Industrial production output (110). The purpose of the survey is to provide data for the calculation of Short-Term Statistics (STS) indicators and for the National Accounts to estimate GDP. Industrial production output is published as an index. The index data are presented in the following forms:
Unadjusted;
Calendar adjusted;
Seasonally adjusted.
3.2. Classification system
NACE Rev. 2.
3.3. Coverage - sector
The survey covers sections B, C, D (Groups 35.1 and 35.2) of NACE Rev. 2.
During the reference year, the survey includes enterprises employing 20 or more persons in industrial production, as well as those employing fewer than 20 people, to ensure that the data compiled at the 2-digit division level of NACE Rev. 2 cover at least 80% of Business Structural Statistics turnover in 2022 .
3.4. Statistical concepts and definitions
Volume indices of industrial production measure changes in the volume of industrial output during the reference period compared to the base period. The data refer to production within the calendar month. Industrial production output includes the value of shipments, receipts from industrial work performed, changes in stocks of finished products and work in progress during the reference month, as well as the value of fixed assets produced on own account. The production index is based on the deflated production value.
3.5. Statistical unit
Observation unit - Kind of activity unit (KAU).
Reporting unit - Enterprise.
3.6. Statistical population
In 2024, the number of enterprises surveyed monthly was 1550, with these enterprises accounting for over 80% of the volume of industrial production.
Data are collected from economically active enterprises whose main or secondary activity, according to the Statistical Classification of Economic Activities (NACE Rev. 2), falls under Mining and Quarrying (Section B), Manufacturing (Section C), and Electricity, Gas, Steam, and Air Conditioning Supply (Section D), excluding Group 35.3 – "Steam and Air Conditioning Supply", and have employed 20 or more people in industrial production. The sample additionally includes enterprises employing fewer than 20 people, to ensure that the data compiled on Divisions of NACE Rev. 2 (data at 2-digit level) cover at least 80% of business structural statistics turnover in 2022. The population of surveyed enterprises may be revised during the reference year by adding new economically active enterprises (in line with the mentioned criteria), updating economic activity classifications based on revised respondent information, or incorporating the latest data from administrative sources.

12.3. Completeness
Statistics on industrial production index are available on a monthly basis in accordance with the requirements of Regulation No 2019/2152.
13.1. Accuracy - overall
Data are collected from economically active enterprises if their main or secondary activity in compliance with Statistical Classification of Economic Activities (NACE Rev.2) is Mining and quarrying (Section B), Manufacturing (Section C), Electricity, gas, steam and air conditioning (Section D) excluding group 35.3 - "Steam and air conditioning supply" and whose number of employees is 20 or more. The sample additionally includes enterprises employing fewer than 20 people, to ensure that the data compiled on Divisions of NACE Rev. 2 (data at 2-digit level) cover at least 80% of business structural statistics turnover in 2022.
The response rate is 95%. Accuracy of the first estimates is assessed by mean revision, which is 0.09 for all industry (sections B,C,D). Revisions of first estimates are made due to new responses, as with the last month of every quarter, data also from the previous two months are revised. Number of respondents surveyed by questionnaire is 1550. Population part that is cut off does not exceed 20% in the share of total industrial turnover.
The accuracy is tackled at national level, by eliminating inconsistencies and errors.
13.2. Sampling error
Sampling errors are not calculated for IPI indices.
13.3. Non-sampling error
Over-coverage errors:
There is a classification error in the unit frame, as some units accessible through the frame may not belong to the target population (for example, when an enterprise's activity has changed). This error does not exceed 1%. Changes in unit classification are detected as soon as possible, and the kind of activity is updated accordingly.
Data collection or access errors:
Data collection errors are minimized through data analysis (comparisons of industrial output with administrative data and clarification with respondents where needed).
Unit non-response rate is 5%, Item non-response rate is close to 0.
Editing, coding and imputation errors:
A small part of data is imputed (5%). The imputation is calculated using the enterprise's historical data, the growth rate of similar enterprises within the same NACE code, and expert judgment to determine the imputed value.
Modelling errors:
There are no models used for estimation.
The survey is compulsory. Data submission is available electronically (used by 98% of respondents) and via email (approximately 2%). Follow-up for missing responses begins after the 15th of the month, primarily through telephone contact. 34 days after the end of the reference month, when the first data is published, the response rate is approximately 95%. The response rate at the time of national publication and transmission to Eurostat remains consistent. Imputation is used to address non-response, based on previous submissions from the same enterprise and/or data from comparable enterprises.
14.1. Timeliness
Production index is published at 13:00 local time on the 34th day after the end of the reference month; if the 34th day is weekend or holiday, it is published on the next working day. Questionnaires are sent to the reporting unit at the end of the year for all months of the coming year, asking to give information on each reference month untll the 15th date of the following month. Data collection normally is closed 5 days before the publication.
