3.1. Data description | |||
This indicator is part of the overall STS indicator system which supports business cycle observation. The industrial turnover index aims to show the development of turnover as value and as volume information. |
|||
3.2. Classification system | |||
NACE Rev. 2. |
|||
3.3. Coverage - sector | |||
Local units with 50 employees or more in Sections B and C of NACE Rev. 2 are covered. |
|||
3.4. Statistical concepts and definitions | |||
The turnover indicators aim to show the development of turnover (domestic and non-domestic) as value and (adjusted by price changes) as volume information. The basic information collected is turnover in value excluding VAT. |
|||
3.5. Statistical unit | |||
Local unit and local-kind-of-activity unit. |
|||
3.6. Statistical population | |||
Local units of Sections B to C of NACE Rev. 2 according to the business register. |
|||
3.7. Reference area | |||
Country as a whole. The decisive criterion for the geographical assignment is the place of the local unit. In general, foreign local units do not contribute to the German industrial turnover. However, turnover from selling goods which were produced in foreign local units as commission order is considered to be German industrial turnover when the reporting unit keeps being the owner of the input materials needed for production although physical production is relocated abroad. |
|||
3.8. Coverage - Time | |||
Since 1962. |

|||
10.7. Quality management - documentation | |||
Standardized quality reports are published on the website of destatis: |
|
|||
11.1. Quality assurance | |||
The data of German official statistics enjoy a reputation of high reliability in Germany and abroad. Destatis has committed itself to assure and further enhance the level of quality already attained. In order to achieve this task – also in the ESS – the activities of destatis are based on quality guidelines. To assure quality in the long term, destatis applies a variety of systematic quality assurance measures, among others the European Statistics Code of Practice.
Detailed descriptions can be found here: |
|||
11.2. Quality management - assessment | |||
The quality of the indicator is satisfactory. The monthly report of local units in industry (including mining and quarrying) is conducted in a decentralized manner. The statistical offices of the Länder are responsible for collecting, checking and processing the respective Länder data. The Federal Statistical Office is entrusted with the methodological preparations for and the development of the statistics and it collates the Länder results in order to produce and publish federal results as well as to calculate indices. |
|
|||
12.1. Relevance - User Needs | |||
The industrial turnover index ranks among the most important indicators for monitoring and analyzing the short-term economic development in Germany. The economic-political sensitivity of these data requires a particularly high degree of timeliness and accuracy in reporting. National users are therefore in particular the Federal Government, more specifically the Federal Ministry for Economic Affairs and Climate Action and the Federal Ministry of Finance, the German Central Bank, the German Council of Economic Experts, economic research institutes, universities, trade associations, the media, and also the interested public and international users such as Eurostat. |
|||
12.2. Relevance - User Satisfaction | |||
Destatis conducts user satisfaction surveys in various sectors of statistics. The Statistical Advisory Committee (Statistischer Beirat) represents the interests of the users of federal statistics and regularly consults with destatis. Additionally, user satisfaction is measured by the number of monthly visits on specialized publications on the website of destatis and the respective number of printed products sold or downloads, quarterly downloads from the on-line database “GENESIS”, downloads of the Statistical Yearbook sorted by chapters and the number of external queries via the costumer management system. |
|||
12.3. Completeness | |||
STS requirements according to EU regulations and national laws are fulfilled. |
|
|||
13.1. Accuracy - overall | |||
There is the trade-off between accuracy and timeliness. Therefore, the monthly production indices are provisional. Still, they comprise just fewer than 10% of estimated data. Errors may occur from incorrect reports of the enterprises, human errors during the data editing process, imputation errors. |
|||
13.2. Sampling error | |||
Not relevant since the monthly report of local units in industry (including mining and quarrying) - the main data base for the calculation of the turnover index - is a census of local units with 50 persons or more employed. |
|||
13.3. Non-sampling error | |||
The response rate for the first preliminary results is approximately 90%. It reaches 95% after the first revision and almost 100% after the quarterly revision. The response is obligatory. Otherwise, fines can be imposed up to EUR 5,000. |
|
|||
14.1. Timeliness | |||
Preliminary results are published 37 days after the end of the reference month (t+37). |
|||
14.2. Punctuality | |||
All publication deadlines are met. |
|
|||
15.1. Comparability - geographical | |||
Consistent time series of the recent base year are available since 1991 since Germany is covered as a whole. |
|||
15.2. Comparability - over time | |||
Consistent time series of the recent base year are available since 1991. Time series prior to 1991 refer to the former territory of the Federal Republic of Germany. There are no breaks in the time series. |
|||
15.3. Coherence - cross domain | |||
The data are coordinated with the calculation of the national accounts. The turnover index is needed for the estimation of the quarterly GDP. The index formula (Laspeyres, rebasing every five years) is used for each indicator in the industry. Thus, the base year and the index reference period coincide. Furthermore, all indices use the same classification framework and are consistent with the definitions, scope, classifications, and timing of recording as required by the STS-Regulation. |
|||
15.4. Coherence - internal | |||
The components are coherent with all aggregates. This is valid for the raw data. The aggregates of working day adjusted data and seasonal adjusted data are coherent with the MIGs. The NACE 4-digit sectors are coherent with the time series of the NACE 3-digit sectors. The MIGs and the time series of the NACE 2-digit sectors are directly working day adjusted and seasonally adjusted. |
|
|||
It is not possible to determine the costs and loads separately for the turnover index. The cost and burden of all STS- indicators in total were transmitted to Eurostat. The International Standard Cost Model will be used to measure administrative costs by the FSO. |
|
|||
17.1. Data revision - policy | |||
The general revision policy adopted by destatis covers routine revisions, major revisions and non-scheduled revisions. It is found under the following link: https://www.destatis.de/EN/Methods/Quality/GeneralRevisionsPolicy.html The national revision policy is the same as for Eurostat data.
