Why Small Dairies Vanish, or Turn Organic

From Modern Farmer, talking about a USDA survey of dairy farms:

The data will also be used to study the economy of scale in the dairy industry. Kings says that based on data from the 2010 ARMS, dairies with less than 50 cows had production costs twice that of dairies with 1,000 cows or more. “This cost-size relationship means that large dairies account for an increasing share of milk production and small dairies are going out of business, often as small producers reach retirement,” she says.
