Drawing on our recent experience of fieldwork in north London, this pa
per considers the relative merits of different kinds of focus group, c
omparing groups composed of comparative strangers with 'natural' group
s whose members are already acquainted with one another. The consequen
ces of different recruitment strategies are assessed in terms of the g
roup dynamics to which they give rise. Each method has its own strengt
hs and weaknesses which should Ire calculated in relation to the objec
tives of the research.
