The Measurement of Average Farm Size

Abstract

Comparisons are regularly drawn between the average sizes of farms in particular countries or regions and in different farm‐type categories. Indeed average farm size is often considered to explain (or create expectations of) changes or differences in technical or economic efficiency through time or between countries. There are, however, a number of issues involved in specifying what is meant by a farm and in choosing a suitable measure of farm size. These are examined prior to a discussion of various measures of average size, one of which (the mid‐aggregate point) is described in some detail. The measures are illustrated with reference to agricultural holdings in England and in the Member States of the European Union.
