D1 lies entirely within the Dublin Central constituency of the Irish parliament, the Dáil. The Dublin Central constituency is one of the most densely populated and socially and ethnically diverse places in Ireland.[1] The postcode consists of most of the northern city centre,[citation needed] affluent white collar areas around and including Mayor Square,[citation needed] and traditional working class areas such as Sheriff Street.[2] In 2019, the Irish Independent reported that Dublin City Council embarked on a plan to improve lighting and surfacing in the area's laneways[3] while Ireland's National Tourism Development Authority has said the regeneration of a historic part of Dublin 1 tied to the Easter Rising is "long overdue".[4] The American Institute of Architects has been hired by a local business group to help regenerate the area, which they say faces "civic schizophrenia" and "a split personality".[5]
Colloquially, Dubliners simply refer to the area as "Dublin 1". The postal district forms the first part of numerous seven digit Eircodes that are unique to every single address in the area. For addressing purposes, it appears in both its original form as Dublin 1 and as the first part of a seven digit postal code as D01 a line below.[21] For example:
Dublin City Gallery The Hugh Lane
Charlemont House
Parnell Square North
Dublin 1
