For sociologists, genealogists or any member of the 70 million-strong Irish diaspora around the world, this development could provide a huge amount of valuable information about the development of Ireland and its people.

The censuses contain standard data like population and valuation of each area, occupation, religion and birthplace, housing, ages, orphanhood, and conjugal conditions, industrial status, Irish language, dependency, and general report.

Over the years, however, new sections were added. In 1946, a volume on the fertility of marriage was introduced. In the 1961 census, a volume on “Occupations of Males and Females in each Province, County, County Borough, and in each Town of 5,000 and overpopulation” was recorded and published in 1963, and in 1971, the census started compiling a section of information called “usual residence, migration, and birthplace."

As the years pass, the statistics reveal the forces behind the emergence of what is modern Ireland. If you want to find out something about someplace or someone in Ireland during this 80+ year period, there is no better place to start digging.
