From the Washington Post, where there is an interactive map:
There were 2,621,514 goats in the United States as of 2012, the year of the most recent USDA Agricultural Census. If America's goats were their own state, its population would be larger than that of Wyoming, Vermont, D.C. and North Dakota -- combined.
You might say that goats are having a moment. NPR's new-ish blog on "stories of life in a changing world" is called "Goats and Soda," a nod to the animal's ubiquity in many parts of the developing world. Closer to home, goats are being used in urban areas to trim grass and control brush.
[There were 506 goats in Albany County, NY but none in the Bronx, alas.]
