According to the 2012 Census of Agriculture, the number of farm operations in the United States has declined by more than 4.3 percent since 2007. This supports the common notion that US farms are consolidating and increasing in size. A key issue facing the professional farm management industry is how the changing structure of US agriculture might impact future demand for their services. This article uses farm-level data from Illinois and from various years of the US Census of Agriculture to look at this issue more closely, focusing on the services offered by farm management associations. Farm types or sizes which are more likely to be members of a management association are identified, and trends in the number of these farm operations are examined at regional and national scales. The data suggests that the number of farms across the US who are more likely to ,demand services from farm management associations is likely increasing, but these changes are highly regional in nature.
