It is one of the most consistently safe seats for Labour; since the end of the Second World War, the Labour candidate has always won Aberavon with a majority at least 33%, and with the exception of 2015, the Labour candidate has also always won an overall majority of the vote in the seat. In 2015, Kinnock only won 48.9% of the vote in Aberavon, against a surge in the vote for the UKIP candidate; however, in 2017, Kinnock's vote share rose by 19.2 percentage points, the biggest increase in the Labour vote in the seat's history, and his majority increased to 50.4%, the highest for an Aberavon MP since 2001. The 2017 result also made Aberavon the safest Labour seat in Wales, however the seat saw a significant swing against Labour in 2019.

Commenting on the 1983 boundary changes to the constituency when moving the 2000 Loyal Address of the Blair Government in Parliament, the seat's then-MP Sir John Morris, who would retire at the next general election, said:
"It is a happy tradition on this occasion to refer to one's constituency and to the people who sent one here....Whatever may occur in future, I would deplore the loss of the Member-constituency link. When, after 23 years, I lost part of my constituency, I missed the friendship of two generations. My constituents and I had grown up and grown older together."
