2. Talking Points
• Aggregation and Disaggregation of Population Data
• Data Sources

3. 03 Population Grids
Disaggregation?
Aggregation?
Dasymetric Map ?
Raster!

8. 08 Population Grids
Drawbacks 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

11. 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.

12. 12 Population Grids
Advantages/Disadvantages of grids
Advantages
• Ready for universal use
• Ready for automation
• Independent of borders
• High resolution
Disadvantages
• Privacy Issues
• Process of creating the grid is quite complex

16. 16 Population Grids
Disaggregation
Statistical data is only available in bigger statistical units
Desireable 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
