Introduction This question is very relevant to a property discussion forum such as this as people avail of accommodation and this drives demand which affects supply and cost. The demand can be direct – people buy their accommodation – or indirect – people seek to rent accommodation which others must acquire and make available for rent.
It also has potential wider social, cultural, economic and political relevance that I will cover briefly later.
So understanding demand is key to understanding trends in residential property prices and likely future trends.
Supply is easily ascertained through information on planning and building. Also, planning and building occur so slowly that the trends can be accurately determined for up to five years into the future. It is very unlikely that any residential property that will be available sometime in the next five years is not now at some discernible state in the planning or building pipeline.
I have long been disillusioned and dissatisfied with the official population statistics produced by the CSO. Their publically available information contains many internal inconsistencies – numbers stated in one area not agreeing with those elsewhere. However, my problems with the information are greater because I feel the CSO is undercounting the population size. I simply doubt their quality and accuracy of their data
From direct project experience, I know that the public service makes almost no use of CSO population data in planning and making decisions on policies. This is not because the departments feel the information is not accurate. Rather, it is because departments do not proactively plan. They react. The Department of Education does not seek to analyse the demand for education facilities – first, second and third level – in given locations and numbers of places in these facilities based on population. They just react after the fact to changes in demand.
The Department of the Environment does no plan for housing or infrastructure based on likely population changes. Again, they just react after the event at some considerable lag.
The Department of the Transport does not plan for roads or other transport infrastructure based on likely population changes and movement models. As with others, they just react after the event.
The information contained in this analysis comes for the limited publically available sources: Revenue Commissioners, Department of Social Protection, Department of Education, Central Statistics Office, Department of the Environment. It attempts to check data consistency across these channels. A more thorough analysis would require engagement with these organisations to attempt to resolve the data issues.
This is not an academic study. I do not have the time to apply such rigour to any analysis. There are plenty of state-funded institutions such as the ESRI and the CSO that could devote their large taxpayer-funded resources to such a study.
As usual, this is too long because I have shown my calculations and source material so others can review and question it, if they see fit. There are, unfortunately, not too many pictures to make it easier to read and understand.
There are all the usual issues of inconsistent start and end dates of data series that need to be addressed to create a coherent view.
Some Issues With CSO Population Data There are real issues with the CSO’s population data.
The CSO publish population estimates. Some of the relevant data series are:
• PEA01: Population Estimates (Persons in April) by Age Group, Sex and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0)
• PEA11: Population estimates from 1926 by Single Year of Age, Sex and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0)
They each give the estimate of the population in 2016 as 4,673,700.
The preliminary 2016 census of population from series such as:
• EP001: Population and Actual and Percentage Change 2011 to 2016 by Sex, Province County or City, CensusYear and Statistic (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0)
give the population as 4,757,976. That is a difference of 84,276.
Some differences will be accounted for because the two sets of data are not date-aligned. The census counts population in April. The estimates may be at the end of the year, though this is not stated.
The CSO calculate estimates by adding births, subtracting deaths, adding migration and subtracting emigration.
So, the 2011 census provides a baseline.
Code:
2012 estimate = 2011 population + births in 2011 – deaths in 2011 + immigration in 2011 - emigration in 2011
2013 estimate = 2012 population estimate + births in 2012 – deaths in 2012 + immigration in 2012 - emigration in 2012
…
2016 estimate = 2015 population estimate + births in 2015 – deaths in 2015 + immigration in 2015 - emigration in 2015
The numbers of births and deaths in a year are accurate. Any errors will be very small. There are very few unregistered births and deaths in Ireland.
Using this approach, the CSO underestimated their count of the population by 84,276. This error is therefore due to an error in calculation of immigration or emigration or both. The difference is left unfixed and unexplained, so far.
CSO Immigration and Emigration Numbers The CSO maintain a number of data series on immigration and emigration, such as:
• PEA17: Estimated Immigration (Persons in April) by Sex, Nationality and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0)
• PEA16: Estimated Emigration (Persons in April) by Sex, Nationality and Year (
http://www.cso.ie/px/pxeirestat/statire ... =0&PXSId=0)
The information in these is collected by surveys rather than the big count associated with the census.
If you consolidate these two, you get the following net view for the years 2006-2016:

In summary the totals for the years 2006-2016 are:
Code:
Emigration 768,100
Immigration 859,300
Net 91,200
The net figure for immigration over the years 2006-2016 seems far too low.
Now, when you look at the data series PEA21 which contains the CSO’s estimate of population based nationality: Irish, UK, EU and Other - PEA21 Estimated Population by Sex, Nationality and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0), you get:

