The rise in plant-based sales from an average of 0.028 gallon per household per week in 2013 to 0.038 gallon per household per week in 2017 only represents about one-fifth of the size of the reduction in purchases of dairy milk. For comparison, Americans were purchasing 0.409 gallons of milk per household per week in 2013 and 0.359 by 2017.
Particularly in the last few decades, the dairy industry has watched fluid milk sales slide, though at the same time, cheese, butter, and yogurt have achieved remarkable sales gains. Clearly, dairy remains an important part of the diet, and for the most part, that extends to fluid milk. In every year of the ERS research, over 91% of households bought cow’s milk at some point. Even among people who bought plant-based products, more than 90% also bought cow’s milk.
Some of the factors the researchers believe are contributing more heavily to reduced fluid milk consumption include demographic changes that have resulted in a smaller share of young people in the U.S. and continued generational differences in demand for milk. There are also more options in the beverage case now, such as bottled water and soft drinks, and more meals eaten away from home, where milk is less frequently chosen.
