Household density per ha – Flanders – situation 2013

This map indicator gives an estimate of the number of inhabitants per hectare corrected by statistical sector. The population dataset describes the location and the number of inhabitants per address using a point file. This file is created by Informatie Vlaanderen (AIV) from data from the Rijksregister. The locations of the addresses are determined by geocoding of the addresses based on crab (crab population numbers version 0.1). The total number of inhabitants in Flanders according to this point file is slightly underestimated compared to the actual number of inhabitants in Flanders as reported by the FPS Economy. This shortfall can be explained by the fact that it was not possible to fully link the addresses from the Rijksregister to crab (missing or unknown addresses in crab). For this difference, the dataset is adjusted at the level of the statistical sectors based on the statistics on the number of inhabitants per statistical sector of Statbel. For this purpose, the sum of the number of inhabitants based on the population per adrespunt per sector is first taken. The factor of this sum is then calculated in relation to the number of inhabitants reported by Statbel. This factor is then applied to all population points. For example, if in a given sector a population reduction of 5 % is calculated on the basis of the number of points with inhabitants per adrespunt relative to statistics, the number of inhabitants is increased by 5 % at each point location. This corrected points file is then rescaled to a resolution of 1 ha by adding, for each hectare unit, the sum of the corrected number of inhabitants per address. This geodata layer was replaced in 2021 by a revised version for Condition 2013, in order to remain in line with the updated method used in condition 2019.
