3.1. Data description | |||
Services producer price indices (SPPIs) measure quarterly changes in the prices of services provided by enterprises to other enterprises and to persons representing enterprises. They cover business-to-business transactions (BtoB), thus leaving out sales to private consumers. They are used as a deflator too. |
|||
3.2. Classification system | |||
NACE Rev. 2. CPA 2.1 |
|||
3.3. Coverage - sector | |||
Main and secondary activities of the NACE Rev. 2 industries covered: in Section H: H49.4; H50.1+H50.2 (sum); H51; H52.1; H52.24; H53.1; H53.2; in Section J: J61; J62; J63.1; J63.9; in Section M: M69.1+M69.2+M70.2 (sum); M71; M73; in Section N: N78; N80; N81.2. |
|||
3.4. Statistical concepts and definitions | |||
List and definition of variables: Output prices for services delivered to customers that are enterprises or persons representing enterprises are collected (Business-to-Business). Domestic and non-domestic services are monitored. The prices are the effective transaction prices reflecting the revenue received by the producer for services actually sold to customers. They exclude taxes (VAT) whereas they include subsidies on products received by the producer. Moreover, they take into account any applicable discounts, rebates, surcharges, etc. applied to the customers. Planned changes in the information collected: None Accounting conventions: By definition, the prices are the effective transaction prices reflecting the revenue received by the producer for services actually sold to customers. They exclude taxes (VAT) whereas they include subsidies on products received by the producer; discounts, rebates and surcharges applied to the customers. Data refer to calendar quarter. |
|||
3.5. Statistical unit | |||
Reporting unit: Service enterprise Observation unit(s): Enterprise’ activities (primary or secondary) according to service products sold in CPA classes/categories are observation units. |
|||
3.6. Statistical population | |||
Italian Business Register (SBS) according to the NACE Rev. 2 Groups/Classes activities listed above is used as the sampling frame for SPPI: H49.4; H50.1+H50.2 (sum); H51; H52.1; H52.24; H53.1; H53.2; J61; J62; J63.1; J63.9; M69.1+M69.2+M70.2 (sum); M71; M73; N78; N80; N81.2. Indices have been developed independently for service sectors, which is why the used sampling method varies by sector. For the majority of NACE sectors covered, reporting units have been selected by non-probabilistic sampling (cut-off method); for few sectors, reporting units have been selected by probabilistic sampling. |

The quality assurance framework is based on the contents of the document "Quality guidelines for statistical process”, December 2012. Istat reference framework for quality policies relies on the European Statistics Code of Practice adopted in 2005 (last revised in 2017), on the Eurostat Quality Definition and on the recommendations of the LEG on Quality. The Data Quality Assessment Framework, developed by the International Monetary Fund, also represents an important reference. Following the principles of the European Statistics Code of Practice, Italy has adopted the Italian Code of Official Statistics in order to promote quality improvements of the statistics produced by the Italian National Statistical System. (Directive No 12/COMSTAT in Italian Official Journal No. 23, General Series of 29 January 2022). In accordance with Eurostat Quality Definition, the requirements of statistical products are:
A description of methodology and sources used in preparing statistics is also contained in the Information System for Survey Documentation and Quality Control (SIQual). |
|||

12.2. Relevance - User Satisfaction | |||
Not available | |||
12.3. Completeness | |||
Requirements according to EU regulations and national laws are fulfilled. |
|
|||
13.1. Accuracy - overall | |||
Samples are designed with the cut-off method for the majority of NACE sectors covered. Accuracy can be evaluated relying on the non-sampling error component; component referring to sampling errors is not measured. Non-sampling errors are reduced or eliminated in the collection phase using an electronic questionnaire that helps both debugging and aiming at an increase of the response rate of enterprises. Data check procedure is as well very effective. The response rate is very high for each NACE sector. |
|||
13.2. Sampling error | |||
Not applicable/measured as a non-probability sampling method (cut-off) is used for the majority of NACE sectors covered. |
|||
13.3. Non-sampling error | |||
The response rate varies from 80% to 100%, according to the different NACE classes. |
|
|||
14.1. Timeliness | |||
Data are released about 2 months after the end of the referring period. | |||
14.2. Punctuality | |||
Releases delivered on time during the year |
|
|||
15.1. Comparability - geographical | |||
Not applicable, only national level. |
|||
15.2. Comparability - over time | |||
SPPIs are comparable over time for the entire length of time series. | |||
15.3. Coherence - cross domain | |||
It is possible to compare the results of some SPPIs activities with the corresponding ones of the turnover index or the consumer price index but these cross-checks often can give different results because the indexes are computed according to different targets and methodologies. |
|||
15.4. Coherence - internal | |||
SPPIs are internally coherent. Each SPPI is computed as weighted average mean (Laspeyres type index) of sub-indexes, therefore internal coherence is straightforward. Moreover the coherence is achieved annually updating weights (indexes are annually chain linked). |

The cost estimate is compiled in terms of total number of hours worked (THW). It is equal to the product of three terms: (total) Annual Working Days (AWD), (total) Hours Worked per Day (HWD), Number of Persons involved in the Survey (NPS).
The burden estimate is compiled in terms of total number of minutes (TNM) taken to fill in the (web) questionnaire. The burden is applied to respondent, i.e. the person who fills in the questionnaire on behalf of the enterprise. To estimate it, two elements have been taken into account. The former distinguishes between beginner and expert respondent, to point out respectively the person who fills in the web questionnaire for the first time and the one who is familiar with filling in the form. The latter, closely concerns the information that have to be provided. On average, by combining these two elements, the time spent to fill in the questionnaire (just the burden) is estimated in terms of total number of minutes between a minimum and a maximum threshold.

17.1. Data revision - policy | |||
Quarterly, final data are disseminated as indices. |
|||
17.2. Data revision - practice | |||
At present time, Services producer price indices are both not revised and both not seasonal adjusted. |
|
|||
18.1. Source data | |||
Data are collected through a statistical survey or are obtained from an administrative DB. SBS is used as a frame. The survey is conducted on the basis of a sample (based both non-probabilistic design – for the majority of NACE sectors – and on probabilistic one). Criteria for stratification: - Non-probabilistic design: the sample is drawn by a turnover cut-off (with a census above the cut-off). The chosen threshold guarantees a good/sufficient coverage in terms of turnover; - Probabilistic design: enterprise turnover is used to create strata in which enterprises are chosen with a probabilistic approach. Thresholds vary from 80% to 98% according to the different sectors. The sample of services and the list of enterprises are updated yearly. |
|||
18.2. Frequency of data collection | |||
Quarterly | |||
18.3. Data collection | |||
The questionnaires are different according to the economic sector they refer to collected through a web portal called Portale Imprese. Respondents need to login for insert data in the web questionnaire. |
|||
18.4. Data validation | |||
Before compiling each index, data are validated by observing both levels and prices rates of change. | |||
18.5. Data compilation | |||
Index Calculation For all NACE Rev. 2 activities, chained Laspeyres indexes are compiled. Weights The weights structure for each service and each enterprise is defined by the BtoB turnover information given by the enterprise itself. Each enterprise is turnover that declares in the questionnaire. Estimates for non-response Data for non-respondents are estimated by using data of the previous quarter. |
|||
18.6. Adjustment | |||
Seasonally adjusted indices are not calculated. |
