Study title

The addresses of ALLBUS survey respondents form the basis for the allocation of small-scale geodata. With the aid of geocoding (i.e. the calculation of geo-coordinates from the addresses), the point coordinates were linked with external geodata. These geodata originate on the one hand from the geodata provided by the 2011 census (census atlas) and on the other hand from the official noise mapping according to the Bundes-Immisionsschutzgesetz (Federal Immission Control Act). The grid cells of the census atlas assigned to ALLBUS respondents contain information on: • the population (1 km and 100 m) • the average age and proportions of under-18-year-olds and over-65-year-olds (1 km) • the gender ratio (1 km) • the proportion of foreigners (1 km) • household and apartment size and vacancy rate (1 km). For the survey years 2016 and 2018, the small-scale geodata also include census data on a 100m × 100m grid level from the following categories: • Demography • Households • Families • Buildings The small-scale geodata of the ALLBUS 2014 also contain point-related data on: • road traffic noise • rail traffic noise • aircraft noise. The daytime average and night values and the distance to the specified noise source are given as well. The small-scale geo-variables of this data set can be merged with the survey data of the ALLBUS by the identification number of the respondents. Just like the regional identifiers, this data set is subject to special access restrictions, because the small-scale geo-attributes may allow deanonymization of the survey participants. For this reason, the data can only be used on-site in the Secure Data Center of GESIS. You will find more information and contact persons on our website. Please contact the ALLBUS user service first and send us the completed ALLBUS geodata form (see documents), in which you specify exactly which variables you need from the data set. As soon as you have clarified the modalities of data access with the...
