10.6. Documentation on methodology
A short description of the methodology and sources used to compile the Producer Price indices in industry is available on the Official statistics portal: Producer Price index in industry
Management Systems of the Central Statistical Bureau (CSB) are certified according to requirements of the ISO 9001:2015 standard "Quality management systems – Requirements" and Information security management system
is certified to the ISO/IEC 27001:2022 standard “Information security, cybersecurity and privacy protection — Information security management systems — Requirements”.
The Quality Policy of CSB consists of the CSB's vision, mission, core values and commitment to meet the requirements, follow good practice and ensure continuous improvement.
The quality policy is designed and implemented in accordance with the CSB strategy and the action plan.
11.1. Quality assurance
The quality of statistics is assessed according to five quality dimensions: relevance, accuracy and reliability, timeliness and punctuality, availability and transparency, as well as coherence and comparability.
The quality indicators are calculated taking into account Eurostat defined methodology for the calculation of the Quality indicators.
11.2. Quality management - assessment
Once a month relevance, accuracy and reliability, timeliness and punctuality, comparability, coherence are recorded.
If a significant influence of corrections (more than 0.1 percentage point) is established upon applying corrected, revised or delayed information for calculations of the total price index within 12-months period (m/(m – 12)), the published producer price indices for the previous period shall be corrected.
12.1. Relevance - User Needs
The main users are: Bank of Latvia, Ministry of Economy, Eurostat, news agencies, internal users.
If a user needs some specific information, they may contact the CSB consultant with the request on information required (level of detail, base period, etc.) and CSB staff will provide a response.
12.2. Relevance - User Satisfaction
The index for user satisfaction isn't available, but there is a regular contact with the main users, in order to meet any specific information may be needed. There were no relevant complains on the PPI.
12.3. Completeness
Statistics on producer price indices in industry are available on a monthly basis and in accordance with legal requirements.
13.1. Accuracy - overall
The accuracy is tackled at national level, by eliminating inconsistencies and errors.
Data collection is based on cut-off sample and the sample is updated annually. At the end of the year CSB together with enterprises choose the most popular products (according to PRODCOM) for the next year of the data collection.
Data are collected by web questionnaires, using the data validation rules. The data also are checked manually by statisticians and all questionable cases are verified.
The published data are final, no first estimation is made (see also 17.1).
13.2. Sampling error
Sampling errors are not calculated for PPI because the sample is based on the cut-off method. Confidence intervals or CV are not calculated for PPI.
Target sampling is made from economically active enterprises if their main or secondary activity in compliance with NACE Rev. 2 is Section B, C, D or E and the number of employees in the enterprise is 20 or more, or net turnover in the preceding year exceeding 430 thousand euro. Enterprises with as large as possible share of product sales in the respective industrial activity (NACE Rev. 2 class) are included in the sample. Products are chosen with high sales volume in the domestic or non-domestic markets or both according to the PRODCOM. Enterprises are chosen with a record of stable production and sales activity and a large share of sold production on the domestic and non-domestic markets. The list of enterprises involved in price recording is reviewed every year and enterprises with unstable production operations are excluded, while enterprises playing a significant role in the respective industrial activity - are included in the sample.
In 2025 data for STS were based on 651 enterprises. Approximately 2.4 thsd individual prices were observed; of which around 1.3 thsd prices were recorded for the production sold on the domestic market and around 1.1 thsd prices for exported goods, e.g. 3.8 observations per respondent for total index.
13.3. Non-sampling error
The types of non-sampling errors are not relevant:
coverage errors
enterprises with as large as possible share of product sales in the respective industrial activity (NACE Rev. 2 class) are included in the sample
data collection errors
the unweighted response rate is around 97.8%. Telephone contacts or electronic reminders are used to follow up missing responses
unit non-response (missing data)
the unweighted response rate is around 97.8%. Telephone contacts or electronic reminders are used to follow up missing responses. If enterprise stops their work, then CSB staff analyses every situation and the best method for missing data are chosen, see next point – item non-response
the published data are final, no first and later estimation are made
item non-response (missing data)
in case of a missing price, the previous observed price is carried forward or imputed using the index for similar products of class to which the product belongs. If a product becomes permanently unavailable within the year, an appropriate replacement is selected close to the previous variety
data processing errors
the CSB has Integrated Statistical data management system - the tool for data entering, processing with automatic control and validation
standard MS Office professional software (MS Excel) is used daily for additional validation. The Producer Price Index calculation system provides automated index calculation, storage, production of the necessary data according to the requirements of external and internal data users. The system includes processes such as data loading, validation, weight calculation. Double checks and error listings are used to avoid processing errors
model errors
models are not used in PPI.
No serious mistakes have been detected in the published data.
Size-weighted unit response rate is not calculated.
