The Central Statistics Office (CSO) has today (Wednesday 10th August) published Household Travel Survey data, which shows that Irish residents took almost 2.1 million domestic trips and over 1.5 million outbound trips in Quarter 1 2016.

The purpose of the Household Travel Survey (HTS) is to measure domestic and outbound travel patterns involving overnight stays and associated details (expenditure, purpose of trip, type of accommodation used etc.) of Irish residents.

Today’s data is based on an improved methodology which provides more accurate estimates of the number of domestic and outbound trips. Commenting on the rationale for the methodological change which has been applied retrospectively back to Quarter 1 2012, Patsy King, Statistician, Tourism and Travel Section, CSO says:

“Analysis of the data showed that more older people were completing the HTS questionnaire and that younger age categories were under-represented. As a consequence, the CSO decided to review how the results are weighted by age group.

The new methodological change introduces a weighting system which is based on the CSO’s Quarterly National Household Survey (QNHS) population data, broken down by sex, age group and region.

Significantly, the revisions demonstrate that in fact about 20% more domestic trips are taken each year than was previously estimated. The new methodological changes, however, have a minimal effect on the estimate of outbound trips, which are calibrated to international passenger data.”
