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. In this respect, national statistical offices are expected to align with the European Statistical System (ESS) which refers to the partnership between Statistical Office of the EU (Eurostat) and the national statistical offices and aims to the production of comparable statitstics at the EU-level, on the subjects listed below:

• Producing comparable statistics for member states and candidate countries in terms of definition and methodology,
• Adopting EU standards related to definition, methodology, classification, publication frequency, etc. 
• Using coherent and comparable statistical data in the negotiation process. 

The acquis covers methodology, classifications and procedures for data collection in various areas such environment, health, economy, transport. No transposition into national legislation is needed as the majority of the acquis takes the form of regulations.
