The Department uses various means to examine graduate mobility. Overall emigration rates are estimated by the Central Statistics Office (CSO) and reported in their migration estimates publications, published on the CSO website. In some cases these estimates are available broken down by level of education and by age group, but these estimates do not report on specific graduate cohorts at the level of individual area of study or by qualification level. The latest overall figures show the inward number outweighs the outward. A key resource for understanding graduate mobility is the Graduate Outcomes Survey administrated by the Higher Education Authority (HEA). This survey is distributed to all graduates of higher education institutions nine months after graduation. Respondents report whether they are engaged in employment or further study and whether this is within Ireland (including Northern Ireland) or overseas. Data is published by the HEA on their website (www.hea.ie).
