Farm Milk Components and Their Use Among Dairy Products Have Shifted Over Time

In 2000, U.S. farm milk contained 3.68 percent milk fat and 8.72 percent skim solids on average. By 2020, the milk-fat percentage had grown to 3.95 percent, and the skim-solids percentage had increased to 8.94 percent. For skim solids, content increased gradually from 2000 to 2020, while milk-fat content began rising in 2011, after remaining relatively steady from 2000 to 2010.
