Data post-1991 is available on the website - the data is not directly comparable to this dataset due to definitional issues with the census figures. Housing Stock from 1970 to 1991 does not include vacant habitable residential dwellings.
The most current data is published on these sheets. Previously published data may be subject to revision. Any change from the originally published data will be highlighted by a comment on the cell in question. These comments will be maintained for at least a year after the date of the value change.
