Consumption is the value of goods and services bought by people. Individual buying acts are aggregated over time and space. First, consumption may be divided according to the durability of the purchased objects. In this vein, a broad classification separates durable goods (as cars and television sets) from non-durable goods (as food) and from services (as restaurant expenditure). These three categories often show different paths of growth.
