Ireland, Census, 1901

What is in This Collection?

In this 1901 Irish census, Ireland was not only interested in the people living in their country, but also any visitors. The government also wanted to know what religions they were. In this census, farms and businesses were also detailed.

The 1901 and 1911 Censuses are the only surviving censuses for the country of Ireland after the Irish Civil War bombing on 30 June 1922, when a massive explosion and fire demolished the building and the other records.

Additionally, there are other Irish genealogy records that have survived, such as:

  • Civil registrations
  • Parish registers
  • Baptism, marriage, and burial records for Roman Catholics, Presbyterians, and Methodists
  • Griffith’s valuations (land records)

Additional records and/or images may be added to this collection in the future.
