The IST covers specific subject areas identified during a review of manuals, policies, publications and other information resources from various departmental organizations.
CICRED merged the word lists of Population multilingual thesaurus, Popline thesaurus and Multilingual demographic dictionary.
The thesaurus was initially based on the UNESCO Thesaurus (ISBN: 92-3-101469-2) and is continuously expanded and updated by the UK Data Archive. HASSET may be used by other organisations, for example to index materials, provided it is for non-commercial purposes and appropriate acknowledgement is given. A licence form allowing you to use or adapt HASSET in your own organisation can be requested from firstname.lastname@example.org.
