Portland in context
Distances are straight-line from the settlement's recorded coordinates. The 10 km figure sums the recorded places within that radius, so it describes how built-up the surroundings are rather than people per square kilometre.
The centre of Portland sits in postcode district DT5.
Council tax
The area Band D council tax for Dorset, the billing authority covering Portland, is £2,765 for 2026–27.
From MHCLG's council tax statistics (Table 9): the area average including police, fire and parish precepts, so it is the council's figure rather than the town's, and your own band depends on your property's 1991 valuation.
