Aggregation

From Open Risk Manual

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.[1]
