Testing the Census Reports
A warning that testing had not been carried out is included in my famine index page.

On this page you will find my tests and comments on the Census Data compared with
other information which is available, and follows my tests on the
of the Census Data and the report of 1856, and recorded on my internal consistency
page. You may usefully read that before reading this page
 

EXTERNAL CONSISTENCY

The Census Data not only has internal inconsistencies, but also conflicts with:
* successive history books, such as "The Great Hunger"
* Contemporary accounts

For consistency, I will use "The Great Hunger" [TGH] as a reference, and make specific reference where
other material is used.

A. Total Population

"And assuming that emigration was equal to the immigration" - this from the 1851 Census Report and commenting on a time of the greatest exodus from Ireland that ever occurred.
Alan Gailey,"Rural Housing in Ulster in the Mid-Nineteenth Century"  part 'B' "Facts from Gweedore -comments on Memorial of Patrick McKye, schoolteacher in 1837 i. .. There is (sic) about 4000 persons in this parish" comments that " This is an error: the population in 1841 was 9,049"  ISBN 0 337 23127 3
[TGH] : Ch 1: p31: "An intelligent relief officer wrote that the Census of 1841 was 'pronounced universally to be no fair criterion of the present population'.  He had it tested in Co Clare and found the population to be one third greater than had been recorded;"   Captain Wynne I.O. Clare, to Secy. Public Works, December 5, 1846. CSO Registerd Papers SPO Dublin, 1391
Commons Papers 1847, Vol 14, on Captain Wynne's letters 26th November 1846, regarding the impartiality of relief committees:
"It appears, indeed, from the evidence of Captain Wynne himself, that both the letters above referred to were written in the hurry and excitement of much business; that they conveyed a meaning much wider than he intended, and that if time had permitted, or if he had supposed that they would be published as formal and official documents, he would have written in a more careful and guarded manner" - March, 1947. Captain Wynne's evidence shows that he "sold out" of the army and was first employed by the Government in Co Clare on 28th October, 1846.

Commons Papers: Census report for 1841, published 1843? : comments that the 1841 figures were of an improved accuracy from what had gone before. The census takers were mainly the Royal Irish Constabulary, and that the previous census takers were paid on the number of forms returned. The returns were subject to checks and balances, though what these were is not stated.

There are two issues here: the accuracy of the overall totals, and how accurately the figures model the state of the population.
The accuracy of the overall totals is questioned elsewhere, and I will not trouble the reader with the mathematical distortions necessary to create the illusion of a "Holocaust". It is clear from the quotations above that Captain Wynne was dealing with an extraordinary situation, and assessed the population about five weeks after arriving in Co Clare. It seems, from the text quoted above, that Captain Wynne's letter of December 5, 1846, was written " in the hurry and excitement of much business," and that he was incorrect in stating that the "pronouncement" was "universal",

Therefore, not only is there doubt regarding the accuracy of Captain Wynne's statement, it is not clear whether the statement applies to some locations within Co Clare, to Co Clare in its entirety, or to all of Ireland.  The importance of his statement lies not in its overall view of the size of Ireland's population in 1841 or 1851 (assuming the statement was meant to apply to all of Ireland,) but more in its implication for other statistics, especially rates of birth. However, there appears to be no confirmation from other sources, no indication of the size of population sampled, and no statement on the methods used. Without these, no objective assessment of the truth of the matter can be made.
 

[THG] Ch 1 p31: "therefore in 1845 when famine came the population might well have been above nine millions."
This appears to be a subjective assessment based on the above text and the writer's assessment of population change.

I have no _evidence_ that the population in Ireland in 1845 was above 8.2 millions, and no _evidence_ that Ireland's population distributions were anything other than those shown in the Census data. There is, therefore, little point in speculating what population changes might have taken place, other than to say that errors of less than +/- ten percent in gross populations will have little impact on any conclusions drawn.
 
 

B. Births
[TGH] Ch 1 p30 "Girls married at sixteen, boys at seventeen or eighteen, and Irishwomen were exceptionally fertile;'... for twelve years 19 in 20 of them breed every second year"

[TGH} Ch1 p31 "For this closely packed and rapidly increasing people"

The Census Data of 1841 indicates that births were barely able to keep up with deaths, emigration, and migration, and the population profile given by the 1841 data indicates that fertility was falling, and had fallen since 1835.
 

C. Deaths

[TGH] Ch1 p31: "They were warm, they were abundantly fed - as long as the potato did not fail"
 
 

Illustrated London News , 3 April 1852: " it has consigned upwards of one million of human beings - some accounts say upwards of two millions- to a premature death by famine and fever."
This account may have an echo in the later [1856] Census Report, however, the census data does not support that statement. It records : "mortality for the last five years of the decennial period upon which it is our duty to report was as great as 985,366, or very nearly one million." and  "But no pen has recorded the numbers of the forlorn and starving who perished by the wayside or in ditches".

[TGH] "Between 1845 and 1851 at least one million people died from starvation or famine-related diseases"

There is no way that the numbers recorded [ over 20,000 persons] as dying from starvation can be reconciled with the above statements. There are reports of large numbers of people dying from disease, but there are few reports of death by starvation. The figure of 985,366 inlcludes death by natural causes, though natural causes in those days came close to famine related diseases. The Illustrated London News report allows us to view the famine in Ireland through English eyes, however, the lack of a reference guiding us to "some accounts" makes the report  worthless in the pursuit of verifiable facts.
 
 
 

D. Emigration and Migration
"and a further one million people emigrated."
[TGH] Ch12,  p239, " No disaster comparable to Grosse Isle occurred in the United States"
