Only fragments of the 1851 census of Ireland are known to survive, and most such fragments are for County Antrim, in the north. However, a little-known census fragment for County Cork also survived the destruction of the Public Record Office in 1922, and it is here transcribed and published for the first time. It deals exclusively with the parishes of Kilcrumper and Kilworth in County Cork and parts of Leitrim and Macroney in the Union of Kilworth. The entries for the parishes of Kilcrumper and Kilworth appear to be inclusive of all of their townlands; however, the records for Leitrim would appear to omit four townlands and the Macroney entries refer to only five of the parish's sixteen townlands. The census records themselves are arranged by household, just as they appear in the original.
