A new Constituency Commission report on election boundaries (for general and European elections) is likely to be published in the coming weeks after the final/definitive population statistics for Census 2011 were published today. This posts follows on the previous posts in this series which updates the analysis carried out previously for 154-Dail seat and 160-Dail seat scenarios to consider what options the Constituency Commission might face if they decide to opt for a 158-seat Dail Eireann.

A new Constituency Commission report on election boundaries (for general and European elections) is likely to be published in the coming weeks after the publication of final/definitive population statistics for Census 2011 by the Central Statistics Office today.
This post will consider what might happen our current constituency configurations if a 160 seat tally was agreed on for the next Dail and in light of the provisional Census 2011 population levels published by the CSO last year. While the Commission has a range of options to choose from between 153 and 160 in terms of seat numbers for the next Dail, the likelihood is they may opt for a seat tally towards the upper range of this as continued population growth may require seat tallies to be constantly changing if they opt for a seat tally at the lower end of this scale.
The key thing that the Commission will be watching for in this review are constituencies whose population per TD ratios fall outside the 5% variance limit – that is, whose population per TD ratios are either more than 5% above, or below, the state average for this (in the case of a 160-seat Dail, the state average would be 28,677 people per TD). In these cases, the Commission must consider whether they need to make changes to the boundaries/seat numbers for these constituencies. On past precedents, they may opt not to make changes if the level of variance is not much higher than this 5% limit (as happened in the case of Cavan Monaghan in both the 2004 and 2007 revisions) but they must make changes if the level of variance exceeds 7.89% – the maximum level of variance permitted by past commissions (Mayo East in the 1983 revisions).
So what might happen to our current constituencies in the light of the decision to reduce the number of Dail seats and the population changes outlined in the definitive 2011 Census population by area figures, if the Constituency Commission were to opt for a 160-seat Dail Eireann?
Adrian Kavanagh, March 29 2011
The definitive Census 2011 population figures have been published today. Election boundary changes (for general and European elections) will be made on the basis of these, but this time are taking place in the context of a decision by government to advise a reduction in Dail seat numbers by between 6 (160 seats) and 13 (153 seats). So what do these population figures mean in terms of which constituencies may, or may not, be likely to have their election boundaries changed following on the upcoming Consituency Commission report, especially given that this body effectively will have eight different options in terms of total Dail seat numbers to choose from? The following document, which outlines the degree to which each constituency’s population per TD ratio will vary (in percentage terms) from the state average for each of the different seat number options open to the Commission, should help in regard to this.
What is evident from this analysis is that the main driver of change in relation to the redrawing of Dail election boundaries this time will probably be more so the decision to reduce Dail seat numbers over and above those changes required by differential levels of population change within the state. Had the number of seats remained at 166, changes to constituency boundaries would have been absolutely necessary in just 12% of cases (where level of variance exceeds 7.89%) and would have been probable in a further 21% of cases (where level of variance exceeds 5% but not 7.89%). When you are faced with a 160-seat option (the largest option open to the Constituency Commission), changes to constituency boundaries would now be absolutely necessary in 23% of cases (where level of variance exceeds 7.89%) and would be probable in a further 26% of cases (where level of variance exceeds 5% but not 7.89%). The level of changes required further increases in line with decisions to reduce Dail seat number by even higher levels and for a 153-seat option (the smallest seat number option open to the Constituency Commission), changes to constituency boundaries would now be absolutely necessary in 49% of cases (where level of variance exceeds 7.89%) and would be probable in a further 23% of cases (where level of variance exceeds 5% but not 7.89%).
One interesting point to note is that if the population increase between the 2011 Census and the next census in 2016 proved to be exactly the same as that between 2006 and 2011 the population in the Republic of Ireland would then stand at 4,965,286. Given the requirement in the Constitution that there be one TD for every 30,000 people (a factor that limited the possible reduction in Dail seat for the 2011-12 Constituency Commission revision to a range between 6 and 13, as the smallest number of Dail seats you can have with a population of 4,588,292 is 153), the smallest number of Dail seats that the Commission would be able to choose in the next revision would be 166 based on aprojected 2016 population figure of 4,965,286, which of course is the current seat level in Dail Eireann.
It is also worth noting that based on the cubic root rule, the idea parliament size for a population of 4,588,292 would be…166 seats.
Given the impressively small level of variation between the provisional (based on enumerator returns) and definitive population figures for the constituencies, my earlier posts (which were based on the provisional figures) as to what might happen in relation to decisions to be taken by the Constituency Commission in relation to changes to Dail election boundaries still largely hold true. But I have updated these to take account of the newer, and definitive, Census 2011 population figures. A more detailed version of this post may be viewed at the Ireland After NAMA blog.

With a referendum pending on the abolition of the Seanad also, this might also persuade the Commission to not take a more radical approach in terms of reducing the number of seats in the Dail.
The key thing that the Commission will be watching for in this review are constituencies whose population per TD ratios fall outside the 5% variance limit – that is, whose population per TD ratios are either more than 5% above, or below, the state average for this (in the case of a 158-seat Dail, the state average would be 28,995 people per TD).

This post will consider what might happen our current constituency configurations if a 154 seat tally was agreed on for the next Dail and in light of the provisional Census 2011 population levels published by the CSO last year.

This scenario has been considered in the previous post, so this post will instead consider what might happen if the Commission were to opt for a number at the lower end of this scale, say 154 seats.
As noted earlier, the key thing that the Commission will be watching for in this review are constituencies whose population per TD ratios fall outside the 5% variance limit – that is, whose population per TD ratios are either more than 5% above, or below, the state average for this (in the case of a 154-seat Dail, the state average would be 29,749 people per TD).

Some months after the publication of provisional population by area figures by the Central Statistics Office for the 2011 Census, a new Constituency Commission was set in place to begin the process of redrawing European and general election constituency boundaries in light of the changes in population between 2006 and 2011 as revealed in these figures. The other main factor for the new commission to consider was the decision to reduce the number of TDs in the next Dail, in keeping with government reccomendations and the stipulations set out in the 2011 amendment to the Electoral Act. The process commenced much earlier for this Commission than for previous ones, in which the process has started after the publication of the final, or definitive, population by area census figures by the CSO. Following the ruling on the McGrath/Murphy high court case in 2007, the Commission must now commence the process of redrawing Dail and European election constituency boundaries after provisional census figures are published although they cannot publish the final report until after the final or definitive population by area census figures have been published. Given that there tends to be little difference between provisional and final census figures for large areas such as constituencies, very few final tweaks may be needed should a draft version of the final report be available ahead of the publication of the final census figures and the published report is likely to be available some weeks after these figures are released.
In total, 533 public submissions were made to the Constituency Commission between the receipt of the first submission on 22nd September 2011 and the closing date for submissions (10th January 2012). This compared highly favourably with the level of submissions for the two previous cases, with 335 submissions made in the case of the 2007 Constituency Commission and just 99 submissions made in the case of the 2004 Constituency Commission.
