Travel Trends is an annual publication which presents some of the key trends in overseas travel and tourism drawn from the findings of the International Passenger Survey (IPS). Analysis is based on completed visits (for any purpose) of less than 12 months’ duration by:
a) overseas residents to the UK, and
b) UK residents abroad

What is the International Passenger Survey?
The IPS is a continuous survey carried out by the Office for National Statistics (ONS), the results of which are used by a number of government departments and organisations. The results are based on face-to-face interviews with a random sample of passengers as they enter or leave the UK by the principal air, sea and tunnel routes.
