The acquis in the field of statistics requires the existence of a statistical infrastructure based on principles such as impartiality, reliability, transparency, confidentiality of individual data and dissemination of official statistics. National statistical institutes act as reference and anchor points for the methodology, production and dissemination of statistical information. The acquis covers methodology, classifications and procedures for data collection in various areas such as macro-economic and price statistics, demographic and social statistics, regional statistics, and statistics on business, transport, external trade, agriculture, environment, and science and technology. No transposition into national legislation is needed as the majority of the acquis takes the form of regulations.
