Following the completion of the EU Single Market in January 1993 customs declarations, the traditional source of almost all trade statistics, are no longer required for most movements of goods within the EU. A new EU-wide system for collecting intra-EU trade statistics, Intrastat, was introduced on 1 January, 1993. This Intrastat survey is conducted by the Revenue Commissioners, while estimation, data analysis and publication is the responsibility of the Central Statistics Office. Trade with non-EU countries continues to be based on customs documents.
Prior to 1993, trade statistics were far more timely than most other economic statistics because traders had to complete customs documentation in order to ensure the speedy movement of goods, and this documentation provided the basis for compiling the trade statistics. The new Intrastat data collection system for EU trade has lost this advantage, and is subject to the non-response and timeliness difficulties normally encountered in direct statistical inquiries.
The timeliness of publication has improved in recent months. However, considerable efforts will be required to significantly reduce the existing time lag. Over the coming year, it is planned to reduce the publication delay by at least three days a month on average.
Ireland is not the only country experiencing publication delays. The changes introduced by the new Intrastat system are of such magnitude that all EU national administrations are confronted by major problems in the collection, compilation and analysis of their trade statistics.
