  • PopulationGridsMax Friedrich Hartmann@mxfh
  • Talking Points• Aggregation and Disaggregation of Population Data• Data Sources
  • 03 Population GridsDisaggregation?Aggregation?Dasymetric Map ?Raster!
  • 04 Population Grids Gridded Population of the World, version 3 (GPWv3) World Population Density 2010 (Estimate) http://sedac.ciesin.columbia.edu/gpw/

  • 06 Population GridsChoropleth mapping dot mapping proportional symbols Conventional cartographic population mapping techniques Filipe Batista e Silva
  • 07 Population Grids Spain - Population Density (NUTS-3 Level) http://epp.eurostat.ec.europa.eu/statistics_explained/index.php/Population_grids
  • 08 Population GridsDrawbacks of Conventional Population Mapping Filipe Batista e Silva • Size of areas is partly very heterogenous since they are only affected by administrative borders and zoning • Structural phenomenos can be hidden by accident or deliberately Modifiable Areal Unit Problem (MAUP) Gerrymandering • Within a single statistical area homogenity is assumed which does’t exist in the real world distribution • Important land features (rivers, mountain ranges) are not considered
  • 09 Population Grids Geostat Population grid 2006 http://epp.eurostat.ec.europa.eu/statistics_explained/index.php/Population_grids
  • 10 Population Grids Quelle: UMS 2414 RIATE (CNRS-DATAR-Université Paris 7 (Hrsg.): ESPON-Projekt 3.4.3 - The modifiable areas unit problem. Endbericht 2006
  • 11 Population Grids Geostatistical create a spatial reference frame for all kinds of geodata. The are independent from admin borders and allow a purely topic related area selection. Ingrid Kaminger, Auf dem Weg zu einer rasterbasierten Regionalstatistik in Europa
  • 12 Population GridsAdvantages/Disadvantages of gridsAdvantages• Ready for universal use• Ready for automation• Independent of borders• High resolutionDisadvantages• Privacy Issues• Process of creating the grid is quite complex
  • 13 Population Grids Aggregation Credits: Eurostat GEOSTAT

  • 15 Population Grids Erich Wonka (2010)
  • 16 Population GridsDisaggregationStatistical data is only available in bigger statistical unitsDesireable is a grid with a fine grid with cells smalle than the area unit.One solution is the reversal of aggregation - disaggregation. (dasymetric mapping)Information density is increases by deduction from know spatial
