Welsh election: Why did most people not vote?

Most people did not vote in this month's Senedd election.

A record 1.1 million (47%) of them did vote but Merthyr, Swansea East and Torfaen were the constituencies with the lowest turnouts - 34.8%, 35.4% and 37.3% respectively.

Is it down to lack of interest? Lack of knowledge? Too busy? Forgetfulness? Disillusionment?

BBC Wales' political correspondent James Williams went to speak to people living in those areas to find out.
