The following information is applicable to data set specifications only.
Statistical units are the basic counting unit for a collection, meaning that a record is created within the collection for each new occurrence of the statistical unit.
Statistical units should reflect the actual underlying methodology of the collection (i.e. a record is created within a data collection for each new occurrence of the statistical unit).
The field should be used to clearly identify the statistical unit of the data set specification. Where the statistical unit is defined as a metadata item elsewhere in METeOR (e.g. Object class, Glossary item) it should be linked using hypertext.
