Monthly.

With effect from the January 2018 release, the CSO has re-introduced a monthly series for the main categories, replacing the previous three month rolling series. Monthly data from January 2016 is provided.

Scope

Overseas Travel.

Coverage

This release covers Overseas Travel into and out of the Republic of Ireland, however travel by residents of Northern Ireland into or out of the Republic of Ireland or domestic travel within the Republic of Ireland is excluded.

Data Collection

Data from the Country of Residence Survey (CRS) is used in this release.  This survey is conducted at Dublin, Cork, Shannon, Knock and Kerry airports and Rosslare, Ringaskiddy and Dublin seaports.  Residency data is collected from passengers by a Central Statistics Office (CSO) interviewer.  Surveys are also conducted on behalf of the CSO at Holyhead Port by the UK's Office of National Statistics.

Sample Design

A sample of flights and sailings is selected to facilitate proper representation of airport/seaport pairings, day, night, week day and weekend flights/sailings.

On the selected flights/sailings for the CRS, a 1 in 5 (20%) systematic sample of passengers is selected and their country of residence is recorded.

Sample results are grossed to total passenger numbers travelling for each airport or seaport pairing, as provided by the airports and ferry companies.

Where there is no survey coverage in a period for an airport/seaport pairing, results are imputed using the 'nearest neighbour' imputation methodology.

Sample Size

The sample size for the Overseas Travel release in respect of December 2018 was just below 31,500 passengers.

Seasonal Adjustment

Seasonally adjusted monthly data is available in Table 8.  Trip numbers are subject to a high degree of seasonality.  These seasonal fluctuations do not affect annual comparisons but they do affect monthly or quarterly comparisons.  Typically trips are at their highest during the summer months, although there are also clear peaks around Christmas and Easter.  To facilitate interpretation of underlying trends, trip numbers are adjusted to remove these seasonal trends.  Seasonal adjustment is conducted using the direct seasonal adjustment approach.  Under this approach each individual series is independently adjusted each month, e.g. aggregate series are adjusted without reference to the component series.  Seasonal adjustment models are developed for each series based on unadjusted data from January 2000 to the current period.  These models are then applied to the entire series.  Seasonal factors are updated each month. 

The adjustments are completed by applying the X-12-ARIMA model, developed by the U.S. Census Bureau to the unadjusted data.  This methodology estimates seasonal factors while also taking into consideration factors that impact on the quality of the seasonal adjustment such as:

  • Calendar effects, e.g. the timing of Easter (see definition (5)).
  • Outliers, temporary changes and level shifts in the series.

Rounding

Individual figures have been rounded independently and the sum of the component items may therefore not necessarily add to the totals shown.

Reliability of Results 

Estimation of survey results using the above sampling design introduces a statistical variability which would not be present if all passengers from every flight/sailing had been sampled.  This means that the survey results are best estimates based on the information collected for the sample.

Airport Pairings

The CSO "Airport Pairings" database contains information on every direct flight in and out of the nine Irish airports on a monthly basis.  The most recent monthly passenger figures will be added to the database two months after the end of the reference month.  For details please go to http://tinyurl.com/2nypw8

Definitions

(1) Trips

The data presented in this report is in terms of trip numbers.  A trip is defined as a journey (usually including the return) from one place to another.

(2) Visitor

The definition of Visitor used in these surveys is based on that agreed with Eurostat, the European Statistical Office.  A Visitor is defined as 'any person travelling to a place other than that of his/her usual environment for less than twelve months and whose main purpose is other than the exercise of an activity remunerated from within the place visited'.  However, as the CRS does not establish the reason for an individual's trip or length of stay, those travelling for reason of remuneration or for more than one year to a country cannot be excluded.  Therefore, trips may include those travelling for paid work.  Commercial Drivers travelling on sea routes are excluded.

(3) Country of Residence

Country of Residence is defined as the country in which the person has resided during the past year.

(4) Transit/Transfer Passengers

Transit passengers are defined as those who make a stop at an airport without any particular purpose other than being en route to another destination.  These passengers generally do not disembark from their aircraft and are not covered by the Country of Residence Survey.

Transfer passengers or 'connecting passengers' are also defined as those who make a stop at an airport without any particular purpose other than being en route to another destination.  However, unlike transits, transfer passengers disembark the aircraft and pass through the airport en route to their connecting flight.  The two flights must be booked on the same ticket for it to be considered a transfer.  Such passengers are included in the estimates of trips for Overseas Travel release and are treated in the same manner as same-day visits.  This is in line with UNWTO (United Nations World Tourism Organisation) International Recommendations on Tourism Statistics.  Transfers are surveyed for the Country of Residence Survey.

A transfer trip is a completed journey – for example a passenger who travels from London Gatwick to Dublin Airport and then on to New York (on the one ticket) is counted as two transfer passengers and one transfer trip.

In 2018, the number of overseas trips to Ireland increased by 6.9% when compared with 2017. Excluding transfer trips, the annual increase in overseas trips to Ireland would have been 5.9%. 

In 2017, the number of overseas trips to Ireland increased by 3.6% when compared with 2016. Excluding transfer trips, the annual increase in overseas trips to Ireland would have been 1.6%.

(5) Timing of Easter

Easter falls each year on a Sunday between March 22nd and April 25th, inclusively.  In 2018 Easter Sunday fell on April 1st, while in 2017 it fell on April 16th.  Trip numbers each year are greatly influenced by when Easter falls.
