Aggregate income[1][2][3] is the total of all incomes in an economy without adjustments for inflation, taxation, or types of double counting.[4] Aggregate income is a form of GDP that is equal to Consumption expenditure plus net profits. 'Aggregate income' in economics is a broad conceptual term. It may express the proceeds from total output in the economy for producers of that output. There are a number of ways to measure aggregate income,[5][6] but GDP is one of the best known and most widely used.
