In 1887, John Bartholomew's Gazetteer of the British Isles described Ochil like this:
Ochil Hills, hill-range, chiefly in SW. Perthshire, but also within or bordering on Clackmannan, Kinross, and Fife; extends 25 miles NE. and SW. from near Perth, on the Tay, to near Bridge of Allan, in Stirlingshire; has an average breadth of 12 miles, and attains in Ben Cleuch an alt. of 23G3 ft.; the summits are mostly rounded and verdant, and there are many beautiful glens and valleys.
A Vision of Britain through Time includes a large library of local statistics for administrative units. For the best overall sense of how the area containing Ochil has changed, please see our redistricted information for the modern district of Perth and Kinross. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Ochil and units named after it.
