Calculation logic based on level

EXACT

  Each datum is memorized with the relative GPS coordinate, so the calculation is exact.

CENSUS DISTRICT

The census district is the minimum unit managed by ISTAT. Having demographic data, these are stored with BUILD LINKING logic (see below).

WARDS

In South Africa, wards are geopolitical subdivisions of municipalities used for electoral purposes.

MUNICIPAL

The data at the municipal level, being referable to the population, are placed on the map according to the population calculated at the census district level, so also the data at the municipal level acquire a good accuracy.


BUILD LINKING

For each census district, from the map the residential buildings are read and their size are estimated. At the end of this calculation each building will have a weight in relation to the other buildings of the same census district.

In addition, on all residential areas, the system creates fictitious buildings equally distributed in it.

Having the population data for the census district this will be distributed on the buildings in relation to their weight.

Given that by now the cartography reports with good accuracy the buildings on the territory this methodology gives an excellent precision. In the case in which the census district indicates a population, but for the same the cartography does not show any building (it can happen in isolated areas of the countryside) the system, in order not to lose these values, creates fictitious buildings equally distributed in the census district.


As you can see in the following example image the areas with fewer houses, parks or squares, are those with a lighter color, so with low population density.
