The Geospatial Data & Analysis Center is lead by WorldPop at the University of Southampton, UK and is focused on geospatial data integration to improve the spatial demographic and health evidence base in low- and middle-income countries.
Over the past 15 years, WorldPop has developed open approaches to complement datasets from census and surveys with data from satellites, mobile phones and GPS to improve the spatial detail and timeliness of outputs. In the reproductive, maternal, newborn, child and adolescent health and nutrition (RMNCAH+N) field, WorldPop has developed approaches to estimate and map births, pregnancies and women of childbearing age, access to care, and the coverage of interventions and services.
The Geospatial Data & Analysis Centre will focus on three interlinked outcomes with corresponding activities.
- Increasing awareness of geospatial methods and datasets among partners by:
- Showcasing geospatial methods and mapping through meeting presentations and webinars.
- Building a repository of datasets relevant for monitoring subnational RMNCAH+N in the context of GFF investment cases.
- Developing guidelines and tools on geospatial methodologies relevant to monitoring that can be applied and adapted to country needs.
- Supporting Countdown country partnerships with geospatial analyses, as determined through discussions with Countdown partners. This may consist of in-country support through technical assistance and capacity strengthening, including contributing to national reports, face-to-face workshops or online training on subnational and gridded denominator estimation, mapping or both as requested.
- Research and development on new geospatial methods, insights and datasets to meet the call for district-level insights, together with the use of routine facility data. This will follow on and build from existing active WorldPop research and development.
Background Resources and Materials
This webinar presents an overview of available datasets and examples of how to use geospatial data to advance Countdown's agenda. Though not published as a Countdown to 2030 activity, this journal supplement published in BMJ Global Health in 2020 reviews use of geospatial data in reproductive, maternal, newborn, child, and adolescent health programs.
Some available geospatial datasets relevant to Countdown's activities include:
- Number of births, pregnancies, women of childbearing age, and age and sex groupings by 1x1 km area for all low and middle income countries.
- National and subnational level data on births, pregnancies, women of childbearing age (separate pages for national and subnational data.)
- Sub-national estimates of geographical accessibility of hospitals for women of childbearing age and the total population, for 43 countries in Sub-Saharan Africa in 2020. These data are also available as an interactive map.
Tools & Resources
The WorldPop Demographics tool allows the visualization of population structure in any given country.
The WorldPop Data Portal allows users to query and download rasters produced by the WorldPop research group. The tool allows the delineation of areas to query, returning zonal statistics. The size of the query area is limited to 100,000km2. Should you wish to download national-level data, please visit the WorldPop data repository
