Aggregation

Definition

Aggregation, in Accounting context, is the addition of assets, liabilities, equity, income or expenses that have similar characteristics and are included in the same Classification.

In Input-Output Model context, aggregation denotes the combination of detailed subgroups (of e.g. products, regions or sectors) to form a larger group. For example, detailed I-O items are aggregated to I-O commodities, and detailed industries are aggregated to summary industries and sectors for publication.