14.1. Timeliness
The information on producer price indices in industry (PPI) is published at 13:00 o’clock of local time on the 15th working day of the month following the end of the reference month.
The information letters about questionnaires for the next year are sent to respondents at the end of the year.
The deadline for replies to questionnaires varies depending on the activity and it could be the 20th day in reference month, 10th or 15th day after the end of each reference month. The data collection normally is closed 3 to 5 days before the publication.
14.2. Punctuality
The data were published according to the release calendar and sent to Eurostat at the same date when published press release on Official statistics portal.
Data published according to schedule 100%.
15.1. Comparability - geographical
Producer prices in industry are collected across the country so that index represents the country as a whole.
15.2. Comparability - over time
The monthly and annual data of total industry according to the NACE Rev. 2 down to two-digit level are available from 2000 and onwards.
15.3. Coherence - cross domain
The PPI weights are derived from the same data sources as the national accounts production accounts. The national accounts use the PPI to deflate the output of appropriate industries. No comparison with other data sets is available.
15.4. Coherence - internal
There were no any internal data inconsistencies recognised.
The annual average burden was 4 hours per respondent or totally 2449 hours for all PPI (nationally) enterprises in 2025. The CSB total time use for national PPI was 5051 hours per year (it is impossible to distinguish separately costs for the STS or other Eurostat needs).
17.1. Data revision - policy
CSB Revision Policy has been elaborated in accordance with the European Union and international recommendations and good practice.
The same revision policy is applied to STS data released nationally and transmitted to Eurostat.
Within the context of price statistics revisions of statistical data concern the published producer price indices may be revised in case an error is found in the calculations, or a respondent has submitted updated information for the previous period, which significantly – by more than 0.1 percentage point affects the total price index for the 12 months (m/(m - 12)).
Calculation errors affecting the result to one decimal place are corrected and the following index revisions shall be implemented immediately. The corrected price indices are published together with the data for the next reporting period with an indication to the correction.
17.2. Data revision - practice
Revisions are announced simultaneously with the revised data. Major changes in methodology are announced on the Official statistics portal at the time the data compiled using the revised methodology are first published. The Mean Revision (MR) between 2023 and 2025 (36 months) for NACE aggregate B to E36 (total) was - 0.10. The Mean Absolute Revision (MAR) between 2023 and 2025 (36 months) for NACE aggregate B to E36 (total) was 0.19. Benchmarking is not used.
18.1. Source data
Direct statistical survey of the target sample from the selected enterprises and products, as well tariffs on selected services and enterprises approved by the Public Utilities Commission.
In 2025, 651 enterprises were included in the STS sample and approximately 2.4 thsd individual prices were observed; of which around 1.3 thsd prices were recorded for the production sold on the domestic market and around 1.1 thsd prices for exported goods. Products are chosen with high sales volume in the domestic or non-domestic markets or both. Enterprises are chosen with a record of stable production and sales activity and a large share of sold production on the domestic and non-domestic markets.
The sample is updated annually.
18.2. Frequency of data collection
Data are collected monthly.
18.3. Data collection
Questionnaire No 1-RC (monthly) "Survey on producer prices in industry" is used for data collection with a pre-printed list of selected products for which prices are to be given.
The electronic reporting system is the main data collection tool (99.6%); e-mail questionnaire (0.4%) are used in data collection.
Data on producer prices assured by statisticians from Short-term Statistics Data Collection and Processing Section, they also perform data pre-treatment. For non-response are used telephone and e-mail contacts.
18.4. Data validation
The CSB has Integrated Statistical data management system - the tool for data entering, processing with automatic control and validation.
Standard MS Office professional software (MS Excel) is used daily for validation of producer prices in industry.
The Producer Price Index calculation system provides automated index calculation. The system includes processes such as data loading, validation, weight calculation.
18.5. Data compilation
In case of non-response - the imputation methods have been applied.
Individual product indices are combined using Laspeyres type formula and base period weights to obtain higher level indices by NACE Rev. 2 classes, groups, divisions and sections. All representative items have product weights at the lowest level of aggregation. The application of quality adjustment methods is limited. New enterprises are introduced at the beginning of the new reference year, but new representative products may be introduced although in the beginning of the new reference year and during the year (if the sample product is obsolete). For the replacement of selected products, the overlap method is used.
The weights are produced once a year - starting calculations for the first month of the reference year.
The weights refer to the value of production sold two years before the reporting period. Prices of December of the previous year serve as a base for price comparisons. The producer price indices in industry weighting system and base prices are updated annually. In order to ensure the symmetry of weight and price base periods, the weights applied to the calculation of producer price indices in industry for 2025 have been recalculated into the prices of December 2024.
18.6. Adjustment
The producer price indices in industry are neither seasonally nor working day adjusted.
Not applicable.
