In 1887, John Bartholomew's Gazetteer of the British Isles described Garstang like this:
Garstang, market town, par., and township (ry. sta. Garstang and Catterall), N. Lancashire, on river Wyre, 10½ miles S. of Lancaster -- par., 29,422 ac. and 4439 foreshore, pop. 6645; township, 503 ac., pop. 783; town, pop. 2769; P.O., T.O., 2 Banks. Market-day, Thursday. The neighbourhood contains several very large cotton factories.
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 Garstang has changed, please see our redistricted information for the modern district of Wyre. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Garstang and units named after it.
