Which constituency do I live in?

The Senedd Elections are less than two weeks away, with voters preparing to chose who they want to represent their communities in Cardiff Bay.

For Senedd Elections, Wales is divided into 40 constituencies. Each constituency elects one Senedd Member to represent them.

The constituency boundaries are currently the same for UK Parliamentary elections.

The Caerphilly constituency, as well as the Islwyn constituency, both fall completely within Caerphilly County Borough.
The Merthyr Tydfil and Rhymney constituency covers the Upper Rhymney Valley area of Caerphilly County Borough, as well as the entirety of Merthyr Tydfil County Borough.

The constituencies are made up of the following council wards:
