The current Ballymun district is not substantially in the townland historically called "Ballymun" — instead, it occupies several nearby townlands, the most significant of which is Stormanstown. Due to what were seen to be undesirable associations, some say that the area has shrunk since the completion of the tower blocks. For instance, in the early days of Dublin City University (DCU), then called "NIHE, Dublin", this institution was sometimes referred to as being in Ballymun (part of the "Ballymun Project"), or sometimes in Whitehall, while today it is referred to and has a postal address in Glasnevin, even though it has not changed location. Indeed, much of the present day central Ballymun lies on lands once in the northern reaches of the "Albert Agricultural College" estate, the forerunner of the present-day DCU. Streets have also been renamed — for example, Ballymun Avenue (which was previously Collins Avenue Extension) was renamed Glasnevin Avenue after a local plebiscite in the 1970s.
