Estimates of total number of people per grid square broken down by gender and age groupings (including 0-1 and by 5-year up to 80+) in 2020 for Armenia.
The dataset is available to download in Geotiff format at a resolution of 3 arc seconds (approximately 100m at the equator). The projection is Geographic Coordinate System, WGS84. The units are estimated number of male/female in each age group per grid square with country totals adjusted to match the corresponding official United Nations population estimates that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat (2019 Revision of World Population Prospects). "NoData" values represent areas that were mapped as unsettled based on the outputs of the Built-Settlement Growth Model (BSGM) developed by Nieves, J. J et al. 2019 and 2020
The mapping approach is Pezzulo, C. et al. Sub-national mapping of population pyramids and dependency ratios in Africa and Asia. Sci. Data 4:170089 doi:10.1038/sdata.2017.89 (2017)
Filenames: Example arm_f_5_2020_constrained_UNadj.tif People per pixel (PPP) for female age group 5 to 9 years (f_05) in Armenia for year 2020. For other datasets, m = male, 00 = age group 0 to 12months, 01 = age group 1 to 4 years, 80 = age 80 years and over
