Northern Ireland Local Elections: Maps

His name is Henry Reilly.
Didn't know his base was that concentrated, but am not surprised in the slightest. This is Ireland after all.

He is UKIP in Northern Ireland. Their vote everywhere else was derisory.

Why is the SDLP so strong around Derry?

A mixture of tradition (John Hume) and of actually being well-organised there.

You can see similar phenomena on a smaller scale in south Down (both in Downpatrick and the Warrenpoint/Rostrevor area) and in south Belfast (although there it owes a lot to demographic change).

IIRC, the wards in NI are 5 to 7 seats mostly, are they not?

Strictly speaking, wards in Northern Ireland are single seats. They're then combined to form District Electoral Areas with between 5 and 7 seats, which are what is used for elections.