Increase 277,400 1,200 94,000 68,100 440,700
The UK net increase number of 1,200 over this interval seem very low.
Note that this series still contains the inaccurate 2016 population number of 4,673,700.
When you summarise and consolidate PEA16 (emigration), PEA17 (immigration) and PEA21 (population) you get:

Then when you add details on births and deaths from VSQ01: Births and Deaths Registered by Sex, Quarter and Statistic (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0) you get:

2016 4,673,700 3,300 34,617
Total 440,700 91,200 457,186
An apparent net population increase of 440,700 but an increase of 548,386 based on adding the net immigration and net births over deaths numbers. Note that I interpolated the numbers of births and deaths for the two quarters 2016Q3 and 2016Q4 because they are not available in the VSQ01 series
The net difference between these two numbers is 107,686 which is greater than the difference between the 2016 population estimate and 2016 census number of 84,276.
So there are multiple inconsistencies across CSO demographic data: census, immigration and emigration, births and deaths.
This evinces poor data governance by and a lack of attention to data quality and an absence of master data management in the CSO. There does not appear to be any consistency or internal cross-checking, let alone cross-checking with external data sources.
It gives the appearance of multiple disconnected business units each focused on particular data sets not consulting one another and with no one taking overall responsibility or ownership.
Notes On Demographics These are some background notes on demographics that might be useful.
In a closed population, that is, one where there is no immigration and emigration, the number of people at age N in year Y will be less than or equal to the number at age N-1 in year Y-1. The difference will be due solely to deaths. The exception is those aged 0 in year Y which represents births during that year. Put simply, people are only born at age 0 and the number in subsequent years at ages 1 onwards never increases. It always drops for a closed population.
So for a real population, where the number of people at age N in year Y is not less than or equal to the number at age N-1 in year Y-1 that would be expected because of deaths, some external change (net migration) has occurred.

Irish mortality information is available in the Irish Life Tables Number 16 2010-2012
http://www.cso.ie/en/releasesandpublica ... 2010-2012/ The CSO has (erroneous) population estimates in the series PEA11: Population estimates from 1926 by Single Year of Age, Sex and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0).

This is just as example as we know that these CSO population estimates are wrong. The individual year-on-year error is around 17,000 (or possibly much higher).
For example, there were 35,692 males aged 1 in 2015. In 2016 the number of males aged 2 was 36,004. We would have expected 12 deaths in this age group. So, without any migration, the number of males in 2016 aged 2 should have been 35,680. But it was greater than this by 312. This indicates an external increase of around 324.
The Non-Death Difference column in the table above is the difference between the expected number at age N+1 in 2015 based on those at age N in 2015 and the expected deaths.
Any number that is significantly different from zero indicates net immigration or net immigration. It is not possible to determine the individual immigration and immigration of the net difference.
The ages where there in net emigration are 18-22. These may be Irish people going abroad the study or older children of Irish residents returning to their parents’ home country for activities such as study. This is not a property-buying cohort. It is only a small property-demanding cohort since many of them will be living with their parents. Their leaving will not free-up much property.
The components of change in Irish population are:

These are:
A – Births
B – Deaths
C – Immigration from Northern Ireland
D – Emigration to Northern Ireland, either native Irish, previous Northern Irish immigrants or other immigrants
E – Immigration from Great Britain
F – Emigration to Great Britain, either native Irish, previous British immigrants or other immigrants
G – Immigration from the EU
H – Emigration to the EU, either native Irish, previous EU immigrants or other immigrants
I – Immigration from the Rest of the World
J – Emigration to the Rest of the World, either native Irish, previous Rest of the World immigrants or other immigrants
The key to correct population information is knowing these components. Clearly the knowledge that exists about this is doubtful.
Migration Numbers and Numbers of PPSNs Issued The very large discrepancy between the immigration numbers and the number of PPSNs issued indicate a one or more of a number of problems:
• Undercounted immigration/undercounted population
• Errors by the Department of Social Protection
• PPSN abuse such as the EU Treaty Rights abuse that recently reported – see
http://www.independent.ie/business/brex ... 76592.html • Large volumes of short-term and repeated immigration with no PPSN reuse
In the time series PEA21: Estimated Population by Sex, Nationality and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0) which still has the inaccurate 2016 population number of 4,673,700, they estimate that 593,900 are migrants living in Ireland.
Of the extra 84,276 between the 2016 population estimate and actual, almost all will have been migrants. There are very few unrecorded births and deaths. So that is an estimate of 678,176 migrants living in Ireland. That is 14% of the population, according to the CSO.
Migration estimates are contained in PEA03 Estimated Migration by Age Group, Sex, Inward or Outward Flow and Year(
http://www.welfare.ie/en/Pages/Personal ... ssued.aspx). From 2001 to 2016, the CSO estimate that immigration in this interval was 1,188,000. Emigration is estimated as 905,400 giving net migration of 282,100.
This shows the CSO’s estimate of the proportion of immigrants in various age groups:

