People doing Irish research are special people! They have great patience and if they find census information unavailable for a particular year they are resourceful and look for substitutes for the missing information.
The 1901 and 1911 census have been available online for some time.
There is some good news for Irish researchers! More resources are available online – and access is free!
In the last while I have read articles from Dick Eastman on April 29 and FamilySearch on 1 May announcing the availability of new records online. The release of these records is the result of a joint project between the National Archives of Ireland, FamilySearch and FindMyPast. Here is the link to the press release 29 April on the FindMyPast website – you are encouraged to go to that site as there is helpful information, graphics, and a video – as well as a link for free access to the records!
