A Graphic Summary of American Agriculture Based Largely on the Census

Excerpts from the Report: This publication is a revision and enlargement of A Graphic Summary of American Agriculture contained in the 1915 Yearbook of the Department of Agriculture, which was also issued as Yearbook Separate 681, and of a second contribution having the same title in the 1921 Yearbook, which was also issued as Yearbook Separate 878. The first edition was based largely on the 1910 census of agriculture, the second on the 1920 census; this revision portrays similarly the returns from the 1925 census, supplemented by a number of maps based on the annual estimates of the United States Department of Agriculture. Extensive and significant shifts have occurred in the areas of crop and livestock production since the pre-war years, and even since the World War. Maps have, therefore, been included in this revision showing the increase and decrease in the principal crops and kinds of livestock between 1909 and 1924 (1910 and 1925 for livestock) and between 1919 and 1924 (1920 and 1925 for livestock), while several other maps show regional changes between 1924 (or 1925) and 1928 (or 1929). Still other maps show percentage changes since 1919 or 1920
