The global human population is growing by over 80 million a year, and is projected to reach the 10 billion mark within 50 years.
The vast majority of this growth is expected to be concentrated in low income countries, and primarily in urban areas. The effects of such rapid growth are well documented, with the economies, environment and health of nations, amongst others, all undergoing significant change. High resolution, contemporary data on human population distributions and their compositions are a prerequisite for the accurate measurement of the impacts of population growth, for monitoring changes and for planning interventions. The WorldPop project was initiated in 2013 to unite the continent-focussed AfriPop, AsiaPop and AmeriPop projects, with an aim of producing detailed and freely-available population distribution and composition maps for the whole of Central and South America, Africa and Asia.
WorldPop data are used by many international agencies, including the International Red Cross, Bill and Melinda Gates Foundation, FAO, UNDP, UNFPA, UNOCHA, CDC, China CDC, WFP, WWF, MSF, IOM, PMI, iMMAP, NASA, Population Council, Clinton Health Access Initiative, DFID, USGS, USAID and IDMC.
