If you’ve been wondering “when was the last census in Ireland,” you’re not alone. Many people search for this when trying to understand population changes, plan for services, or simply satisfy their curiosity about how Ireland is evolving. The answer is straightforward: the most recent census took place on **Sunday, 3 April 2022**.
What Exactly Is the Census and Why Does It Matter?
Every five years, Ireland carries out a full census of the population. It’s organised by the Central Statistics Office (CSO) and gives us a detailed snapshot of who lives here — how many people, where they live, their ages, jobs, education levels, housing situations, and much more. This information helps the government plan schools, hospitals, roads, and public services for the years ahead.
The 2022 census was particularly significant because it showed Ireland’s population had crossed the five-million mark for the first time since the 1850s.
Key Details of the 2022 Census
Census night was **Sunday, 3 April 2022**. Everyone who was in the country that night — including visitors and those temporarily away from home — was counted. Forms were delivered to every household, and people could complete them on paper or online.
Here are some of the headline findings released in 2023:
- Total population: **5,149,139** — an increase of 8.1% since 2016.
- First time the population exceeded five million since 1851.
- Average age rose to 38.8 years.
- Significant growth in urban areas, especially around Dublin.
- Increased diversity in nationality, religion, and languages spoken at home.
Why Was the 2022 Census Delayed?
Originally planned for 2021, the census was pushed back a year because of the COVID-19 pandemic. Health and safety concerns made it impossible to carry out the usual door-to-door work on the original schedule. The extra year actually allowed for some improvements, including better online options.
How Does Ireland’s Census Compare to Previous Ones?
Ireland has a long tradition of census-taking. The last full census before 2022 was in 2016. Going further back, the 1926 census (the first after Irish independence) has been big news recently — its records were released to the public in April 2026, exactly 100 years later. Many families have been digging into their grandparents’ and great-grandparents’ details from that era.
| Census Year | Population (approx.) | Notes |
|---|---|---|
| 2016 | 4.76 million | Strong recovery period |
| 2022 | 5.15 million | First over 5 million since 1851 |
| 1926 | 2.97 million | First Free State census |
When Is the Next Census in Ireland?
The next one is scheduled for **2027**, with Census Day expected around early May 2027. For the first time, households will have a proper online completion option alongside the traditional paper forms. This should make things smoother and more accessible for everyone.
Why People Search for Census Information
Besides general curiosity, people look up census dates for genealogy research, academic projects, business planning, or to understand demographic shifts. Whether you’re tracing your family tree or just want to know how Ireland has changed, the census data is incredibly valuable.
