Net farm income is affected by changes in final demand, in marketing charges, and in production costs. BAE publishes data relating to each of these three sets of factors. This article attempts a new combination of these data for a recent year, with agriculture divided into nine major commodity groups. Although the tentative and preliminary nature of the data must be emphasized, information of this kind is needed for several purposes, including estimation of the effect of changes in specific marketing and production cost items upon net income from different commodities. The success of newer approaches to the study of relationships between agriculture and the general economy also depends upon the development of accurate and detailed information of this kind.
