Stratford sub Castle boundaries - MSOA
The area within the black border shown on the image is designated 'Salisbury - Stratford' by Government Agencies when statistics are provided by MSOAs (Middle layer Super Output Areas) and most recently has been used when providing COVID case data.
Note that the designated area extends across to and beyond Devizes Road, northwards beyond Little Durnford, eastwards beyond the A345 Salisbury to Amesbury Road, and southwards beyond the Ring Road.
The area that residents might consider to be 'Stratford' would be too small to qualify as an MSOA as MSOA areas typically have a population of between 7,000 - 10,000.
