8.1 Release calendar | ||||||||||||
Every year, in December ISTAT publishes a release calendar providing the precise release dates for the coming year. The calendar is distributed to the press and is available free of charge to interested parties. The calendar is also disseminated on ISTAT's Internet website. During the first part of the year the required one-quarter-ahead approximate release dates are disseminated on the Internet on the IMF's Dissemination Standards Bulletin Board, and the public are informed of this through a regular notice published in the ISTAT press release "Statistica Flash" | ||||||||||||
8.2 Release calendar access | ||||||||||||
Press release calendar: http://www.istat.it/en/information/journalists/press-calendar | ||||||||||||
8.3 Release policy - user access | ||||||||||||
Data are released simultaneously to all interested parties by issuing the press release " Produzione industriale" which is provided, on an embargo basis, to the media at a press conference (using “locked room” method) 30 minutes prior to general release. The press release (Italian version and English version) is subsequently posted on the ISTAT Internet website. Data are transmitted to Eurostat by teletransmission no later than 40 days from the end of the reference month according to the European Council Regulation 1158/2005. If National release is not scheduled at the same time data are sent to Eurostat as confidential. | ||||||||||||
9. Frequency of dissemination | ||||||||||||
Data are disseminated monthly | ||||||||||||
10. Accessibility and clarity | ||||||||||||
10.1 Dissemination format - News release | ||||||||||||
Current data is presented in the monthly press release Produzione industriale. There, figures and tables are disseminated with the data to facilitate the analysis. Analysis of current-period developments is included with dissemination. Data are disseminated in unadjusted form, adjusted for working days (total index, indices by MIGs, branches at four digit level of NACE Rev. 2 classification), and in a seasonally-adjusted form.The Italian version of the Industrial production press release includes also a data file, the weighting structure, a methodological note. Press releases: http://www.istat.it/en/archive/industrial+products | ||||||||||||
10.2 Dissemination format - Publications | ||||||||||||
Data are made available also through yearly publications: Annual Report and Annuario Statistico Italiano (Italian version) Annual Report: http://www.istat.it/en/archive/annual+report Annuario Statistico Italiano: http://www.istat.it/it/archivio/107568 | ||||||||||||
10.3 Dissemination format - online database | ||||||||||||
Series are included in the ISTAT on-line Database (http://dati.istat.it/?lang=en). The on-line database I.Stat is open and free, statistics are organised by theme in a two-level hierarchical tree. Data are presented in aggregate form in multidimensional tables; acting on variables, reference periods and the arrangement of heads and sides users can create custom tables and graphs. The system can be searched by keyword, theme and region. More information available in the User Guide http://dati.istat.it/ModalHelp/OECD/WBOS%20User%20Guide%20(EN).PDF | ||||||||||||
10.4 Dissemination format - microdata access | ||||||||||||
Before data dissemination, validated microdata are stored in the repository of the Institute, ARMIDA. The repository ARMIDA (Archive of validated microdata) was established with the main objective of preserving and documenting the data produced by Istat surveys, and has subsequently supported the objective of disseminating data. The data archived in ARMIDA supplies, in fact, the different channels for the dissemination of microdata (for internal use at the Institute through the "Memorandum of access to microdata of ARMIDA" internal users ", for authorities in Sistan, for research files, for standard files, etc.). The micro-data stored in ARMIDA are also used to respond to requests of external users submitted to the Adele laboratory http://www.istat.it/en/information/researchers/analysis-of-individual-data | ||||||||||||
10.5 Dissemination format - other | ||||||||||||
Data are sent to Eurostat in Gesmes file and disseminated as national data in the Eurostat's database (Eurobase, theme Industry, trade and services, sub-theme Short-term business statistics) and a .pdf copy of monthly bullettin is available for the period January 2007- March 2011 (data refer to October 2005-December 2010) at http://www.istat.it/it/archivio/18167. | ||||||||||||

14. Timeliness and punctuality | ||||||||||||
14.1 Timeliness | ||||||||||||
The official release is published on average 40 days after the end of the reference period; data are transmitted to EUROSTAT within 40 days, using, when needed, an embargo clause; data are provisional at the time of the Press Release in which they are reported. They are then revised and become final after 3 years. | ||||||||||||
14.2 Punctuality | ||||||||||||
Within 40 days, as required by Eurostat | ||||||||||||
15. Coherence and comparability | ||||||||||||
15.1 Comparability - geographical | ||||||||||||
European definitions are used and they apply in the whole national territory | ||||||||||||
