Variable Groups

Variable Groups are used to group together closely related variables. Under the DDI each system of categories is defined as a separate variable, so for example a variable categorising ages into five year bands running up to '95 and over' is a separate variable from one giving ages to '100 and up'. However, we group these into a single Variable Group covering ages.

The following Variable Groups are currently defined:
