Carried out by Church of Ireland clergymen, this census takes account of the numbers of both Catholics and Protestants in each parish in the Diocese, to varying degrees of thoroughness. Whilst some parishes will record simply the numbers present in each area, others will have named the heads of each household. The Census was taken throughout the country though the results for only four Dioceses – Cork & Ross, Waterford, Armagh and Cashel & Emly – survive. Tipperary Studies holds paper copies of the originals from the National Archives.
