Estimated total U.S. sales of fluid milk products
are based on the Federal milk order in-area sales described above and sales of Class I products in California. These two data series together account for about 93 percent of total fluid milk sales in the United States. An estimate of total U.S. fluid milk sales is derived by interpolating the remaining 7 percent of sales from the Federal milk order and California data. Sales of individual fluid milk products are shown. Beginning in 2003, sales of flavored whole and fat-reduced milk products are reported as complete data for 2002 are now reported by California. Previously, sales of flavored products were included either in whole milk or the respective fat-reduced milk product. The California data are collected and published by the Dairy Marketing Branch of the California Department of Food and Agriculture; see http://www.cdfa.ca.gov/dairy

The estimated total U.S. sales data series includes monthly sales volumes and percent changes from the same month in the previous year.
