    Sub-national level dependency ratios: Africa 2010
    _________________________________________________________

    DATA DESCRIPTION: Gridded, spatial datasets for Africa providing version 1.0 estimates for dependency ratios at sub-national level. Ratios are based on sub-national estimates for 5-year age group proportions. The series is comprised of 3 raster datasets: 1) The ratio of dependents (both young, 0 to 14, and old, 65 ) upon the working age population; 2) The ratio of young dependents upon the working age population; 3) The ratio of older dependents upon the working age population.
    REGION: Africa
    DATA RESOLUTION: Sub-national administrative areas
    SPATIAL RESOLUTION: 0.00833333 decimal degrees (approx 1km at the equator)
    PROJECTION: Geographic, WGS84
    UNITS: Sub-national dependency ratios
    FORMAT: Geotiff (zipped using 7-zip (open access tool): www.7-zip.org)
    DATASET CONSTRUCTION DETAILS: This dataset is derived from the WorldPop Whole Continent Age Structures data series, described here:
    http://www.worldpop.org.uk/data/data_sources/. The Population count raster datasets for the relevant age groups were combined using spatial analytical tools in a GIS system, in order to derive the dependency ratios. Full details of WorldPop population mapping methodologies are described here: www.worldpop.org.uk/data/methods/
    DATE OF PRODUCTION: Dec 2016
