Aggregate data
From Wikipedia, the free encyclopedia
In statistics, aggregate data describes data combined from several measurements. When you aggregate data, you replace groups of observations with summary statistics based on those observations.[1]
In economics, aggregate data or data aggregates describes high-level data that is composed from a multitude or combination of other more individual data.
- in macroeconomics data such as the overall price level or overall inflation rate
- in microeconomics data of an entire sector of an economy composed of many firms, or of all households in a city or region.
