3.1. Data description | |||
The Index of Production in Construction (IPC) measures the changes in the volume of output in the construction sector. The relevant construction activities are included in Section F of the statistical classification of economic activities in the European Community (NACE Rev. 2). In particular, these activities include the complete construction of buildings, the complete construction of civil engineering works, as well as specialised construction activities, if carried out only as a part of the construction process. |
|||
3.2. Classification system | |||
The classifications used in STS is NACE rev.2 |
|||
3.3. Coverage - sector | |||
The following NACE divisions are covered: NACE 41 - Construction of buildings NACE 42 - Civil engineering NACE 43 - Specialised construction activities |
|||
3.4. Statistical concepts and definitions | |||
The main indicator is production in construction. This indicator corresponds to the industrial production index but instead of covering the industrial sector, it covers the construction sector, namely Section F of NACE Rev. 2. |
|||

|||
3.8. Coverage - Time | |||
Data are compiled since 2000. |
|||
3.9. Base period | |||
Base year (year on which weights are based): 2015 Reference year (year when the index equals 100): 2015 The same base and reference years are used for data published locally and that transmitted to Eurostat. |

|||
The data are compiled in index form. |
|
|||
The data are compiled on a quarterly basis. |
|
|||

|||
10.3. Dissemination format - online database | |||
The NSO website offers an online statistical database (StatDB) that provides a more in-depth analysis for the more expert statistical user or researcher. The StatDB requires registration as only registered users can extract data from the database. Registration is free-of-charge. Currently, the Index of Construction Production is not available in this format. |
|||
10.4. Dissemination format - microdata access | |||
In general, index results made available to Eurostat ensure a sufficient degree of representativeness of data. More detailed data than that published locally and internationally are available on request but are subject to the confidentiality clauses. In such cases, data are provided in index form. Micro data are not provided to users. |
|||
10.5. Dissemination format - other | |||
Data are transmitted to Eurostat on a quarterly basis. |
|||
10.6. Documentation on methodology | |||

|||
11.2. Quality management - assessment | |||
Aspects of quality are divided into several steps.

Revisions are carried according to the European Business Statistics Regulation. Internal procedures are also established.

Major revisions may also be done but this will be on an exceptional basis. A revision calendar does not exist. |
|||
17.2. Data revision - practice | |||
In practice, routine revisions are done when actual data are received and estimates are replaced. The below Quality Performance Indicators (QPIs) were obtained using annual growth rates for Q4 2018 as the latest release. To calculate the revisions, the previous 15 quarterly periods were used. Unadjusted annual growth rates: Mean Revision (MR): -0.92 Mean Absolute Revision (MAR): 1.28 Relative Mean Absolute Revision (RMAR): 0.68 |
|
|||

|||
18.3. Data collection | |||

Validations of format and file structure checks and intra-dataset checks are checked with the use of in-house excel sheets and access databases. Revisions analysis is also carried out for every data transmission sent to Eurostat using in-house access queries. When data revisions are significantly large, a short explanation is also given to Eurostat. |
|||
18.5. Data compilation | |||
Data are provided by the National Accounts unit. |
|||
