Variable Group : Age

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.

Text:
Many different categorisations of age have been used in statistical reporting over the years. Five-year ('quninquennial') bands appear in many categorisations, but they still differ in the threshold used for the catch-all top band: some reports lump together everyone over 65 while many 19th century censuses distinguished between those aged 95-99 and those over 100.
