 <p>The <em>peanutButter</em> R package was developed by the WorldPop Research Group within the Department of Geography and Environmental Science at the University of Southampton. Funding was provided by the Bill and Melinda Gates Foundation (INV-002697). Ecopia.AI and Maxar Technologies (2020) provided high resolution building footprints based on recent satellite imagery. Gridded age-sex data were provided by the WorldPop Global High Resolution Population Denominators Project led by Alessandro Sorichetta with funding from the Bill and Melinda Gates Foundation (OPP1134076). Development of the <em>peanutButter</em> R package was led by Doug Leasure. Claire Dooley developed the source rasters of building counts and urban/rural settlements. Maksym Bondarenko maintains WorldPop's Shiny server. Professor Andy Tatem provides oversight of the WorldPop Research Group.</p>
