While many are now familiar with the value of the 1901 and 1911 censuses for family history, less use has been made of these documents for social history and population studies. Great excitement was created when the censuses were made available free online through the good offices of the Irish government and the people of Mumbai in India who transcribed them for us at no great expense. Now the department of heritage proposes to make the 1926 census available by again outsourcing the work to a far country. However, we will have to wait until 2026. How much more excitement there is for some places where the 1821 census survives. This is the case with Birr and the entire barony of Ballybritt.
