The Travel Survey for Northern Ireland is required to provide a comprehensive picture of personal travel behaviour by people living in private households in Northern Ireland.  The sample is therefore designed to provide a representative sample of households in Northern Ireland. 

The sample for the Travel Survey consists of a systematic random sample of 1,920 addresses selected from the NISRA Address Register (NAR). The NAR is developed within NISRA and is primarily based on the Land & Property Services (LPS) POINTER database. 

A total of 160 addresses are selected for interview each month for the Travel Survey. Each member of each household is asked to provide information about journeys made in a pre-selected seven-day period, known as the Travel Week. 

The information for the survey is collected in the following stages:

  • A placement call where members of the household are asked a series of questions about household composition, type of vehicles, travel habits and use of public transport. 
  • A travel diary is left with each respondent to be completed during a selected "travel week".
  • Finally a pick-up call - our interviewer will then call at the address to pick up the completed diaries.


A copy of the questionnaire can be viewed on the Travel Survey documents webpage.

Household information Availability of public transport