14.2. Punctuality
The data is published according to the release calendar and sent to Eurostat at the same date when the press release is published in the Official statistics portal.
In 100% of cases, the data is published according to the schedule.
15.1. Comparability - geographical
Methods and definitions are comparable with the European ones and cover all national territory.
15.2. Comparability - over time
The Industrial Production Index, published on the Official Statistics Portal database, is available free of charge. The information includes monthly, quarterly, and annual data starting from the year 2000, in accordance with NACE Rev. 2 (down to the two-digit level). The data are comparable over time.
15.3. Coherence - cross domain
Comparisons are made with monthly industrial turnover, quarterly net turnover and PRODCOM data as well as annual SBS data. The main difference between STS data and annual SBS data are due to different size of sample and different unit of observation (enterprise for SBS and kind of activity unit for STS). PRODCOM and STS data also vary because of different sample size and collecting data by manufactured products. National Accounts use STS data for GDP calculation, mostly there is coherence between data, some differences can be due to different method of calculation.
15.4. Coherence - internal
Computation of lowest level indices: the lowest-level indices are obtained by firstly deflating the gross output data in current prices for each NACE class to the prices of the base year using the corresponding producer price index at 4-digit NACE level. The index is calculated monthly for both the year reviewed and the previous year. The higher level indices are derived by aggregating the basic indices using the value added at factor costs from the latest industrial structural survey as weights that are revised every year.
Aggregation: using base period weights, the lowest-level indices are progressively aggregated to the 3- and 2-digit NACE levels, MIGs, and the total index. Due to small differences between the total MIGs and the total index, the total index at the 2-digit NACE level is used for publication.
In 2024, the number of enterprises surveyed monthly was 1550 and their share in the total volume of industrial production exceeded 80% (from annual SBS data).
In Latvia, statistical questionnaires include a question about the time required for respondents to complete them. According to the results, the annual average response burden for the Industrial Production survey was 1.2 hours per respondent, totaling 1456.5 hours for all enterprises.
17.1. Data revision - policy
The CSB Revision Policy has been established in accordance with European Union and international recommendations and best practices.
CSB statistical data is revised in accordance with the scheduled revision cycle and plan.
Within the context of industry statistics, the revisions of statistical data concern:
Regular revisions of the published data, adding revised or more detailed information; revisions of the published data with the help of seasonal adjustment method.
Long-term planned revisions of the published data in accordance with the changes in methodology or classifications.
Unplanned revisions (correction of errors) are carried out, if a respondent updates, supplements or corrects data on any of the previous periods, or if the methodology changes.
The same revision policy is applied nationally and in transmissions to Eurostat.
17.2. Data revision - practice
Regular (routine) revisions of Industrial Production Index (non-adjusted data) are done every quarter, when publishing data on the last month of the quarter, the data of the previous two months are updated. Revision of sesonal adjusted data are done every month. Calendar adjusted figures, seasonally adjusted figures and trend figures are revised from January 2000 onwards every month. Regular revisions are quite small and usually do no affect totals. In databases metadata users are informed of regular revisions.
In 2024 for unadjusted data the Mean Absolute Revision (MAR) was 0.188 and the Mean Revision (MR) was 0.029, for calendar adjusted data MAR was 0.185 and MR was 0.022.
Long-term planned (major) revisions are conducted following amendments to legal acts, changes in the base year, or updates to classifications that require revisions.
If there are unplanned revisions (correction of errors), the data are corrected as soon as possible. Revised data have a note consisting of date and basic information of revision. Published indices may be revised if the corrections significantly affect the total industrial production index..
In case of changes in methodology or major changes in the data, the public will be informed in advance of the event.
Benchmarking is not used.
18.1. Source data
Data on the volume indices of industrial production are obtained with the help of enterprise survey, building a threshold sample. Data are collected from the CSB monthly survey "1-r "Survey of industrial activity"".
Data are collected from economically active enterprises if their main or secondary activity in compliance with the Statistical Classification of Economic Activities (NACE Rev.2) is Mining and quarrying (Section B), Manufacturing (Section C), Electricity, gas, steam and air conditioning (Section D) excluding group 35.3 - "Steam and air conditioning supply" and if 20 and more persons are employed in industrial production.
The sample additionally includes enterprises employing fewer than 20 people, to ensure that the data compiled on Divisions of NACE Rev. 2 (data at 2-digit level) cover at least 80% of business structural statistics turnover in 2022.
Product coverage: all production of the reporting unit is included in the index.
Classification: NACE Rev. 2 is used to classify enterprises by their economic activity. Reported production data are grouped into more than 160 classes based on the NACE Rev. 2 classification corresponding to each enterprise.
18.2. Frequency of data collection
Monthly.
18.3. Data collection
Data are collected with the monthly statistical questionnaire "1-r". Electronic questionnaires can be downloaded on the official website and completed online (98% are submitted this way). Questionnaires can also be submitted via e-mail. Non-responding units are followed up by telephone.
