What does the survey cover?
The investment statistics describe annual investments in fixed assets by companies. Statistics Netherlands looks at the value of investments from various perspectives:
• the Standard Industrial Classification 1993 (SIC’93) of Statistics Netherlands
• fixed assets acquired in ownership (including financial lease) and investments through operational lease or hire
• type of asset
• new or used asset
The value of sold assets is also presented.
Economically active enterprises in SIC’93 sectors 014, 10-64, 70-74, 90 and 93 in the period under review.
Company. Statistics Netherlands defines a company as an actual participant in the process of the production of goods and/or provision of services, characterised by control over its production process and by the provision of its products and/or services to third parties.
A company is not necessarily equal to a legal entity (e.g. a limited or private company), but may consist of one or more legal entities which together constitute an autonomous entity in the production process.
Date/year survey started
The survey in its present form started in 1995. In the period 1995-1999 it collected data on realised investments according to the criterion of use (including operational lease and hire). From 2000 the investment data are based on the criterion of ownership (excluding operational lease and hire). Investments were also studied in the period 1949-1997, but the results are not comparable with those of the survey.
The investment data of year T have the following publication timetable:
• in the middle of year T+1, provisional investment data (total investments without specifications) of year T are published for three sectors, namely mineral extraction, manufacturing, and energy and water supply
• at the end of year T+1, the provisional investment data of year T for the three above-mentioned sectors are adjusted
• in the middle of year T+2, the definite data of year T for all sectors in the survey (including the three above-mentioned sectors) are published. The data for the three above-mentioned sectors are often published somewhat earlier than those for other sectors
Only when the definite data are published, do the specifications (SIC, region, type of asset, ownership/hire, new/used) become available for publication. Because of among other things the quality (reliability) of the data, breakdowns by SIC and by region are limited. In the table concerned, the selection of SIC and region is limited to those groups for which publication is actually possible.
How is the survey conducted?
Type of survey
The survey is a sample survey. On the basis of the SIC and company size, a stratified sample is drawn from the survey population. Companies with 20 employees or more are all included in the survey.
Respondents may submit the required data electronically or on paper.
The sample size varies strongly per sector of industry, as the number of companies also varies per sector. Overall, more than 60,000 companies are invited to participate in the survey, about 8 percent of companies in the Netherlands.
Checking and correction methods
Statistics Netherlands conducts plausibility, completeness and consistency checks on data received from companies.
Results are imputed for companies which do not respond or respond too late.
Received data are raised to the total number of companies in a sector in the period under review by means of a quotient estimator. To raise the response data to the entire population, an assistance variable is used that is known for the entire population, namely the number op persons employed. On basis of the response, the average investments per person employed are calculated. With this result the total investments for the rest of the population can be estimated.
Quality of the results
On basis of the confidence margins of the investments at the various SIC levels, a safe level of detail is determined. The same applies to the detail of region.
The methods used in the statistical processing of the sample data are aimed to guarantee comparability in time of the results.
In the statistical process, checking and correction methods and accuracy studies are applied, and the response is maximised.
