In 5.5, the word "units" should be replaced with "statistical units", and the word new inserted before the first occurance of the word "variabl", as below:-
5.5. Derive new variables and statistical units
This sub-process derives data for new variables and statistical units that are not explicitly provided in the collection, but are needed to deliver the required outputs. It derives new variables by applying arithmetic formulae to one or more of the variables that are already present in the dataset, or applying different model assumptions. This activity may need to be iterative, as some derived variables may themselves be based on other derived variables. It is therefore important to ensure that variables are derived in the correct order. New units may be derived by aggregating or splitting data for collection units, or by various other estimation methods. Examples include deriving households where the collection units are persons, or enterprises where the collection units are legal units.

Meeting 3 April:
Action: to check with GSIM Revision group how they think about "statistical unit" vs. "unit". Also, "legal" or "collection" units?

GSIM Revision team agreed not to introduce the distinction in GSIM (can be considered to do at implementation level, maybe include some text in LIM document), see GSIM issue #93
