As an exercise in measuring OSM’s coverage I have crunched the numbers in GregRS’s CSV output to calculate the number of OSM candidates in each district as a proportion of the number of FHRS entries that the program reports. The figures are a bit arbitrary and values over 100% are not necessarily wrong. The tool doesn’t cover Northern Ireland.
The list is: 1 Tendring 135.07% 2 Gravesham 117.93% 3 Isles of Scilly 117.81% 4 Rushcliffe 117.58% 5 Blackpool 108.66% 6 East Northamptonshire 108.17% 7 Wellingborough 107.94% 8 Guildford 107.82% 9 Erewash 106.40% 10 Broxtowe 106.14% 11 Argyll and Bute 105.49% 12 Islington 104.16% 13 Gedling 98.48% 14 South Cambridgeshire 97.83% 15 Edinburgh 97.60% 16 Nottingham 97.45% 17 Derbyshire Dales 97.07% 18 Cambridge 96.83% 19 Allerdale 94.78% 20 Wychavon 94.78% 21 West Devon 94.47% 22 Bath and North East Somerset 93.83% 23 Oxford 93.09% 24 Aberdeenshire 92.90% 25 Ryedale 90.70% 26 Mid Devon 89.31% 27 Central Bedfordshire 88.97% 28 Westminster 87.99% 29 South Norfolk 87.13% 30 South Lakeland 86.94% 31 Amber Valley 86.34% 32 Birmingham 85.27% 33 Poole 84.66% 34 Melton 83.60% 35 Lancaster 82.43% 36 Southampton 82.31% 37 South Ribble 81.76% 38 Basingstoke and Deane 81.49% 39 Sevenoaks 81.44% 40 Staffordshire Moorlands 81.22% 41 Camden 81.09% 42 South Hams 80.09% 43 Copeland 79.87% 44 Carlisle 79.84% 45 Gateshead 79.72% 46 Hart 79.69% 47 New Forest 79.65% 48 Winchester 79.49% 49 High Peak 79.23% 50 Eden 78.69% 51 South Tyneside 78.59% 52 Rutland 78.34% 53 Perth and Kinross 77.14% 54 Derby 77.05% 55 East Cambridgeshire 76.82% 56 Shetland Islands 76.34% 57 Breckland 76.18% 58 North East Derbyshire 76.15% 59 Bristol 75.91% 60 Huntingdonshire 75.45% 61 Rother 75.34% 62 Sir Ynys Mon -
