Data Availability

Data availability for each catalog is displayed in a table with countries in rows and years in columns. There may be several rows for a given country, due to information being available through several nomenclatures and/or versions. For example, for Albania, trade is available in both HS and SITC in their different revisions (HS versions H0, H1, H2, and H3 and SITC versions S1, S2, S3 and S4). Therefore, there are eight rows of data for Albania. Each country generally reports trade information to UNSD using a single nomenclature/version. UNSD converts the reported information in all previous nomenclatures/versions. Watch the video below on "Data Availability" in WITS.
