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 Moor House has changed, please see our redistricted information for the modern district of Durham. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Moor House and units named after it.
