Under the Local Government Reform Act 2014, only Dublin, Cork and Galway retain separate city councils. Limerick and Waterford were merged into the corresponding county councils and all borough and town councils were abolished. Municipal districts were created from local electoral areas, with councillors being those elected to the county councils. In the case of Limerick and Waterford, these are called Metropolitan Districts, while in the case of Drogheda, Wexford, Sligo and Clonmel, these are called Borough Districts.
The first name listed is the commonest English name, and links to the relevant article. Alternative names are listed in parentheses. If the official name used in census reports is not the linked name, it is in italics. Only the name of the municipality is given, not that of any suburban areas (e.g. Tallaght is not named separately from Dublin).
The Local Government Act 2001 defines three types of municipal council, namely "City", "Borough", and "Town". The "Town council" label replaced the earlier "Urban district council" and "Town commissioners", but did not abolish the distinction in their respective powers. Values listed in this column `are as follows:
For the few ancient boroughs whose charters were not extinguished by the Municipal Corporations (Ireland) Act 1840 or promoted to the status later. Their powers are practically identical to those of the former urban districts, but the label "borough" is more prestigious. Abolished in 2014.
The Local Government Act, 1994 extended the boundaries of some towns for electoral purposes only. That is, people living outside the municipal area were entitled to vote for the town council even though their residence was outside its jurisdiction. In a few cases, the municipal boundary of the town was subsequently extended to remove this anomaly. The remaining cases are marked by an asterisk in this column. Where the municipal area changed between the 2006 census and the 2009 election, this is noted. (No municipal area changed between the 2009 election and the 2011 census.)
Called "Suburbs" for cities and "Environs" for boroughs and towns. Defined as "the continuation of a distinct population cluster outside its legally defined boundary in which no occupied dwelling is more than 200 metres distant from the nearest occupied dwelling. In applying the 200-metre criterion, industrial, commercial and recreational buildings and facilities are not regarded as breaking the continuity of a built-up area. New suburbs or environs are defined only where there are at least twenty occupied dwellings outside the legal boundary within the new limit."

For City, Borough, and former UD towns, there is an explicit summary row in Table 6 for the town.
For former commissioner towns, the area is that of one or more electoral divisions in a rural area of the relevant county. These divisions are noted.

Those towns which had their boundaries extended, for electoral purposes only, in 1994, represent an anomaly, as residents of the environs of a town may help elect the town council but do not fall within the functional area of the council. A number of these towns’ boundaries have been altered since 1994, however in the majority of cases the anomaly continues to exist. The correction of this anomaly would appear to be in order.Cite uses deprecated parameter |deadurl= (help)
