While this publication provides information on tourists from outside of NI, NISRA does not have direct responsibility for the collection of all such information, some of which is provided from organisations in the RoI.

The value and volume of overseas visitors to Northern Ireland (NI) who exited through a NI port is measured using the NI Passenger Survey (NIPS).

From 2010, the administration of the survey has been carried out by the Northern Ireland Statistics & Research Agency, Central Survey Unit. 

Detailed methodology can be found at the link below:

Information on GB and all other overseas visitors arriving via RoI ports and terminals is provided by Failte Ireland. Information on RoI visitors is provided by Central Statistics Office in the RoI.

These three sources are combined to estimate the number of external  overnight trips to NI.
