Again, no.
West Ham is in East London, but it’s not in the East End, as it’s East of the River Lea, and therefore traditionally part of Essex, before the administrative borders of London were expanded.
The East End is the area between the City of London and the River Lea.
Lots of people who live in West Ham (and other areas of East London and also Essex), would call themselves Eastenders though, as that’s where many of them have family origins.
All clear, isn’t it?
