Water Use in the United States
Changes in Water-Use Categories
Water-use terminology has changed in the series of USGS water-use Circulars prepared at 5-year intervals. The category changes over time are illustrated here. In some changes categories were re-named but retained essentially the same definition, while other changes split existing categories or shifted components of one category to another. See the linked definitions of the categories for other details.
*Rural estimates for 1950 and 1955 were allocated to Rural Domestic and Livestock in later reports.