Not unsurprisingly, most (counted) immigrants are aged 15 – 44.
If you look at the series FNA02: Employment Activity of Foreign Nationals by Broad Nationality Group, Year of Entry and Year (
http://www.cso.ie/px/pxeirestat/statire ... =0&PXSId=0) which contains details on the PPS numbers issued from 2002 to 2014, the numbers are:
Code:
2002 79,859
2003 72,312
2004 116,207
2005 169,886
2006 202,395
2007 187,761
2008 127,048
2009 62,984
2010 59,310
2011 58,258
2012 64,193
2013 75,812
2014 85,724
Total 1,361,749
So, according to the CSO, immigration from 2001 to 2016 of 1,188,000 but 1,361,749 PPSNs issued in the shorter interval of 2002 to 2014.
Now, there is abuse of PPSNs with one person have more than one PPSN and there are people with PPSNs who are welfare tourists. But you need a PPSN to get pretty much any service:
• Any Social Welfare services
• Any Revenue Schemes including Taxation
• Pupil ID
• HSE services including Medical Card and Drug Payment Schemes
• Child Immunisation
• Housing Grants
• Driver Licenses
So, there are substantial incentives to get a PPSN.
Also, unless you are operating entirely in the black economy you or your employer will look for a valid PPSN.
The Department of Social Protection (DSP) also publish PPSN statistics, less than helpfully in PDF files, one for each year at
http://www.welfare.ie/en/Pages/Personal ... ssued.aspxWhen you consolidate the DSP PPSN details with the CSO PPSN and migration data you get:

Total 3,254,755 1,296,712 1,958,043 310,089 905,400
So:
• DSP issued 1,958,043 foreign PPSNs from 2001 to Sept 2016.
• CSO estimate immigration (gross and not net) of 905,400 in the same interval
• Even in the interval 2002 to 2014 for which the CSP published foreign PPSN details, there is a difference of 310,089 between the CSO and DSP numbers
That means that the Department of Social Protection issued more than twice the number of PPSNs to non-nationals than the CSO estimate immigrated into Ireland.
It points to possibly much larger numbers of non-national migrants than officially stated in the interval 2001 to 2016.
This is a further view of consolidated information for the years 2006-2016 which matches the interval for the demographic data in the previous section:

Total 2,134,542 883,338 1,251,204 768,100 644,300 774,484
There were 883,338 PPSNs issued to Irish people and 774,484 births. All new births are assigned PPSNs. The difference can easily be accounted for by factors such as older Irish people, who would not have PPSNs, immigrating,
The CSO estimate non-Irish immigration of 644,300 in this interval. The Department of Social Protection issued 1,251,204 PPSNs to non-Irish people in the same interval. That is a very substantial and unexplained difference of 606,904. This difference is just too large to be left unexplained and unquestioned.
EU nationals living in Ireland with children living elsewhere in the EU are entitled to Children’s Allowance. But, as far as I believe, these children do not get assigned a PPSN. Maybe someone who knows more can provide more information on this. The number of such children being paid Children’s Allowance is low and much lower than 606,904.
That is a potentially a lot of extra people looking for accommodation, rental or otherwise, driving demand and cost.
It is also a lot of inconsistency and lack of certainty.
Widening The Data Net The data net can be widened to attempt to answer the question and to cross-check the reliability of the CSO’s population data.
Population-related information can be obtained from other sources such as the Revenue Commissioners – details on the numbers of income tax payers – and the Department of Education from which details on number of students in education are available.
This shows the population estimates from the CSO series PEA11: Population estimates from 1926 by Single Year of Age, Sex and Year (
http://www.cso.ie/px/pxeirestat/Statire ... Language=0). I have extracted the population estimates for ages 18 to 66. The data series contains the erroneous population estimate. The 2014 Adj column contains the 2014 adjusted to take account of the difference between the 2016 population estimate and 2014 census number of 84,276.

