The Aberafan & Maesteg Parliamentary Constituency covers the following electoral wards:

• Aberavon

At a Parliamentary level, the former boundaries remain in place until the next General Election, and the constituency is therefore covered by 3 Labour MPs – Stephen Kinnock MP (Aberavon), Chris Elmore MP (Llynfi Valley) and Christina Rees MP (Cimla & Pelenna).  Jamie Wallis is also the Conservative MP for Bridgend.

At Senedd level, the previous boundaries remain and the footprint is currently covered by David Rees MS (Aberavon), Huw Irranca-Davies MS (Ogmore), Jeremy Miles MS (Neath) and Sarah Murphy MS (Bridgend).

At a County Borough level, the Caerau; Cornelly; Llangynwyd; Maesteg East and West; and Pyle, Kenfig Hill & Cefn Cribwr wards are in the Bridgend County Borough Council area.  All other wards listed above fall under the Neath Port Talbot County Borough Council area.

The area is rich in tradition and is a home to Aberavon beach, Margam Country Park, and the TATA Steel Works.
