The TSNI collects information on how and why people travel within Northern Ireland. The headline report is the first to be produced each year and contains key results. Due to significant changes to the survey methodology because of the COVID-19 pandemic, the 2020 survey estimates were reported as a single year instead of the usual three years combined. It was decided to continue to report data after the methodology change as a single year and therefore 2021 is also being reported as a single year in the headline report. Therefore 2020 and 2021 results can be compared with each other but are not directly comparable to those of previous years.
