Missing the North? Why the 1926 Census is 26 Counties Only

IMPORTANT UPDATE: Recent archival research and official statements from NISRA have clarified the status of the 1926 Northern Ireland returns. Please see the revised details below.

The 1926 Census of Ireland is almost live! However, for those of us with roots in the six counties of Northern Ireland (Antrim, Armagh, Down, Fermanagh, Derry and Tyrone), the excitement might be met with a of a “No Results Found” heartbreak.

If you are wondering why your ancestors seem to be missing, here is everything you need to know and how to keep your research moving forward.

One Island, Two Censuses

Following the partition of Ireland and the establishment of the Irish Free State in 1922, the 1926 Census was managed by two separate authorities.

• The 26 Counties (Republic of Ireland): This census was conducted on 18th April 1926. These are the records that have just been released by the National Archives of Ireland.
• The 6 Counties (Northern Ireland): This census was also conducted in 1926, but the individual household forms for the six counties of Northern Ireland are believed to be destroyed during WWII.

Statistical Reports	Available and Searchable	Available (County/General)
Historical Maps	Integrated 1924 OS Layers	Available via PRONI

Northern Ireland’s 1926 Census Reports

While the individual household forms are gone, we are left original census reports. While we can’t see our ancestor’s specific handwriting or their answers, we can see the world they inhabited.

These reports were compiled by clerks in the 1920s who tallied up the data from those now-lost forms. Think of it as a overview of your ancestor’s county.

What the Reports Can Tell Us:

Even without a name, these reports (available here – NISRA website) provide vital context:

• The Religious Landscape: What was the religious makeup of the street? This helps you determine which church records or local schools to investigate next.
• Housing Conditions: The reports detail the ‘quality’ of housing in each townland. You can learn if your ancestor’s area was struggling with overcrowding or if it was a prosperous farming community.
• The Topographical Index: This is a researcher’s secret weapon. It lists every townland, village, and street used in 1926. If you are struggling with a modern map, this index tells you exactly where that “missing” lane was located a century ago.

The ‘Plan B’ Toolkit

Just because the census isn’t available, doesn’t mean your research has to stall. PRONI (the Public Record Office of Northern Ireland) has some incredible alternative records that can bridge the 1911–1926 gap:

1. The 1939 Register

This is perhaps the closest thing to a census for the mid-20th century. Taken at the start of WWII, it lists names, addresses and most importantly exact dates of birth. It’s an essential tool for identifying family members born after the 1911 Census.

How to Request a 1939 Register Search from PRONI

Because these records are not digitized for public browsing, you have to play “detective” by proxy through the PRONI staff. Here is the process:

Step 1: The Preliminary Search

Before you email PRONI, check the PRONI eCatalogue online. You can often find the Reference Number for the specific district or street. Having this information ready makes your application much more likely to be processed quickly.

Step 2: The Application (FOI Request)

To see a specific entry—especially if you believe it is currently “redacted” (closed)—you must submit a formal request.

• Method: You can email proni@communities-ni.gov.uk.
• What to Include: Clearly state you are looking for an entry in the National Registration National Identity (1939 Register). Provide the full name, address, and date of birth of the person you are searching for.

Step 3: Proving “Open” Status

PRONI will only release information on individuals who are:

1. Deceased (and you can provide proof of death).
2. Born more than 100 years ago.

2. Valuation Revision Books

These records are a goldmine for tracking a family’s physical presence in a specific townland. PRONI has digitized many of these. They record changes in land tenancy year-by-year. If your ancestor died or moved, you’ll see their name crossed out (usually in purple or red ink) and replaced with the new tenant. Search the Valuation Revision Books here.

3. Street Directories

For those with ancestors in urban areas like Belfast or Derry, street directories (like Lennon Wylie or PRONI’s digital collection) are published almost annually. They are perfect for confirming that a head of household was still at a specific address in 1926. Search Street Directories here.

Don’t think about the missing records as a dead end; it’s just a detour. Our Northern ancestors left their mark in other ways – in the land they farmed, the churches where they married and the stories they passed down. We may not have their 1926 signature, but we still have their legacy.
