Industrial turnover (120):

— Industrial domestic turnover (121)

— Industrial non-domestic turnover (122)

Starting with 2014 non-domestic indicator is published in the following breakdown: turnover to euro area countries (122z) and turnover to non-euro area countries (122x). 

The purpose of the survey is to provide data for the calculation of STS. The aim of the turnover indicator is to show the development of turnover in value, and data is collected specifically for the domestic market and for the non-domestic market.

NACE Rev. 2.

The survey covers sections B, C of NACE Rev. 2.

During the reference year, the survey covers enterprises where 20 or 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 2021.

The objective of the turnover index is to show the development of the market for goods and services. Turnover comprises the totals invoiced by the observation unit during the reference period, and this corresponds to market sales of goods or services supplied to third parties.

Data refers to turnover during the calendar month

On a monthly basis the following main variables are collected:

•  total turnover (excluding VAT and excise taxes);
•  domestic turnover;
•  non domestic turnover;

Observation unit - Kind of activity unit (KAU)

Reporting unit - Enterprise

In 2023, number of enterprises surveyed monthly – 1521, the share of enterprises in the volume of industrial production exceeded 80%.

Data for Industrial Turnover Index are collected from economically active enterprises if their main or secondary activity is industry, Section B (Mining and quarrying) and C (Manufacturing) in compliance with Statistical Classification of Economic Activities (NACE Rev.2), 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 2021.

Only industrial production produced in territory of Latvia is included in the data.

Time series for this indicator according to NACE Rev. 2 is available starting from 2000.

2015 = 100

Not available.

Data are sent to Eurostat and information on industrial turnover is available on the homepage of Statistical Office of the European Union (EUROSTAT): http://ec.europa.eu/eurostat/data/database

A short description of the methodology is available on the website of the Official statistics portal: https://stat.gov.lv/en/metadata/5723-industrial-turnover-index

The CSB of Latvia has established a quality framework based on Operational Strategy of the CSB, mid-term Strategic Goals in Quality in Statistics and Action Plan of implementation of strategic goals in quality in statistics. Monitoring of Action Plan is performed monthly.
The CSB in its actions takes into consideration the European Statistics Code of Practice, the Fundamental Principles of Official Statistics of United Nations and ESS Quality Declaration as well as other related legal acts.

Metadata is prepared each month and disseminated on the Official statistics portal. 

The quality of statistics is assessed according to five quality criteria: relevance, accuracy, timeliness and punctuality, accessibility and clarity, coherence and comparability.
The quality indicators are calculated taking into account Eurostat methodology for the calculation of Quality indicators and documented into Project's Documentation System.

Every month the following indicators for quality monitoring and assurance are calculated: fields of relevance, accuracy and reliability, timeliness and punctuality, comparability, coherence are completed.

Data on industrial turnover index for users are available on the Official statistics portal database. Data are updated every month. The main users are: Eurostat, Bank of Latvia, European Central Bank, International Monetary Fund, Ministry of Finance, Ministry of Economy, Quarterly National Account Section of Macroeconomic Statistics Department (internal user).

We don’t receive any special feedback from our users and no user satisfaction survey has been done for this statistics. Official Statistics Portal data flow is monitored

Statistics on industrial turnover index is available on a monthly basis in accordance with the requirements of Regulation No 2019/2152.

The accuracy is tackled at national level, by eliminating inconsistencies and errors. 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) 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 2021.

The response rate is 95%.

Sampling errors are not calculated for Turnover indices.

Over-coverage errors:

There is error in unit classification, because some units accessible via frame do not belong to the target population (in the case, when activity of enterprise has changed). This error not exceeds 1 %. The change of unit classification is cathed as soon as possible and the kind of activity is changed.

Data collection or access errors:

Data collection errors are minimised by data analysis (comparing industrial turnover with other data admin data and clarification of data).

Item non-response is 5 %.

Editing, coding and imputation errors:

As the small part of data is imputed (only 5 %) and imputation is made by using historical data of enterprise, the growth rate of similar enterprises in the same NACE code and the imputed value is chosen by expert judgement.

Modelling errors:

There are not models used for estimation.

The survey is compulsory. 34 days after the end of the reference month, when the first data are published, the response rate is close to 100%. Telephone contacts are used to follow-up the missing responses after the 15th date of the month. Data can be submitted electronically (used by 98% of respondents) and by e-mail (about 2%). At the time when data are provided to Eurostat and published nationally, the response rate is the same. Monthly non-response rate for the industrial turnover index is under 5 % in the establishments included in the calculation, i.e., response rate comprises 95%. Imputation is used to compensate the non-response; this is made by means of previous replies and/or the replies of other businesses.

Turnover index is published at 13:00 o’clock of 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 till the 15th date of the following month. Data collection normally is closed 5 days before the publication.

The data were published according to the release calendar and sent to Eurostat at the same date when published press release in Official statistics portal.

In 100% of cases data are published in line with the schedule.

Methods and definitions are comparable with the European ones and covers all national territory.

Industrial Turnover Index published on the Official statistics portal database is available free of charge; information includes monthly data starting from 2000 and onwards and according to the NACE Rev. 2 (down to two-digit level). Data are comparable over time.

Comparisons are made with monthly industrial production. Turnover value data is in coherance with SBS, PRODCOM surveys. 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. 

Aggregation: using base period weights, the lowest-level indices are progressively aggregated to 3- and 2-digit NACE levels, MIGs and total index.

In 2022, the number of enterprises surveyed monthly comprised 1 529 and their share in the total volume of industrial production exceeded 80%.

In Latvia, statistical questionnaires contain a question about the time necessary for respondents to fill in the questionnaire. According to the results, the annual average burden in hours worked is 2.3 hours per respondent or totally 2852.0 hours for all enterprises. 

CSB Revision policy has been lain down in accordance with the European Union and international recommendations and good practice.

Basically, the CSB statistical data are revised in accordance with the scheduled revision cycle and plan.

Within the context of industry statistics routine 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 revision (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.

Vintage database has not introduced.

Revision policy is available on the CSB website: https://www.csp.gov.lv/en/media/5105/download?attachment

The same revision policy is applied nationally and in transmissions to Eurostat.

Regular (routine) revisions of Industrial Turnover Index (non-adjusted data) are done every quarter, when publishing data on the last month of the quarter, the data of previous two months are updated. Revision of sesonal adjausted 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. 

Long-term planned (major) revisions are conducted after amendments in legal acts, due to changes in the base year and classifications entail revisions. 

If there are unplanned revisions (correction of errors), the data are corrected as soon as possible and revised data have note consisting date and basic information of revision. Published indices may be revised if the corrections made to the calculations have significant influence on the total industrial turnover 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.

Data on industrial turnover are obtained with the help of enterprise survey, building a threshold sample. Data are collected from the CSB monthly report "1-r "Survey of industrial activity"".

Information on industrial turnover during the reference period at current prices is collected each month until the 25^th date, according to the classes of Statistical Classification of Economic Activities NACE Rev. 2.

Monthly

Data for Industrial Turnover Index are collected from economically active enterprises if their main or secondary activity is industry, Section B (Mining and quarrying) and C (Manufacturing) in compliance with Statistical Classification of Economic Activities (NACE Rev.2), 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 2021.

CSB has the main program used for data entry, processing with automatic control and validation tools - ISDMS (Integrated Statistical Data Management System).
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.

Industrial Turnover Index is nondeflated index and calculation thereof includes Section B (Mining and quarrying) and Section C (Manufacturing). Weights are industrial turnover of 2015 in breakdown – domestic market and export. Base used for the comparisons is average monthly turnover of 2015.

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.

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.
