And so we come to the final batch of seats, covering Dublin City itself, with 527612 = 5.08 = 5 seats. The city north of the Liffey has 307495, which would work out for 3 seats; but it would leave the area south of the river with 220117, too big for two. So, to balance it out, one of the 'north' seats will have to include an element from the south.
57 - Dublin North West: 107820
Cabra-Finglas LEA (less the part of Phoenix Park ED): 55260
Ballymun LEA (minus Botanic B and C EDs): 52560
58 - Dublin North East: 105284
Beaumont-Donoghmede LEA: 73239
Beaumont D, E, F EDs: 7587
Raheny St Assam ED: 3501
Clontarf East EDs: 17521
Clontarf West A ED: 3436
59 - Dublin Central: 105399
This is the seat to cross the Liffey. It takes in Wood Quay and Royal Exchange, which seem like a natural addition to a 'Central' seat since they include some of the oldest parts of Dublin including the Castle and the two famous cathedrals.
Clontarf LEA (parts not in previous seat): 20313
Botanic B and C EDs: 5321
North Inner City LEA: 67309
Wood Quay EDs: 6151
Royal Exchange EDs: 6395
60 - Dublin South West: 105259
Crumlin-Kimmage LEA: 51894
Ballyfermot-Drimnagh LEA: 52896
Phoenix Park ED (the part in Cabra-Finglas LEA): 469
61 - Dublin South East: 103850
Pembroke-South Dock LEA (less Wood Quay EDs and Royal Exchange EDs): 56014
Rathgar-Rathmines LEA: 47836
And that's it. Phew. Comments of course welcome.
