Scholarcy highlights

  • High resolution, contemporary data on human population distributions, their characteristics and changes over time are a prerequisite for the accurate measurement of the impacts of population growth, for monitoring changes and for planning interventions
  • Planning for elections, calculating per-capita gross domestic product, the denominator in disease incidence rates, assessing natural disaster impacts, measuring demand for services—underlying all of these activities and countless more is the need for ongoing subnational scale data on population sizes and characteristics
  • In 2015 the sustainable development goals were launched, a set of aspirational health and development goals spearheaded by the United Nations
  • All SDGs are based on ensuring a certain percentage of the population has access to specific services or resources, or achieves a certain level of social, economic, or physical health, increasing further the need for reliable demographic data
  • The broad focus of the SDGs across fields such as climate change, disaster response and access to services is driving a need to move beyond administrative unit-based analyses to enable flexible integration with datasets on features such as land use, flooding and service locations
  • Mobile phone call data records are enabling more timely mapping of changing population densities and migration patterns, national household survey data are providing a valuable input to large area demographic mapping, while satellite data are supporting the development of urban growth mapping
