  • Comparing and integrating human mobility data sources for measles transmission modeling in Zambia

    Open AccessNatalya Kostandova, Christine Prosperi et al.ARTICLEPLOS Global Public Health2025

    Quantifying population mobility is crucial in developing accurate models of infectious disease dynamics. Increasingly, multiple data sources are available to describe individual and population mobility in a single location; however, there are no methods to systematically integrate these data. Combining information from these data sets may be valuable and help mitigate inherent biases in each data set due to sampling, censoring, and recall. We exa…

  • Comparing lagged impacts of mobility changes and environmental factors on Covid-19 waves in rural and urban India

    Open AccessEimear Cleary, Fatumah Atuhaire et al.ARTICLEPLOS Global Public Health2025

    Previous research in India has identified urbanisation, human mobility and population demographics as key variables associated with higher district level COVID-19 incidence. However, the spatiotemporal dynamics of mobility patterns in rural and urban areas in India, in conjunction with other drivers of COVID-19 transmission, have not been fully investigated. We explored travel networks within India during two pandemic waves using aggregated and a…

  • Disaggregating census data for population mapping using a Bayesian Additive Regression Tree model

    Open AccessOrtis Yankey, C Edson Utazi et al.ARTICLEApplied Geography2024

    Population data is crucial for policy decisions, but fine-scale population numbers are often lacking due to the challenge of sharing sensitive data. Different approaches, such as the use of the Random Forest (RF) model, have been used to disaggregate census data from higher administrative units to small area scales. A major limitation of the RF model is its inability to quantify the uncertainties associated with the predicted populations, which c…

    Open AccessQianwen Duan, Jessica Steele et al.ARTICLEHabitat International2024Referencias: 67

    Identifying the growing widespread phenomenon of counter-urbanisation, where people relocate from urban centres to rural areas, is essential for understanding the social and ecological consequences of the associated changes. However, its nuanced dynamics and complex characteristics pose challenges for quantitative analysis. Here, we used near real-time Facebook user count data for Belgium and Thailand, with missing data imputed, and applied the S…

  • 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 Studies2024Referencias: 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…

  • Combined and delayed impacts of epidemics and extreme weather on urban mobility recovery

    Open AccessHaiyan Liu, Jianghao Wang et al.ARTICLESustainable Cities and Society2023

    The ever-increasing pandemic and natural disasters might spatial-temporal overlap to trigger compound disasters that disrupt urban life, including human movements. In this study, we proposed a framework for data-driven analyses on mobility resilience to uncover the compound effects of COVID-19 and extreme weather events on mobility recovery across cities with varied socioeconomic contexts. The concept of suppression risk (SR) is introduced to qua…

  • Estimates of the number and distribution of zero-dose and under-immunised children across remote-rural, urban, and conflict-affected settings in low and middle-income countries

    Open AccessAdelle Wigley, Josh Lorin et al.ARTICLEPLOS Global Public Health2022

    While there has been great success in increasing the coverage of new childhood vaccines globally, expanding routine immunization to reliably reach all children and communities has proven more challenging in many low- and middle-income countries. Achieving this requires vaccination strategies and interventions that identify and target those unvaccinated, guided by the most current and detailed data regarding their size and spatial distribution. Th…

  • Assessing the characteristics of un- and under-vaccinated children in low- and middle-income countries

    Open AccessC Edson Utazi, Oliver Pannell et al.ARTICLEPLOS Global Public Health2022

    Achieving equity in vaccination coverage has been a critical priority within the global health community. Despite increased efforts recently, certain populations still have a high proportion of un- and under-vaccinated children in many low- and middle-income countries (LMICs). These populations are often assumed to reside in remote-rural areas, urban slums and conflict-affected areas. Here, we investigate the effects of these key community-level …
