Timeliness, transparencyThe first results from the section “General Issues” are released in the autumn of the reporting year. The first results from the section “Household Diary” are released two years after collection. Scientific Use Files (SUF) are released about 6 months after the results are published.
Data set is available from the Research Data Centre. For scientific use, microdata of the EVS are available from the Research Data Centre as Scientific Use files (SUF) for scientists from Germany, for remote data processing and for on-site workplaces (guest scientists). All these data are with costs.
Conditions of access
only for projects limited in content and time (3 years at the most), data available following completion of an application and research contract; most data with fees.
Time depends on individual case
Anonymised microdata and aggregated tables (reports or dynamic tables) are available online without any preconditions.
Scientific Use Files: CSV data files
Data is only available in German. English documentation can be found here: http://idsc.iza.org/metadata/HTML/469/survey0/index.html
Wave 1: Data collected in 1962/63 with a sample size of 34,000 households. Only a public use file is available.
Wave 2: Data collected in 1978.
Wave 3: Data collected in 1998 with a sample size of 62,150 households.
Wave 4: Data collected in 2003 with a sample size of 59,713 households.
Wave 5: Data collected in 2008 with a net sample size of 58,984 households.
For waves 2-5, only scientific use files and on-site access are available.
Quota sample: first into the 16 federal states, then according to the type of household (single, multiple persons, etc.), social position of the head of household, and household net income.
all German households with a net household income below 18,000 Euro per month

Sampling error: for the total results less than 0.5%
Non-sampling error: controlled by plausibility checks and budgeting
Non-response: Statistical units: in total 24%, therefrom within the reporting period: 6.5%
In principle, the IES 2008 is comparable with all waves in the past. There were minor changes, for example in the process of contacting the respondents. Results for the East German federal states are comparable for the wave 1993 and later only.
The Sample Survey of Income and Expenditure (IES) is an official statistic survey describing the economic situation of households in Germany. It consists of a very large sample and records incomes in a differentiated way by a quota sample that is stratified by social groups. Accordingly, it provides representative data that are deeply structured and in high quality.
Differentiated analyses are possible for nearly all household types, with the exception of people living in institutions. Households with a monthly net income of more than 18,000 Euros are not considered because the data would not be statistically reliable. Foreigners are not sampled representatively.
