In which dairy region is milk production most concentrated in the U.S.?

The region in which milk production is most concentrated in the U.S. is Wisconsin. This state has a long-standing history as a leading dairy producer, known for its large number of dairy farms and strong emphasis on cheese production. Wisconsin's favorable climate, rich soil, and a robust agricultural infrastructure support extensive dairy farming. Over the years, it has developed a reputation for high-quality milk and dairy products, making it a significant contributor to the nation's overall milk output.

While California is also a major dairy state and has the highest overall milk production volume, it is often characterized by larger dairy operations and less concentration in terms of the number of farms compared to Wisconsin. Florida and New York, while they do have dairy production, do not match Wisconsin's level of concentration and historical significance in the dairy industry.
