Data collection

Data is collected using a spreadsheet which is uploaded to the IDEP reporting system.

Data validation

An overall error detection is performed based on fluctuations in foreign trade at product or country level. Specific companies are reconnected and answers are compared with previous answers.

Data compilation

The survey is a total census without weighting or correction for unit non response. There is only a small amount of imputation, for example, if quantities are missing. The validated data is grouped and tabulated in relation to product and country groups.

Adjustment

No correction of data is made except what has already been described under data validation and data processing.
