Descriptions for the different hierarchies of the COICOP codes can be obtained by merging the COICOP file with the expenditure/income file using the COICOP code as the common variable.
The COICOP file also indicates the reference period for which expenditure on a particular item was collected (e.g. 1 month, 11 months or 12 months), section number in the main questionnaire in which the
question/item was asked as well as the instrument used to obtain the data (diary or main questionnaire)
