Perth and Kinross (Scots: Pairth an Kinross, Scottish Gaelic: Peairt agus Ceann Rois) is one of the 32 council areas of Scotland and a Lieutenancy Area. It borders onto the Aberdeenshire, Angus, Argyll and Bute, Clackmannanshire, Dundee, Fife, Highland and the Stirling council areas. Perth is the administrative centre. It corresponds broadly, but not exactly, with the former counties of Perthshire and Kinross-shire.
Perthshire and Kinross-shire had a joint county council from 1929 until 1975. The area was created a single district in 1975, in the Tayside region, under the Local Government (Scotland) Act 1973, and then reconstituted as a unitary authority (with a minor boundary adjustment) in 1996, by the Local Government etc. (Scotland) Act 1994.From Wikipedia - click for full entry
