The Cross Border Shopping survey was included in the General Household Survey (GHS) in the first quarter (January to March) of 2018. One member of each household answered questions on behalf of the household about travel to Northern Ireland in the previous 12 months and specifically about shopping in Northern Ireland. The questions on shopping in Northern Ireland focused on how much households spent and the frequency of shopping trips. Online purchases are not included.
The total expenditure on shopping was broken down into seven categories – Alcohol, Cosmetics, Food and groceries (including tobacco), Medicine, Clothes, footwearand sports goods, Petrol/diesel and Other.
