IrishCentral has published an article that will interest many people with Irish ancestry: Irish Ancestry Unearthed - Every Census Since 1926 Online.
However, be aware this article does not contain names and addresses of individual Irish residents. Instead, it is a collection of statistical information.
As stated on the web site:
"In a move that will open up a treasure trove of statistical information, censuses from 1926, 1936, 1946, 1951, 1956, 1961, 1966, 1971, 1979, 1981, 1986, and 1991 are all now just a few clicks of the mouse away.
"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."
