The development in industrial production, published each month by Statistics Netherlands, is one of the most significant economic indicators. This development is commonly presented as a value added quantity index (production index) which refers to a particular base year. The value added of goods and services is the value of produced goods and services minus the value of raw and auxiliary materials, semi manufactured products and services necessary to produce them. Every month Statistics Netherlands also publishes sales indices, subdivided into domestic and exports, of industrial companies. The sales indices of industrial companies are calculated comparing the sales from all industrial companies with at least twenty employees in the month under inquiry with the sales in the average month in the base year 2000. Additionally Statistics Netherlands publishes monthly indices on the value of received orders, subdivided into domestic and foreign orders. All the above indices aim to provide information on the economic process in industry, shortly after the end of the month under review.
At company level, the volume developments of production and sales are divided into the sections mining and quarrying, manufacturing industry and public utilities. These three sections together make up industry. Usually, industry also includes construction. This branch of industry, however, is not included in the production index, nor in the sales index of industry. The manufacturing industry is divided into divisions, groups and classes based on the Standard Industrial Classification of all Economic Activities (SIC) 1993 of Statistics Netherlands; in this classification, companies are classified according to main production activity.
Ideally, the determination of production volume developments would require monthly data on the production of goods and services and the use of raw and auxiliary materials of all companies. In practice, the number of interviewed companies as well as the number of respondents are limited. For each group of industry, an indicator is selected which most truthfully reflects the development of the gross value added at basic prices. Turnover is the most significant indicator of the production index, if possible in combination with stock data. Producer price index figures are essential for the calculation of volume developments. Other indicators are real production and/or consumption data and hours worked. If monthly data on a particular group of industry are not available, whereas, for instance, quarterly data are, the latter will be converted to monthly data. Statistics Netherlands calculates the production index as a chain index. The monthly volume development of a particular year is calculated on the basis of the average of the previous year. Next, the index is calculated by linking these developments to the base year 2000. The most recent indices for production are provisional. Due to more response of companies the indices can change.
The volume index figures of production in the various categories, industry groups and classes are weighted by the gross value added at basic prices from the National Accounts. In the National Accounts macro economic data are consistently integrated. The weighting coefficients used in a specific year, are based on the previous year of the most recent National Accounts.
The aim of the production index is to measure the volume change of the gross value added at basic prices. This can often not be measured directly because short-term information on value added is lacking. Verification of the production index is therefore necessary. In the compilation of the National Accounts annual input-output tables are drawn up in real prices and in basic prices. The latter tables can be compared with the results of the production index.
Differences between the production index and the gross value added at basic prices may occur for the following reasons:
It will be clear from the above that differences may arise between the development of production within the scope of the production index and annual calculations of National Accounts. Therefore, the production index is adjusted annually to the three most recent years of National Accounts available. Figures referring to the year t-3 are considered permanent because all the available information has been incorporated. Figures referring to the years t-2 and t-1 are provisional, since not all information is available in detail.
After the publication of final results CBS only updates the results if there are major revisions / corrections are necessary.
