Imports and exports
Imports and exports broken down by province are calculated as follows: Wherever possible, international trade is linked to companies operating from the Netherlands. If a company has one subsidiary, international trade of this company is attributed to the region where the subsidiary is based. If a company has more than one subsidiary, imports and exports are attributed in proportion to the number of staff employed in the various subsidiaries and provinces. It is not possible to link all foreign trade to companies at the regional level.
