A breakdown of cases of Covid-19 according to Dublin postal district shows that around one in six cases were recorded in just two postal areas.

The figures, released by the HSE under FOI, show that the postal code with the highest number of cases recorded at the end of May was Dublin 24 with 1,076.

It was followed by Dublin 15 with 873 cases.

Both are sprawling areas and heavily populated, with Dublin 24 centred on Tallaght and Dublin 15 including Blanchardstown, Castleknock, and surrounding areas.


The statistics are the most detailed glimpse at the geographical spread of the disease around the capital since the outbreak first began in the city in late February.

Some of the figures are influenced by the fact that certain areas of Dublin have more long-term residential care facilities than others.

The highest number of cases - 2,387 infections - was recorded under the heading "Co Dublin", which includes areas in both the north and south of the city.

In particular, it encompasses heavily populated areas in the south of the city like Blackrock and Dun Laoghaire, while in the north of the county it covers places like Balbriggan and Lucan.

Dublin 11 - an area centred on Finglas and its surrounds - had 777 cases.

Dublin 9 - which includes Drumcondra, Beaumont, and Santry and was thought to be the location for the first confirmed case in Ireland - had 622 cases.

Next on the list was Dublin 7 with 506 cases. That area of the city includes Cabra, Phibsboro, Stoneybatter, and other parts of the north city.

The next highest figure was in Dublin 6, where 505 cases had been recorded as of the end of last month. Dublin 6 is made up of areas like Ranelagh, Rathmines, and Rathgar. Its neighbouring district Dublin 8 had the exact same amount of cases at 505, according to the records.

Another 487 infections were recorded in Dublin 5, an area covering Artane and Raheny, while 403 cases were found in Dublin 12, made up of the areas of Crumlin, Drimnagh, Walkinstown and Bluebell.

Between three and four hundred cases were found in each of Dublin 18 (370), Dublin 16 (325), Dublin 3 (310), and Dublin 22 (304). Less than 300 cases were confirmed in Dublin 14 (276), Dublin 4 (271), Dublin 13 (270), Dublin 17 (249) and Dublin 20 (239).

Just 194 cases were found in Dublin 1, the heart of the north inner city, while 102 cases had been confirmed in Dublin 2, on the other side of the River Liffey.

Of the suburban postal codes, the small area of Dublin 10 - covering primarily Ballyfermot - had the lowest figure, at just 164 cases.

Not included in the figures were some 876 cases in Dublin where only an incomplete address was available or an address outside of Ireland was provided.

In providing the figures, the HSE also said that some patient addresses reflected the location of their residential care facility and not their previous permanent residence.

The data is accurate up to May 31, when 25,059 cases had been confirmed in Ireland, around 48pc of them in Dublin.

Since then, the total has risen by less than 200, with the number of cases being reported each day in June having fallen dramatically.
