A hundred is an administrative division that is geographically part of a larger region. It was formerly used in England, Wales, some parts of the United States, Denmark, Sweden, Finland, Norway, and in Cumberland County in the British Colony of New South Wales. It is still used in other places, including in Australia (in South Australia and the Northern Territory).
Other terms for the hundred in English and other languages include wapentake, herred (Danish and Bokmål Norwegian), herad (Nynorsk Norwegian), härad or hundare (Swedish), Harde (German), hiird (North Frisian), kihlakunta (Finnish), and cantref (Welsh).
In Ireland, a similar subdivision of counties is referred to as a barony, and a hundred is a subdivision of a particularly large townland (most townlands are not divided into hundreds).
