Dr. Tom Boland:

It is snowballing. We put up posters in places where unemployed people are likely to be, asking them to contact us if they would like an interview, so it is akin to stopping people in the street. We also work with the Irish National Organisation of the Unemployed, INOU, to ask whether it can put out a mailshot to its members. Of course, that skews the information to certain people. There is a well-known effect whereby people do not contact you for an interview unless they have something to say, so there may be a degree of skew to that.
