This is a subset of the available data from the 1901 Census of Ireland. The visualization uses a sample of 3,000 records (out of a possible 20,907) of the census returns for females aged 45 to 55 years old who were living in Cork county in 1901. Returns where the occupation was blank or where the total count is less than 3 have been excluded, leaving 1,400 total records displayed in this bar chart. Source: National Archives of Ireland
