Excerpt from Population and Land in World Agriculture: Recent Trends and Relationships In the fourth and final part, a general theory of the growth of the agricultural labor force is presented. Three hypotheses to explain the growth of the agricultural population are developed on the basis of the material presented in the earlier sections and other evidence, and then tested by means of regression analysis. A substantive discussion of the regres sion results leads us to a generally satisfactory explanation of the growth of the agricultural labor force.