15.2 Comparability - over time | ||||||||||||
Consistent time series data are available for a long period of time (since January 1990). When changes in source data, methodology and statistical techniques are introduced, historical series are reconstructed as far back as possible. | ||||||||||||
15.3 Coherence - cross domain | ||||||||||||
Comparisons are made with the evolution of turnover and new orders indices. Results for these comparisons show good level of coherence for main aggregates. | ||||||||||||
15.4 Coherence - internal | ||||||||||||
Aggregates are always consistent with their sub-aggregates but for seasonnally adjusted data internal coherence could not be always ensured as direct method is used | ||||||||||||
16. Cost and Burden | ||||||||||||
In 2014 the cost of Industrial Production Index survey was 25,000 hours per year. An estimation of time burden for reporting enterprise is around 30 minutes each month. | ||||||||||||
17. Data revision | ||||||||||||
17.1 Data revision - policy | ||||||||||||
The general revision policy is predetermined and reasonably stable from year to year and is adopted in order to incorporate udpated information. It consists of: - routine revisions. Data are provisional at the time of the press release, they are revised one month later for taking into account increase in the response rate. In addition, revisions of the last three years raw data is performed once a year for improving indicators using information coming from enterprises and other source. - major revisions. Performed every five years, in correspondence of introduction of a new base year; they take into account new weighting systems, sample adjustments in enterprises and products lists. At the time of each dissemination, users are informed whether data are preliminary or revised and the reason why data are revised (e.g. availability of additional data, major revisions declared by enterprises or other sources). Generally, major changes in methodology, source and statistical techniques are announced in ad hoc publications. A detailed notification of methodological changes is also provided through seminars and papers disseminated throughout the scientific community. Non-scheduled revisions and major errors are published by specific notes. Vintage database was stopped when base year 2010=100 has been introduced (March 2013) and it will be disseminated again in the future. In February 2015, the Italian National Institute assigned to an internal working group to define new standard of revision policy and a common set of revision measures. Coherence of the revision policy is respected for data released nationally and transmitted to Eurostat. | ||||||||||||
17.2 Data revision - practice | ||||||||||||
A paragraph called “Revisioni” is attached to every press release in Italian. It contains a methodological note on revisions (revision policy, source, periodicity, etc.) and the results of the revision analysis for the current period presented. Major revision dues to mistakes are made known to the public after the event. For the year 2014, the monthly revisions of the raw general index varied from a minimum value of -0.2 points to a maximum of +0.2 points. After the revision of the last three years, the final annual data percentage change of 2014 raw general index changed from -1.2% to -1.0%. | ||||||||||||

Data are collected monthly. | ||||||||||||
18.3 Data collection | ||||||||||||
| ||||||||||||
18.4 Data validation | ||||||||||||
Time series checks are used for plausibility of data validated. Integrity of files structure and used codes is ensured by extractions made from a database respecting integrity constraints. | ||||||||||||
18.5 Data compilation | ||||||||||||
| ||||||||||||
18.6 Adjustment | ||||||||||||
The raw indices are trading days adjusted and corrected for seasonal effects by TRAMO-SEATS procedure, version 2010 for Linux. Working days adjustment series are estimated down to 4 digit level, seasonal adjustment series are calculated for total, MIGs and 2 digit level. Adjustment models are completely reviewed at the beginning of each year (with the release of February data) and parameters are re-estimated every month. Each month, seasonally adjusted series are revised from January 2001. A Reg-Arima approach is used for working days and seasonal adjustment. Calendar adjustment is performed by using our country specific calendar which also take into account national holidays. No calendar adjustment is performed where no significant effect is found. Leap year and moving holidays like Easter are adjusted. Outliers (additive outliers, temporary changes, level shift) are manually fixed at the beginning of the year when seasonal adjustment models are revised. The critical value for the outlier detection and the filter length are automatically chosen, whereas model/filter selection is manual. Both additive and multiplicative seasonal adjustment decomposition are used. Except for total consumption goods series, which is indirectly derived by weighted sum of non-durable and durable goods, all other series are directly adjusted. Whenever indirect adjustment is performed, a residual seasonality test is performed and checked. | ||||||||||||
