Statistical concept
Definition
A process that transforms microdata into aggregate-level information by using an aggregation function such as count, sum average, standard deviation, etc.
Context
Aggregation denotes the compounding of primary data into an aggregate, usually for the purpose of expressing them in a summary form. For example, national income and price index numbers are aggregative, in contrast to the income of an individual or the price of a single commodity.

With standard hierarchical classifications, statistics for related categories can be grouped or collated (aggregated) to provide a broader picture, or categories can be split (disaggregated) when finer details are required and made possible by the codes given to primary observations (United Nations Glossary of Classification Terms, http://unstats.un.org/unsd/class/family/glossary_short.asp).

A special case of aggregation is the grossing up of samples.
