Why do some people say Romford is in Essex when they know it's not?

Some people refer to Romford as being in Essex due to its historical and administrative ties to the county. Although Romford is part of the London Borough of Havering and is technically within Greater London, its proximity to Essex and its roots in the county often lead to confusion. Additionally, the area's postal address, which includes Essex, reinforces this perception. This mix of local identity and historical context contributes to the ongoing debate about Romford's geographical affiliation.