Information on tracking vintages are given on the website of the German Central Bank: https://www.bundesbank.de/dynamic/action/en/statistics/time-series-databases/time-series-databases/745590/real-time-data?statisticType=BBK_RTD&treeId=113205500 |
|||
17.2. Data revision - practice | |||
Data revision follows the revision policy mentioned above. Routine revisions result in revised turnover indices which are published in the following month (i.e. after four weeks), together with the preliminary indices for that month. The revised indices take into account subsequently received data and possible corrections. Monthly revisions amount on average to 0.5 percentage points. A final index calculation in regard to the annual correction is made in April of the following year. The last major revision was conducted in 2024 in the context of the new base year 2021. In the case of regular index rebases, the results and changes in the calculation methodology are presented in detail in the FSO monthly journal “Wirtschaft und Statistik”. |
|
|||
18.1. Source data | |||
The data are based on a statistical survey. The coverage of the survey is updated yearly. The frame on which the source is based is the national business register (Unternehmensregister). The monthly report of local units in industry (including mining and quarrying) is a cut-off survey and exhaustive for all local units with 50 employees or more if their principal activity (value added, alternatively: number of employees) is located in “Industry”. |
|||
18.2. Frequency of data collection | |||
Data for the calculation of the turnover index are collected monthly. |
|||
18.3. Data collection | |||
The data collection is conducted by web-questionnaires, which are sent and collected by the statistical offices of the Länder. Missing responses are requested by telephone contacts or reminders are sent. The questionnaire is called "Monatsbericht für Betriebe im Verarbeitenden Gewerbe (einschl. Bergbau und Gewinnung von Steinen und Erden)" (monthly report of local units in manufacturing industry (including mining and quarrying)). It collects information on turnover, new orders, orders on hand and labour input. |
|||
18.4. Data validation | |||
Data are checked by the statistical offices of the Länder before they are transmitted to the FSO. Plausibility checks are jointly determined by the FSO and the statistical offices of the Länder. They are carried out on the results (i.e. comparison at the level of each time series, calculation of changes in figures compared with the previous year/month) while a review of data quality has already been conducted during the process of index calculation. |
|||
18.5. Data compilation | |||
Estimates for non-response are based on values of the preceding month which are still contained in the current statistical data reported. Basically, they are replaced by the rate of change of data received within the deadlines, which is then included in the index calculation. There are no estimates for grossing-up to population levels. Indices in nominal values are calculated by simple comparison with the figures of the base year. Indices in volume are Paasche-indices. Weights are based on turnover in the year 2021. |
|||
18.6. Adjustment | |||
For seasonal adjustment, version 2.2 of the JDemetra+ software is used. It is recommended for seasonal adjustment within the European Statistical System and the European System of Central Banks. The underlying mathematical-statistical method does not differ fundamentally from the previous X-12-ARIMA procedure. The first stage of the procedure is RegARIMA modelling; unadjusted values at the ends are extended by estimates and, where required, adjusted for outliers. Extending the time series by estimates is required, for instance, for the second stage of the procedure, where centred moving averages are calculated. Seasonal adjustment as such is carried out in the second stage of the procedure. It is an iterative process for smoothing the unadjusted data by means of trend and seasonal filters which are calculated from centred weighted moving averages. The seasonal factors of a specific month are obtained by smoothing the deviations of the unadjusted values from the trend values of that month. The trend values, in turn, are smoothed unadjusted values. There may also be calendar adjustment in the first stage. For that purpose, the number of working days in the current month is determined after deducting holidays; the result is compared with the long-term average of that period. Public holidays that are relevant only in some Länder are weighted using the number of employees in those Länder as a proportion of the total number of employees in Germany. The percentage effect of an additional working or trading day on the unadjusted value is estimated from past values of the relevant set of statistics under RegARIMA modelling. These estimates are used to eliminate the impact of variations in the number of working days in the respective month or quarter from the unadjusted data. The effects of bridging days (days between a public holiday and a weekend), movable school holidays and the weather are not taken into account. Results based on the calendar and seasonal adjustment procedure BV4.1 and trend results according to BV4.1 are published in addition to the results adjusted for calendar and seasonal effects using the X13 JD+ procedure.
software used and version: Calendar and seasonal adjustment based on X13 in JDemetra+ 2.2 model/filter selection: manual times the models and the respective parameters are re-estimated: monthly horizon of revisions: revisions are completed after the yearly correction. The time series is calculated backwards up to 2021. seasonal adjustment decomposition: The underlying model for the seasonal decomposition is multiplicative and only for a few selected time series additive. ARIMA-Model: mostly “airline” model (0 1 1)(0 1 1) critical value for outlier detection: 4 filter length: the Filter lengths (Henderson and seasonal filter) are user defined with the value 17 and 3X9, respectively date of seasonal breaks in the series: There are no breaks in the time series. indirect adjustment via components: The sales volume index for Germany is indirectly adjusted via its components, which are directly adjusted. residual seasonality: The residual seasonality is checked on a yearly basis for the industrial main groups. aggregation: the industrial sales volume index is calculated from the two-digit NACE positions. These are obtained from the four-digit NACE positions. consistency amongst the different levels of breakdown: The consistency is checked regularly on a yearly basis. Deviations are moderate but can vary. |
