You may have hoped that the national attention paid to organic farming, antibiotics, and other issues affecting the food you eat has resulted in a downturn in the number and size of factory farms over the years.

Unfortunately, you’d be mistaken. National advocacy group Food & Water Watch has been tracking the nation’s factory farms for years now, and the news isn’t good. The group recently released a report called Factory Farm Nation, which updated their interactive farm map, showing that the size, location, and number of animals on factory farms has risen significantly over the past 15 years–as has the amount of waste that those animals are producing.

Food & Water Watch Executive Director Wenonah Hauter points to deals like Hormel’s recent acquisition of Applegate Farms as evidence that the trend for consolidation, and the bigger farms that come alongside it, is not letting up.

“As factory farms grow in size and number, so too do the problems they create, such as increased water and air pollution; fewer markets for independent, pasture-based farmers; public health burdens like antibiotic-resistant bacteria; and large scale food safety risks for consumers,” she said in a statement.

The organization compared U.S. Department of Agriculture (USDA) census data from four years–1997, 2002, 2007, and 2012–to look at the macro trends affecting the national factory farm landscape. It found that the total number of livestock on the largest factory farms rose by 20 percent between 2002 and 2012, increasing the number of livestock units from 23.7 million to 28.5 million. The trend was similar for dairy, hog, broiler chicken, egg-laying hens, and cattle operations. Here are some other facts from the report:

The number of dairy cows doubled on farms in those 15 years, and the average size of dairy farms grew by half.
Hog farm size grew by nearly 70 percent, with a third more hogs on each farm.
The average size of U.S. broiler chicken operations rose by about 5 percent, but the number of chickens on those farms rose by about 80 percent, to more than 1 billion. The average size of egg operations rose by nearly 75 percent, with about a quarter more hens per farm.
Though the 2012 drought reduced total cattle heads, feedlots size increased by 13.7 percent between 2007 and 2012.

Food & Water Watch’s definition of “factory farm” included operations that had at least 500 beef cattle heads, 500 cows, 1,000 hogs, 100,000 egg laying chickens, or 500,000 broiler chickens sold annually.

Whether you parse the information on the site by state or type of cattle, or get an overview of the country, the up-and-to-the-right trend is almost unvarying.
