About the study

In order to improve the research concerning the saving behavior of German households, the Munich Center for the Economics of Aging (MEA) conducts the SAVE survey since 2001 in collaboration with TNS Infratest Sozialforschung. Until 2010, the survey was financed by the Deutsche Forschungsgemeinschaft (DFG). It lays its main emphasis on saving behaviour, old-age provision and wealth creation in Germany. The SAVE-study^[1] makes it possible to explore economic, sociological and psychological interdependences. This means that it collects information about income, wealth and old-age provision and about socio-demographic and psychological characteristics. This information includes e.g. expectations, attitudes and the attitude towards risk of the respondents. Since 2005 SAVE is conducted annually. Since respondents remain the same every year (panel), changes in saving behaviour and investment behaviour of households can be tracked over time. The ninth survey for 2011 was conducted in collaboration with the Institute for Employment Research (IAB in Nuremberg, Germany) (http://www.iab.de/en/), which is the research institute of the Federal Employment Agency. This cooperation lead to the linking of information about employment status and social security contributions to answers in SAVE.

Sample size

Launching the sample in 2001^[1] it was continuously extended in 2003, 2005 and 2006 by inclusion of a new set of households. By the year 2006 the panel reached a high level of stability. In 2007 84% of German households who also participated in 2006 could be interviewed again. In 2008 and 2009 the response rate was even better, namely 89% and 85%. In 2011, 81% of 2010 Respondents were surveyed. Overall, 55% of the participants added in the 2005 refreshment sample, were still in the sample in 2010. The sample size per year is shown in the following table.

Year	2001	2003/04	2005	2006	2007	2008	2009	2010	2011
No. of households	1829	3154	2305	3474	2931	2608	2222	2037	1660

Access to the dataset

The SAVE-dataset is made available to the public by the GESIS - Leibniz-Institut für Sozialwissenschaften for non-commercial use only. Anonymity of the respondents is ensured by all means. Further information about the SAVE-dataset is available on the SAVE homepage where e.g. the yearly questionnaires can be downloaded. There also exists another dataset called „miniSAVE" for the years 2005-2010 which is especially useful for teaching purposes. MiniSAVE provides an easy way to get to know the dataset.

Usage of the dataset linked to the administrative data is subject to several confidentiality rules (see [1]). After the request has been approved by the Federal Ministry of Labour and Social Affairs (BMAS), a contract with the Research Data Centre (FDZ) of the Federal Employment Agency (BA) at the Institute for Employment Research (IAB) allowing the researcher to use the requested dataset on-site has to be signed.
