Irish censuses from before 1901 have not generally survived to the present day, due to a combination of official incompetence (the 1881 and 1891 returns were pulped before they could be transcribed into books), non-retention (1861 and 1871), and a fire during the Irish Civil War in 1922. The 1901 and 1911 censuses for Ireland (all of which was then part of the UK) have been available for inspection since 1960 – they were made available earlier than the other British records, since Irish law is different on this matter. No census was taken in 1921 due to the disruption of the Irish War of Independence. The first census taken in the Irish Free State (now the Republic of Ireland) was in April 1926; the first Northern Ireland census occurred at the same time. No census took place in Northern Ireland in 1931.
