On the basis of data from the population and building and dwellings registers, the new population census system provides since 2010 diverse statistical information on households, persons, buildings and dwellings. Selected characteristics from the extensive data stock are analysed at hectare resolution and transformed into geodata, which is then made available.
In GEOSTAT's standard range of data based on the Population and Household Statistics (STATPOP) 69 individual variables and 8 household variables (since 2012) aggregated by hectare are available.
Building coordinates and the federal building identification number (EGID) are some of the characteristics listed in the federal building and dwellings register (BDR). The EGID also applies to the population registers so that persons can also be assigned coordinates. This means that results from the population and household statistics (STATPOP) can be analysed and visualised in high spatial detail for the whole of Switzerland.
For the dissemination of data, statistical information on the population and households is analysed by using a hectare grid. For each hectare, the coordinates of the south-west corner (bottom left) are used as an identifier. Every characteristic or numeric value shown for each cell relates to occurrences within the 100x100 m surface of this cell, i.e. the number of persons, for example, whose coordinates are found in the square in question. In this way they build an aggregation of the individual records from a survey that are allocated to each grid cell or hectare.
For reasons of data protection, certain restrictions apply to variables from the population and household survey with regard to forwarding raw data and cartographic representations based on a measurement in hectares. To ensure data protection, absolute values from 1 to 3 are shown in standard tables as a group or cluster with the value of "3". Where their use can be justified, data that have not been grouped together in this way can be used for statistical, research and planning purposes after conclusion of a data protection agreement.
