The 1926 Irish Census has been released. Here’s why it’s so important

One hundred years after it was conducted, the first full census of independent Ireland is being released for free online. These nearly 3 million records will be of great significance to Ireland’s population, and a global diaspora of some 80 million claiming Irish ancestry.

As well as providing insight into socioeconomic circumstances following the establishment of Saorstát Éireann (the Irish Free State) in 1922, the 1926 census holds several keys to unravelling Ireland’s complicated past.

For many, this public release will help reconcile the enormous loss caused by the destruction of the Public Record Office of Ireland at the outset of the Irish civil war. An explosion laid waste to over 700 years of Irish historical records, including some of the 19th-century censuses.

In Ireland, public access to historical census returns is legally restricted for 100 years. Almost 16 years since the online release of the 1901 and 1911 household census returns, the demand for more genealogical records is palpable.

So, please be patient with the system (and the wonderful people behind it) as it will be busy. Excitement about previous census releases has crashed websites.

The 1926 census has some novel aspects compared with those conducted under British administration from 1821 to 1911. Although the Irish language was part of a bilingual question since 1851, the 1926 census offered the first opportunity to complete the form as Gaeilge (in Irish).

This census emphasised the “family” as the unit of inquiry, as opposed to the “household”, which was more inclusive of non-relatives cohabiting. As with past censuses, the name, age, sex, marital status/orphanhood, birthplace, language, religion and occupation of each person was documented in terms of their relationship to an appointed head of household.

A census provides the statistical underpinning to plan for future population needs. In the 1920s, the world was reeling from excess young adult mortality – a combination of the first world war and the global influenza pandemic. Ireland was no exception.

Aggregate reports from the 1926 census convey concerns about the declining population, delayed age at marriage and marital fertility.

Perhaps reflecting the remit of the responsible Department of Industry and Commerce (Statistics Branch), the 1926 census sought more precise information than previous censuses about employment and employers. The reports show that of 1,223,014 “gainfully employed” people over the age of 12, 53% were engaged in agriculture.

But regional variations were marked. In Dublin City, heartland of the pejoratively termed “beer and biscuits” economy, that figure was as low as 0.9%. In counties like Galway, agricultural dependency was as high as 75%.

Only 6% of the population was categorised as “unemployed”, most of which was temporary. Some jobs had residential components and, of those, the 14,145 “professed clergymen and nuns” outnumbered the 13,869 non-commissioned members of the recently reduced Óglaigh na hÉireann (Irish army).

The records released on April 18 tell us even more about the men, women and children behind these statistics, what their domestic lives were like, and the parts they played in Saorstát Eireann.

Like many, I approach the release with questions about my own family, such as where my grandparents were at the time.
