What is the ESRA (EUROCONTROL Statistical Reference Area) ?
The EUROCONTROL Statistical Reference Area (ESRA), is designed to include as much as possible of the ECAC area for which data are available from a range of sources within the Agency (CRCO, CFMU and STATFOR) sources. It is used for high-level reports from the Agency, when referring to ‘total Europe’. The ESRA will change only slowly with time; a region will be added to the ESRA only when there is a full year’s data from all sources, so that growth calculations are possible. The current ESRA is really ‘ESRA 2008’. The regions of ‘ESRA 2008’ are illustrated in this map.
