Less attention has been paid to the distribution of crime across households, though this is crucial in determining optimal distribu- tion of limited policing resources in pursuing the aim of distributive justice. The writers have previously demonstrated that in England and Wales the distribution of crime victimisation has remained pretty much unchanged over the period of the crime drop. The present paper seeks to extend the study of changes in the distribution of victimisa- tion over time using data from 25 countries contributing data to the International Crime Victimisation Survey (ICVS) sweeps (1989–2000). While fragmentary, the data mirror the trends discerned in England and Wales. The trends are not an artefact of the inclusion of particular countries in particular sweeps. The demographic, economical, geographi- cal and social household characteristics associated with victimisation are consistent across time. The suggested policy implication is the need for greater emphasis on preventing multiple victimisation.

A recent paper (Ignatans and Pease 2015a) showed The intention here, insofar as the data permit, is to that the crime drop in England and Wales in recent years examine whether the trends identified in England and was greatest in absolute terms for the most victimised Wales extend beyond its borders. Is the slight increase in households, but not so great relative to the decline of inequality of distribution of crime evident in England and crime generally as to yield a more even distribution of Wales also evident elsewhere?
