German General Social Survey ALLBUS - Small-scale Geodata 2014, 2016 and 2018

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.
