Production has shifted to larger farms in most agricultural commodity sectors over the last two decades. This consolidation has contributed to productivity growth in agriculture, leading to lower commodity and food prices and reducing total resource use in food and fiber production. As consolidation reduces the farm population, it also makes starting small and mid-sized farming operations more difficult. This is especially true for dairy farms, where a major transformation of the sector has reduced the number of dairy farms by nearly 60 percent over the past 20 years, even as total milk production increased by one-third. Recent results from the Census of Agriculture and the Agricultural Resource Management Survey (ARMS) detail how and why the structure of dairy production has changed.
The "midpoint" herd size is now at 900 cows.