18.4. Data validation
CSB uses the Integrated Statistical Data Management System (ISDMS) as its main program for data entry and processing, which includes automatic control and validation tools. Standard MS Office professional software (MS Excel, MS Access) is used daily for the compilation of industrial statistics.
Data are compared with the previous period and the same period of the previous year.
If some data are missing, administrative data (VAT) from the State Revenue Service are used for imputation.
18.5. Data compilation
The Industrial Production Index (IPI) is calculated using a chain-linked method with the annual overlap technique. This calculation is based on the average monthly volume of products manufactured in the previous year (at constant prices). Weights are derived from the value added by enterprises two years prior, broken down by NACE sections, divisions, groups, and classes. The IPI is computed by adjusting production output indicators at constant prices using producer price indices. Weights are updated annually to reflect changes in the industrial structure. The average output volume from 2021 is used as the base for comparison.
18.6. Adjustment
The production value data are deflated with the producer price index of the corresponding NACE Rev.2 class.
Calendar and seasonal adjustment
A time series is a sequence of observations collected at regular time intervals, for example, a monthly time series. It characterises indicator changes or development thereof. Seasonality and calendar effects are present in a large number of economic time series.
Seasonality or seasonal fluctuations of time series mean those movements, which recur with similar intensity in the same season each year. For example, each year Christmas shopping time can be observed in time series reflecting retail sales statistics. Change of seasons, social habits and influence of institutional factors are among the main causes of seasonality.
The calendar effects cover influence of calendar on time series. It is impact left by differing number of working days (or Mondays, Tuesdays and other days of the week) in months on changes of indicator. For example, number of working days differing among the months may affect goods produced time series.
When the time series are influenced by seasonality or calendar effects, it may be difficult to get clear understanding on indicator changes over the time. Seasonal adjustment is made to eliminate seasonal fluctuations and calendar effects in time series.
As a result seasonally adjusted time series, from which seasonality and calendar effects have been removed, are produced. It means that seasonally adjusted time series provide an estimate for what is “new” in the series, for example turning points in trends, business cycle or irregular component. Moreover seasonal adjustment results in calendar adjusted time series, in which calendar effects or varying number of working days in months has been eliminated. Specifics of seasonally adjusted statistics allows improving data comparability over time:
Seasonally adjusted time series do not contain seasonal fluctuations and calendar effects, thus it is possible to compare, for example, data on the current month with the previous month's data.
Calendar adjusted time series are not influenced by calendar effects and are used to compare, for example, statistics on current month with the data on corresponding month of the previous year.
The seasonal adjustment is made taking into account seasonal adjustment guidelines developed by the European Statistical System.
Software - JDemetra+ 2.2.3.
Seasonal adjustment method - TRAMO/SEATS
Last model revision - For data of January 2024
It must be taken into account that in accordance with current seasonal adjustment methodology, when data on the new period are added, the data on previous period are recalculated; therefore information on previous periods in the adjusted time series may change each month.
There are no known economic outliers in the data.
Automatic outlier detection for the last year period using default critical value.
There is no consistency of different agregation levels, because time series are seasonally adjusted directly.
Industrial production output (110). The purpose of the survey is to provide data for the calculation of Short-Term Statistics (STS) indicators and for the National Accounts to estimate GDP. Industrial production output is published as an index. The index data are presented in the following forms:
Unadjusted;
Calendar adjusted;
Seasonally adjusted.
10 June 2025
Volume indices of industrial production measure changes in the volume of industrial output during the reference period compared to the base period. The data refer to production within the calendar month. Industrial production output includes the value of shipments, receipts from industrial work performed, changes in stocks of finished products and work in progress during the reference month, as well as the value of fixed assets produced on own account. The production index is based on the deflated production value.
Observation unit - Kind of activity unit (KAU).
Reporting unit - Enterprise.
In 2024, the number of enterprises surveyed monthly was 1550, with these enterprises accounting for over 80% of the volume of industrial production.
Data are collected from economically active enterprises whose main or secondary activity, according to the Statistical Classification of Economic Activities (NACE Rev. 2), falls under Mining and Quarrying (Section B), Manufacturing (Section C), and Electricity, Gas, Steam, and Air Conditioning Supply (Section D), excluding Group 35.3 – "Steam and Air Conditioning Supply", and have employed 20 or more people in industrial production. The sample additionally includes enterprises employing fewer than 20 people, to ensure that the data compiled on Divisions of NACE Rev. 2 (data at 2-digit level) cover at least 80% of business structural statistics turnover in 2022. The population of surveyed enterprises may be revised during the reference year by adding new economically active enterprises (in line with the mentioned criteria), updating economic activity classifications based on revised respondent information, or incorporating the latest data from administrative sources.
