Population estimates at the level of County are produced by the Central Statistics Office every five years as part of the Census. Between Census years, annual population estimates are only produced at the level of Regional Authority. My Department produces estimates of the numbers of social housing units which are occupied on the last day of each year at the level of Local Authority. This data is available on my Department’s website at:

A table showing the population at end April 2011 and April 2016 from Census outputs, the numbers of social housing units occupied at the end of the prior year and the ratio between the two variables has been added to my Department's website at the same address.
