Centre points of the United Kingdom

There has long been debate over the exact location of the geographical centre of the United Kingdom, and its constituent countries, due to the complexity and method of the calculation, such as whether to include offshore islands, and the fact that erosion will cause the position to change over time.

[2] However, in 2002 the Ordnance Survey conducted studies that pinpointed the respective centres more precisely, and it is their results that are quoted below.

[3] The centroid is a mathematically derived point that is in every sense the centre of a two dimensional area like a piece of land.

If a line crosses an inlet of the sea then it can be considered as a stick of uniform weight with a material of negligible weight crossing the water, the line would then balance precisely at the centroid point if suspended.Put simply, the centroid is the point at which a cardboard cut-out of the area could be perfectly balanced on the tip of a pencil.

[4] Islands are assumed fixed to the mainland in their precise position by invisible rigid weightless wires.
