1901 and 1911 Census

For the purpose of genealogical research the two earliest available complete census reports are those of 1901 & 1911.


From 1821 a census was carried out every ten years. Unfortunately, a large amount of this material was destroyed in 1922, some was pulped for paper during World War I and some destroyed by government order.


The 1901 Census was arranged by county, district electoral division and townland. It gives detailed information relating to all persons, including householders and their dependents, residents of army and R.I.C. barracks, convents, hospitals, and other institutions, similar to present day censuses.

The headings used in the 1901 Census included the following:

  • Name and Surname
  • Relation to Head of Family
  • Religious Profession
  • Education
  • Age
  • Sex
  • Rank, Profession or Occupation
  • Marriage
  • Where Born
  • Ability to speak Irish.

In addition to the above, the 1911 Census had additional columns to record the following:

  • Number of years married, if applicable.
  • Total Number of Children born alive.
  • Children still living

Ages of adults are to be treated as suspect, with most adults actually being older than they admitted.

Details concerning the houses were also given; such as the number of rooms occupied by each family, type of roof, and number of windows.

We have computerized both the 1901 and the 1911 Census for Co. Sligo.
