🚨 New WorldPop gridded age & sex-structured population estimates for #Uganda in 2022 + methodology available to download: wopr.worldpop.org/?UGA/Population/v2.0

The outputs were co-developed with #UNICEF Columbia University and #GRID3 Top-down disaggregation (www.worldpop.org/methods/populations/) of U.S. Census Bureau projections to 100x100m grid cells was undertaken.

The Population Seen from Space: When Satellite Images Come to the Rescue of the Census

Le dénombrement de la population, dénominateur de nombreux indicateurs statistiques, est crucial pour les politiques publiques d’un pays. Il est du ressort des instituts nationaux de statistique d’en organiser la collecte, le plus souvent par le biais d’un recensement. Que se passe-t-il lorsqu’une partie du territoire n’est pas accessible aux agents recenseurs ? Actuellement, les données spatiales, telles qu’extraites de l’imagerie satellite, offrent une information géographique complète et de haute résolution, qui représente, lorsque combinée à un dénombrement partiel de la population, une opportunité sans précédent pour estimer les effectifs des territoires manquants. Leur précision spatiale rend également possible une estimation carroyée de la population en haute résolution, un format de données innovant à la croisée de la géographie et de la démographie. À partir du cas du Burkina Faso, cet article analyse comment le découpage du pays en carreaux de 100m sur 100m permet dans un premier temps de développer un modèle pour estimer, par le biais d’une approche hiérarchique bayésienne, la population des zones caractérisées par des problèmes sécuritaires n’ayant pas pu être dénombrées lors du dernier recensement de 2019. Ce découpage permet dans un second temps de désagréger les effectifs obtenus, par le biais d’un modèle d’apprentissage statistique pour obtenir une précision spatiale d’estimation de la population inégalée.

A virtual preEA workshop for the Republic of Guinea and Benin - WorldPop

Earlier this week Senior Research Fellow, Dr Sarchil Qader led an intensive 2-day bi-lingual virtual training workshop to strengthen Benin’s and the Republic of Guinea’s geospatial skills as they prepare to conduct national censuses.

Senior Enterprise Fellow Heather Chamberlain and Research Fellow Dr Assane Gadiaga have just returned from 4 days last week spent in Nairobi, Kenya learning from colleagues at #DHIS2, #HISP #Uganda HISP #Rwanda, Ministry of Health Uganda, #UNICEF and #GRID3 . They discussed sources of #population data, gridded population estimates and utility in the DHIS2 maps app - a really fruitful week working on Phase 2 of our GRID3 https://www.worldpop.org/current-projects/grid3-phase2
