This article traces the power of numbers in discourses relating to homeless
ness in Britain. It argues that enumeration has played a formative role in
the recording of homelessness as a 'problem', and in the public policy resp
onse to homelessness in specific locations. In particular, the use of rough
sleeper counts as popular defining representations of the problem of, and
response to, homelessness is analysed in terms of their wider pivotal signi
ficance in political and policy discourses relating to homeless people. The
article concludes that how rough sleeper counts are undertaken has clear d
istorting consequences for the identification and understanding of to what
extent, where, and among whom homelessness represents a pressing social iss
ue. Discursive valorisation of enumeration needs to be interconnected criti
cally with other more qualitative forms of knowledge drawing on the experie
nce of housing officers, local agency workers and others dealing with local
ised homelessness on a day-today basis.
