In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Arden like this:
ARDEN-WITH-ARDENSIDE, a township in Hawnby parish, N. R. Yorkshire; 7½ miles NW of Helmsley. Acres, 4,513. Pop., 129. Houses, 25. The surface is chiefly part of Humbleton moor. A Benedictine nunnery was founded here in 1150; but has disappeared.
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 Arden has changed, please see our redistricted information for the modern district of Ryedale. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Arden and units named after it.
