Household density per ha - Flanders - Condition 2019

This map indicator shows an estimate of the number of households per hectare, corrected per municipality. The same basic data are followed for this indicator as for the indicator ‘Population density per ha’. The dataset of the population describes the location and the number of inhabitants per address on the basis of a points file. This file is created by Digitaal Vlaanderen (DV) on the basis of data from the National Register. The location of the addresses is determined by a geocoding of the addresses based on CRAB (CRAB population numbers version 0.1). The proxy for the number of households is the number of records in the dataset (i.e. number of addresses) whose number of inhabitants is not equal to ‘0’ or ‘NoData (-99)’. Addresses for which the number of inhabitants is equal to 0 are addresses from the CRAB database that do not appear in the national register and where no one lives. Addresses with a ‘NoData’ value are addresses for which the number of inhabitants is not known exactly. This is the case, for example, for sub-addresses whose population in the national register is only known at house number level and not per sub-address. The total number of households in Flanders according to this assumption is lower than the total number of households reported by the FPS Economy. For this difference, the dataset is corrected at the level of municipalities based on the statistics of the number of households per municipality. For this, the sum of the number of households per municipality is first made on the basis of the points file. Subsequently, the factor of this sum relative to the reported number of households is calculated by Statbel. This factor is then applied to all address points. For example, if in a given municipality 5% fewer households are calculated on the basis of the points file compared to the StatBel statistics, the number of households will be increased by 5% at each point location. This corrected points file is then scaled up to a resolution of 1 ha by making the sum of the corrected number of households for each hectare cell.
