A general trend in the last century has been for greater consolidation among Grain Merchants and Oilseed Millers and Processors. The U.S. Census Bureau tracks the number of firms and/or establishments and value of sales (market size) by industry sector every 5 years as a part of the Economic Census. In addition to the number of firms and sales, the Census Bureau publishes concentration ratios for each sector.