I have selected 2014 because it is the latest year for which the Revenue Commissioners published income tax statistics.
I have selected population numbers aged from 18 to 66 because this group will either be counted as:
1. In employment and registered with the Revenue Commissioners
2. Unemployed and in receipt of some form of allowance or benefit and counted by the Department of Social Protection
3. In third-level education and counted by the Department of Education
4. In second-level education and counted by the Department of Education
5. Not counted in categories 1 to 5
6. Counted in two or more of these categories
and so can be cross-checked with data from the Revenue Commissioners, Department of Education and Department of Social Protection.
There will be errors and double-counting in this data:
• Category 1 will include some people younger than 18 and older than 66.
• Category 2 will also double-count those who are illegally claiming two (or more) forms of unemployment allowance or benefit.
• Category 3 will include students under 18 that are in third-level education
• Category 4 will be small and as the Department of Education do not provide ages of second-level students this number cannot be assessed. I have not attempted to estimate the numbers of second-level students that are 18 (or older).
• Category 5 consists of are people operating entirely in the black market with no engagement with either the Revenue Commissioners or the Department of Social Protection.
• The number in category 6 will include values such as students who are working and those who are working and illegally claiming some form of unemployment allowance or benefit.
The equality between CSO population data and that from the other data sources looks like:

Subject to the errors listed above, the two numbers should be roughly equal.
The intention here is not to produce population estimates that are completely accurate. It is, rather, an attempt to assess the accuracy of the CSO population data using consistency cross-checks from other data sources.
The Revenue Commissioners publish details on income tax payers. The latest year for which this this is available is 2014 – see

According to the Revenue Commissioners, the income earners who are categorised as “Married Couples - Both Earning” or “Married Couples - One Earning” are those who have chosen or have been deemed to have chosen for joint assessment as one tax unit. So each of the 477,603 cases classified as “Married Couples - Both Earning” represents two people.
As the Revenue Commissioners data is from 2014, I will use other data from 2014 as well to provide a uniform view.

The difference in 2014 from population estimates for those aged 18-66 from the CSO and other sources of 664,192 will include the errors listed above.
It is still a large difference.
The arithmetic should be along the lines of:
So, How Many People Actually Live In Ireland? I have no idea. But I strongly believe that it is higher than the number the CSO counted in the 2016 census. For someone with an affinity to numbers, this is both contra-intuitive and disquieting. It could be several hundred thousand more. I do not believe it is 600,000 more or anything like that number.
It is a bit of a mess.
I am sure that I have made errors in this analysis. It was done briefly. Please highlight them.
This analysis has two purposes:
1. A primary one of identifying issues with Irish population statistics and to show that there are real problems
2. A secondary one of attempting to quantify the actual population
I feel that I have achieved both objectives, albeit the secondary one with some major warnings.
There are still unanswered questions, such as:
• How and why could or would people evade being counted in the census?
• What benefit is there of such concealment?
• How could the CSO’s census big count contain such errors and what is the extent of the errors, if any?
• Why is there such a large difference between numbers of PPSNs issued by the Department of Social Protection and immigration as counted by the CSO?
These are valid questions to which I do not have answers. I would welcome comments.
This analysis demonstrates a lack of knowledge and control by Irish governments on population and immigration who do not know what is happening and by those agencies tasked with doing this work.
What Are the likely Impacts And Consequences? There are several sets of possible impacts and consequences relating to resource requirements in areas such as accommodation, transport, health care, legal and justice as well as wider social, societal, political, cultural and economic ones.
In the specific context of property which is the nominal concern of this board, this indicates that demand is being underestimated and supply is even worse than believed. It is possible that a large number of immigrants may leave and so reduce demand for property due, for example, to a combined Brexit/Trump recession and loss of employment. However, unquantified past immigration likely means unquantified future immigration. So the trend for property demand and prices is up.
Knowledge is power and we are powerless.
It may be unfashionable to be seen to question the number of migrants in Ireland. Accusations of xenophobia are all too easily levelled and are just attempts to deflect a valid concern. Like it or not, there are large and popular anti-migrant political parties and social movements throughout Europe and elsewhere that have risen organically because concerns are left unaddressed by established political parties. Wishful thinking is no substitute for analysis. Ignoring a problem will not make it go away. They have already caused seismic changes. Ireland would appear to offer a potential fertile ground for such a party or movement.
Elsewhere I have expressed by view that too much change imposed on a society too quickly causes problems and gives rise to dissent.
