Edith Darin presenting at IBGE workshop 2022

Working with Brazil’s National Statistics Office as they prepare for their biggest ever census

As Brazil prepares for its biggest ever census, WorldPop Research Fellow Edith Darin presented on bottom-up population modelling last month as part of a two-week workshop at the Instituto Brasileiro de Geografia e Estatística (IBGE, the Brazilian Statistics Office) in Rio de Janeiro. Edith’s contribution came at an important milestone for the IBGE. In August …

Exploring satellite datasets and advanced statistical models to estimate crop production in Iraq

Ensuring food security and shaping policy intervention require accurate and timely mapping and monitoring of agricultural dynamics and production. Many low- and middle-income countries do not have sufficient information on agricultural outputs to inform policy decisions and enable field monitoring – especially at the level of individual farms.  This lack of high spatial resolution data …

Finding where population health studies have been conducted to inform climate-health research

A new research project is setting out to unlock the potential of combining health monitoring data with climate datasets that cover the same times and regions to improve our understanding of the impact of climate on human health. With funding from the Wellcome Trust, this 12-month project brings together expertise from afrimapr (Liverpool School of Tropical Medicine), …

WorldPop, open data for spatial demography

High resolution, contemporary data on human population distributions, their characteristics and changes over time are a prerequisite for the accurate measurement of the impacts of population growth, for monitoring changes and for planning interventions. WorldPop aims to meet these needs through the provision of detailed and open access spatial demographic datasets built using transparent approaches.  …

Seasonal association between viral causes of hospitalised acute lower respiratory infections and meteorological factors in China: a retrospective study

Background Acute lower respiratory infections (ALRIs) caused by respiratory viruses are common and persistent infectious diseases worldwide and in China, which have pronounced seasonal patterns. Meteorological factors have important roles in the seasonality of some major viruses, especially respiratory syncytial virus (RSV) and influenza virus. Our aim was to identify the dominant meteorological factors and …

International population movements and regional Plasmodium falciparum malaria elimination strategies

Calls for the eradication of malaria require the development of global and regional strategies based on a strong and consistent evidence base. Evidence from the previous global malaria eradication program and more recent transborder control campaigns have shown the importance of accounting for human movement in introducing infections to areas targeted for elimination. Here, census-based …

Exploring the use of mobile phone data for national migration statistics

Exploring the use of mobile phone data for national migration statistics Statistics on internal migration are important for keeping estimates of subnational population numbers up-to-date, as well as urban planning, infrastructure development, and impact assessment, among other applications. However, migration flow statistics typically remain constrained by the logistics of infrequent censuses or surveys. The penetration …

Evaluating nighttime lights and population distribution as proxies for mapping anthropogenic CO2 emission in Vietnam, Cambodia and Laos

Tracking spatiotemporal changes in GHG emissions is key to successful implementation of the United Nations Framework Convention on Climate Change (UNFCCC). And while emission inventories often provide a robust tool to track emission trends at the country level, subnational emission estimates are often not reported or reports vary in robustness as the estimates are often …

Changing epidemiology and challenges of malaria in China towards elimination

Changing epidemiology and challenges of malaria in China towards elimination Background Historically, malaria had been a widespread disease in China. A national plan was launched in China in 2010, aiming to eliminate malaria by 2020. In 2017, no indigenous cases of malaria were detected in China for the first time. To provide evidence for precise …
