Data are generally provided directly from the National Statistical Offices being compiled from sample surveys. Exceptions are noted in country metadata.
The data are generally available from sources every month. Exceptions (reported on a quarterly basis) are noted in country metadata.
This information is available at country level. Methodological information by country is also available from the IMF at: http://dsbb.imf.org/Applications/web/sddshome
Unit of measure used
Data are expressed as indices with average for a reference year equal to 100.
Depending on countries and sectors, production can be measured from deflated turnover or sales, value added, physical output, raw material inputs, hours worked or other employment data.
Sample generally includes all units whose employments are above or equal to a certain threshold. Some country applies random sampling under this threshold.
Data refer to the whole period (i.e. whole month or quarter).
OECD reference period is 2005.
OECD countries currently utilise one or a combinations of four statistical units (i.e. enterprise, kind-of-activity unit, local unit and establishment). Specific information is noted in country metadata.
The whole legal territory of the country is generally covered. Exceptions are noted in country metadata.
Production indices are available by industrial sectors and by types of goods. The Index for Total industry covers sectors corresponding to B (Mining), C (Manufacturing) and D&E (Electricity, gas and water) of the ISIC Rev. 4 or NACE Rev. 2 classification. For some countries, the Index for Total industry including Construction (Category F) is also presented. Services sector refers to categories G to S.
Information under 'Production' broadly applies to production indices by economic activities and by type of goods. It may not be relevant for indicators relating to commodity output or to the rate of capacity utilisation for which more specific information is available below or in specific country metadata.
Small units in size of employment are generally excluded unless combined output of these units' activities represents a significant portion of the total production.
Key statistical concept
Industrial production refers to the volume of output generated by production units classified under the industrial sectors, i.e. B, C, D and E of the International Standard Industrial Classification of all Economic Activities (ISIC Rev. 4). Data are generally presented in indices of industrial production, which measure volume changes of output, as well as in physical volume or in a ratio. Specific information is available in country metadata.
International Standard Industrial Classification of all Economic Activities (ISIC Rev. 4). In the case of European countries, NACE Rev. 2, derived from ISIC Rev.4, is to be used, in general, as reference for statistics referring to economic activities performed as from 1 January 2008 onwards. Exceptions are noted in country metadata.
Aggregation and consolidation
Several Steps are generally involved in the aggregation process of the Index of Industrial Production. Initially, partial indices for production groups at a low level of the Industrial classification are calculated from the production of each group's representatives using weights determined by the representatives' gross output. These partial indices are then further aggregated.
Weights used to aggregate data at branch and product level are based on variables measuring the relative shares of the products and branches in the value added of industry, in the base year. Specific information on weights used by countries is noted in country metadata.
The main seasonal adjustment methods used across OECD countries are X12-ARIMA and TRAMO-SEATS. Specific information is noted in country metadata.
Annual and quarterly data are generally the average of monthly data. Exceptions are noted in country metadata.
|Subject: Production > Industry (C, D and E) > Rate of capacity utilisation||.PRINCU.......|
The manufacturing sector is generally covered. Exceptions are noted in country metadata.
Key statistical concept
The rate of capacity utilisation is the ratio between the actual output and the maximum that could be produced with existing plant and equipment.

International Iron and Steel Institute (IISI)
Key statistical concept
Data measure the physical volume of the monthly output of crude steel. Total crude steel production is defined as the total output of usable ingots, continuously-cast semi-finished products, and liquid steel for castings. Exceptions are noted in country metadata.
|Subject: Production > Manufacturing > Investment goods > Total||.PRMNVG01.......|
Capital or investment goods are defined as goods, other than material inputs and fuel, used for the production of other goods and/or services. They include factory buildings, machinery, locomotives, lorries and tractors. Land is not usually regarded as a capital good.
