- Indicators on district level
For all DEAS waves, indicators of regional context on a NUTS3-level (Kreise) can be matched to take the geographical embeddedness of the respondents into consideration (for example, in multi-level analyses, or as controlling variables). The indicators are compiled by the Federal Institute for Research on Building, Urban Affairs and Spatial Development in their indicator system INKAR. The list of all structural characteristics available can be found on www.inkar.de (German only).
- Indicators on street or postal code level
Further, starting with DEAS wave 2002 more detailled regional context information on the level of anonymous residential quarters are available. As this address data is highly sensitive, the data matching process with the living-quarter related data collected by microm Micromarketing-Systeme und Consult GmbH (Neuss) and infas 360 GmbH (Bonn) took place under strict obedience of the rules of data protection, i.e. the separation of address and survey information. These micro-geographical data offer a wide range of indicators at a spatial scale corresponding to the zip-code level. Most of the indicators are estimates of neighbourhood characteristics such as type of residential area, social structure of inhabitants, predominant social milieus or purchasing power and level of unemployment.
For reasons of data protection, working with these regional indicators is only possible at a specifically protected user working station at the premises of the DZA. Should you be interested, please contact the FDZ-DZA team.
