  • Leveraging High‐Frequency Digital Data to Analyze Forced Displacement Dynamics

    Open AccessEdith Darin, Ridhi Kashyap et al.ARTICLEPopulation and Development Review2026

    The quantification and analysis of forced displacement, driven by political unrest or natural disasters, has become increasingly central to both humanitarian and demographic research. With displaced populations reaching record numbers, there is an urgent need for accurate and timely data on displacement patterns, particularly disaggregated by age and gender. This paper introduces an analytical toolbox designed to leverage the growing diversity of…

  • How Accurate Are High Resolution Settlement Maps at Predicting Population Counts in Data Scarce Settings

    Open AccessEdith Darin, Ridhi Kashyap et al.ARTICLEPopulation Space and Place2025Referências: 1

    Despite the recent milestone of the world population surpassing 8 billion, disparities in population data reliability persist, with many countries facing outdated or incomplete census data. Such inaccuracies have far‐reaching implications for various sectors, including public health, urban planning, and resource allocation. The study leverages the rich data environment provided by the detailed 2018 Colombian census data and its coverage indicator…

  • Social cartography and satellite-derived building coverage for post-census population estimates in difficult-to-access regions of Colombia

    Open AccessLina Maria Sanchez-Cespedes, Douglas Ryan Leasure et al.ARTICLEPopulation Studies2024Referências: 27

    Effective government services rely on accurate population numbers to allocate resources. In Colombia and globally, census enumeration is challenging in remote regions and where armed conflict is occurring. During census preparations, the Colombian National Administrative Department of Statistics conducted social cartography workshops, where community representatives estimated numbers of dwellings and people throughout their regions. We repurposed…

  • Social capital mediates knowledge gaps in informing sexual and reproductive health behaviours across Africa

    Open AccessTill Koebe, Theophilus Aidoo et al.ARTICLESocial Science & Medicine2024Referências: 35

    Advancing sexual and reproductive health is essential for promoting human rights and women's empowerment, and combating the HIV/AIDS epidemic. A large body of literature across the social sciences emphasizes the importance of social capital, generated through the strength of social networks, for shaping health behaviours. However, large-scale measurement of social capital and social networks remains elusive, especially in the context of low-incom…

  • War and mobility

    Open AccessAthina Anastasiadou, Artem Volgin et al.ARTICLEDemographic Research2024Citada por: 4Referências: 9

    Background : Following the Russian invasion of Ukraine, many citizens left Russia due to increasing government repression, the fear of mobilization, or to escape the economic downturn. As yet, reliable statistical data on those who left are not available. Hence, much remains unknown about the characteristics and scope of this population. In the digital age, people prepare their journeys by searching online and these digital traces provide clues a…

  • Nowcasting Daily Population Displacement in Ukraine through Social Media Advertising Data

    Open AccessDouglas Ryan Leasure, Ridhi Kashyap et al.ARTICLEPopulation and Development Review2023Citada por: 15Referências: 28

    In times of crisis, real-time data mapping population displacements are invaluable for targeted humanitarian response. The Russian invasion of Ukraine on February 24, 2022, forcibly displaced millions of people from their homes including nearly 6 million refugees flowing across the border in just a few weeks, but information was scarce regarding displaced and vulnerable populations who remained inside Ukraine. We leveraged social media data from …

  • Classifying settlement types from multi-scale spatial patterns of building footprints

    Open AccessWarren C Jochem, Douglas Ryan Leasure et al.ARTICLEEnvironment and Planning B Urban…2021

    Urban settlements and urbanised populations continue to grow rapidly and much of this transition is occurring in less developed countries. Remote sensing techniques are now often applied to monitor urbanisation and changes in settlement patterns. In particular, increasing availability of very high resolution imagery (
