacionales y los registros de población. Hay una imagen para cada categoría de edad y sexo modelada según la ronda del censo de 2010.
La versión 4 de la población mundial en cuadrículas (GPWv4), revisión 11, modela la distribución de la población humana mundial para los años 2000, 2005, 2010, 2015 y 2020 en celdas de cuadrícula de 30 segundos de arco (aproximadamente 1 km). La población se distribuye a las celdas mediante la asignación proporcional de la población de las unidades administrativas y del censo. Los datos de entrada de la población se recopilan con la resolución espacial más detallada disponible a partir de los resultados de la ronda de censos de 2010, que se llevó a cabo entre 2005 y 2014. Los datos de entrada se extrapolan para producir estimaciones de población para cada año modelado.
