From OER the related tables seem to be:
The HZ_GEOGRPHIES table stores data representing physical geographies. For example, this table would be used to store United States as a geography with GEOGRAPHY_CODE as US and GEOGRAPHY_TYPE as COUNTRY
The HZ_GEO_HIERARCHY_CF table contains geography hierarchies in ten level of column-flattened structure.
There does not seem to be data for "sector" presumably its in some of the generic de-normalized columns ?
