Blackshaw is a predominantly rural South Pennine Parish within the area of Calderdale Metropolitan Borough Council and is a part of the Calder Valley Parliamentary Constituency. The bulk of the Parish is part of the Calder Terrace moorland fringe and upland pasture framed by the moorland tops, Noah Dale, the wooded Colden and Jumble Hole Cloughs and crossed by the Pennine Way. The Parish stretches from the valley settlement of Charlestown on the busy A646 between Hebden Bridge and Todmorden to the high moorland plateau on the border with Lancashire at Hoof Stones Height (479 metres high). The upland settlement of Blackshaw Head sits on the ancient trans-Pennine “Long Causeway” 12 miles from Halifax and 7 miles from Burnley. The 2011 census estimated a population of 963 in the parish for mid 2010.
The area is served by two primary schools, Colden Junior and Infants and Hebden Royd, both of which are just outside the Parish Boundary.
The only shop in the parish is Great Rock Co-op, selling local farm foods on Saturdays from 10:00 am to 2:00 pm. “Mays” farm shop is close to the parish boundary at Colden, the closest Post Office is in Heptonstall.
