What is 'Aggregate Demand' Aggregate demand is an economic measurement of the sum of all final goods and services produced in an economy, expressed as the total amount of money exchanged for those goods and services. Since aggregate demand is measured through market values, it only represents total output at a given price level, and does not necessarily represent quality or standard of living.
The aggregate demand curve can be thought of just like a demand curve for a firm. When the price level is high, aggregate demand is low; when the price level is low, aggregate demand is high. The aggregate demand curve lies in a plane consisting of the price level and income or output. It shows a downward slope with price level on the vertical axis and income or output on the horizontal axis. As such, the aggregate demand curve outlines the relationship between income or output and the price level.
