In the United States it was anticipated that when retail sales became known that fact of itself would provide an unfailing in dex, sufficiently accurate for practical purposes. But such ex ceptions as the sales of food stores illustrate the inadequacy of this as a one item index. In urban districts, green vegetables, eggs, and butter and milk are among the items bought, while in rural districts these items are largely provided by the home. So in computing an index for the sale of a package cheese, food store sales would indicate too much for cities and not enough for towns and villages. Most other items have similar exceptions, so the careful marketing man compiles an index, and verifies estimates by all available data. (H. E. A.) MARKETING. Marketing is essentially the distribution of goods from the producer to the consumer. The central fact is the sale, but to secure sales the goods must be assembled from the places where they were produced, graded when qualities differ, sorted when there are different varieties, stored, moved to market and in many cases thence to the place of consumption. All of these processes constitute a part of the marketing operation.
