摘要：Description and explanation of dynamic changes within the United States of America agriculture make the scheme of this article. The authors analyse the structure and the dynamics of changes in American agriculture over the last thirty years. During that period the number of farms was reduced by great rate but their individual size enlarged (the average largeness of nowadays farm is over 200 ha). Despite the improved economic and technological conditions, the income from agriculture makes smaller and smaller part of the farmers’ families earnings while the wages from other occupations out of farms are prevailing. The structure of consumption and the nourishment habits have also notably changed. The consumption of certain sorts of meat is going down, while that of vegetables, fruits, poultry and fish is increasing. Today only 2% of active population is occupied with agriculture and approximately one fifth of American population lives in rural areas.
