Description: This report discusses how drought is defined (e.g., why drought in one region of the country is different from drought in a different region), and why drought occurs in the United States. The report briefly describes periods of drought in the country's past that equaled or exceeded drought conditions experienced during the 20th century, including periods during earlier centuries where the American West was substantially drier, on average, than it is today.
