Question 73: To ask the Taoiseach his views on the fact that the Central Statistics Office cannot provide a breakdown of emigration on the basis of age, especially the numbers emigrating between the ages of 18 and 30 years; his views on whether such data should be collected and disseminated in view of the importance of this issue; and if he will make a statement on the matter.

Question 74: To ask the Taoiseach if there are any plans by the Central Statistics Office to collect data on emigration on a more regular and current basis in view of the fact that the most recent data published by the CSO was published in September 2010 and only covered the period from April 2009 to April 2010; and if he will make a statement on the matter.

I propose to take Questions Nos. 73 and 74 together.

The principal source of information for the estimation of annual migration flows, incorporating both emigration and immigration, is the Quarterly National Household Survey, which classifies the flows by sex, broad age group, origin and destination, and nationality. The figures are published on an annual basis in September of each year, so the next publication in September 2011 will cover the period April 2010 to April 2011. Because of the underlying seasonality and variability of all migration flows the CSO does not publish the data on a sub-annual basis. The estimates will be assessed and subject to review once the definitive results of the five yearly census are made available in 2012.
