Farm Size, Farm Structure, Energy and Climate: An Alternate Ecological Analysis of United States Agriculture.

The Census of Agriculture is an important source of data for persons interested in studying the structure of agriculture. The census has been used to study agriculture and quality of life in Kansas recently and aggregated state level data was used to describe the relationship between farm size, agriculture and energy consumption. As sociological interest in agriculture, grows, it is likely that the Census of Agriculture will become the source of many more studies. Unfortunately, the units of analysis reported in the Census of Agriculture like-aggregate national, state and county statistics-create problems for those who use them for sociological purposes. This short article will illustrate some of the problems inherent in the use of census materials by reexamining some of the data used on recent papers on energy and agriculture. A serious difficulty posed by the use of census material for sociological research stems from the fact that census data are aggregated on the bases of political units like states and counties.
