3.1. Data description | |||
This indicator is part of the overall STS indicator system which supports business cycle observation. This index of persons employed shows the evolution of employment in construction activities. Labour input data are compiled at the 4-digit level of NACE Rev. 2 and are calculated for NACE Rev. 2 Sections. Employment data are broken down according to the manual/non-manual breakdown. |
|||

They exclude home workers, family members working less than 1/3 of the average working time (in other words less than 55 hours a month), persons employed by other units to assemble or repair capital assets as well as persons on early retirement. In addition to the total of persons employed, the questionnaire asks for the number of manual workers (inclusive of apprentices). The basic information collected are nominal figures. Active enterprises of all size classes are covered. |

6.1. Institutional Mandate - legal acts and other agreements | |||
The laws regulating the collection, treatment and dissemination of statistical data are the Council Regulation (EC) No 1165/98 of 19 May 1998 concerning short-term statistics with implementing acts (e.g. Commission Regulation No 1503/2006 of 28 September 2006 concerning the definitions) as well as the Federal Statistics Act (1987) and the national Manufacturing Industry Statistics Act (ProdGewStatG of 2002) with several amendments. |
|||
6.2. Institutional Mandate - data sharing | |||
The results are compiled in close cooperation with the statistical offices of the federal states (Bundesländer). Data sent to Eurostat may contain confidential data to compile the European aggregate. |
|
|||
7.1. Confidentiality - policy | |||
Confidentiality is guaranteed by section 16 of the Federal Statistics Act. It requires that respondents must be informed about their rights and obligations in providing statistical information. This rule is strictly followed. It also applies to the notification that individual data are only used for statistical purposes and - subject to protection procedures - for scientific purposes. Furthermore, Chapter V “Statistical Confidentiality” of the REGULATION (EC) No 223/2009 of the European Parliament and of the Council applies. |
|||
7.2. Confidentiality - data treatment | |||
As regards the confidentiality of data, methods of primary and secondary confidentiality checking have been developed and are being used. For business and agriculture surveys, disclosure risk assessment is based on concentration-rules. Cell suppression is used to prevent residual disclosure in tables for dissemination. |

|||
11.1. Quality assurance | |||
The data of German official statistics enjoy a reputation of high reliability in Germany and abroad. The FSO 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 the FSO are based on quality guidelines. To assure quality in the long term, the FSO 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 monthly survey in the construction sector 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 methodological preparations and the development of the statistics, and it collects the Länder results in order to produce and publish federal results as well as to calculate indices. |
|
|||
12.1. Relevance - User Needs | |||
The quarterly data of employment in construction is an important early indicator for monitoring and analyzing the short-term economic development in Germany. The user is Eurostat. |
|||
12.2. Relevance - User Satisfaction | |||
The FSO 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 the FSO. Additionally, user satisfaction is measured by the number of monthly visits on specialized publications on the website of the FSO 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 | |||
Deviations between the preliminary and the final results are marginal. |
|||
13.2. Sampling error | |||
Not relevant since surveys are conducted with a census above a cut-off threshold. |
|||
13.3. Non-sampling error | |||
A bias could occur because only enterprises with 20 or more persons employed are surveyed. Unit-non-repsonse has no impact on the quality because the response rate is close to 100% and an estimation procedure compensates the remaining non-response. |
|
|||
14.1. Timeliness | |||
The first preliminary results for hours worked are published approximately 60 days after the end of the reference period. Data are to be delivered by the reporting units up to the 10th day after the end of the reference period. |
|||
14.2. Punctuality | |||
All publication deadlines are met. |
|
|||
15.1. Comparability - geographical | |||
Results for federal states (Bundesländer = NUTS 1) are directly comparable to each other. |
|||
15.2. Comparability - over time | |||
Consistent time series are available since 2005. |
|||
15.3. Coherence - cross domain | |||
Coherence with National Accounts is only partly given (because of different data collection and estimation methods). |
|||
15.4. Coherence - internal | |||
Internal coherence is given (sub-aggregates add up to the main aggregate). |
|
|||
DESTATIS estimates the hours used by DESTATIS for this indicator as 30 person hours per month. |
|
|||
17.1. Data revision - policy | |||
The general revision policy of the Federal Statistical Office is published under the following URL: https://www.destatis.de/EN/Methods/Quality/GeneralRevisionsPolicy.html This policy applies to national publications and data sent to Eurostat. |
|||
17.2. Data revision - practice | |||
At the first publication all results are considered provisional. With every publication two former results are revised, but still considered provisional. Results are considered final with the third revision 11 months after the reference period.
The national publication is split in diffferent aggregates that are published at different dates. The national results are considered final after the second revision. |
|
|||
18.1. Source data | |||
The persons employed in construction activities are obtained for local-kind-of-activity units based on a primary survey of all enterprises in NACE Section F with 20 or more persons employed, which is complemented by administrative data (business register) for small units. |
|||
18.2. Frequency of data collection | |||
Monthly in the main construction activity and quarterly in the building completion and installation activity |
|||
18.3. Data collection | |||
The data collection is done by Internet questionnaires (IDEV), which are sent and collected by the statistical offices of the federal states (Statistische Ämter der Länder). The administrative data to complement the survey is transmitted monthly. |
|||
18.4. Data validation | |||
The validation (plausibility checks) is done by the statistical offices of the Länder with a standardised It-Programme. |
|||
18.5. Data compilation | |||
Estimates for non-response are based on reported values of the preceding period. The impact of the completion and installation activity in monthly data is taken into account. |
