The report breaks things out better:<p><a href="http:&#x2F;&#x2F;www.bjs.gov&#x2F;content&#x2F;pub&#x2F;pdf&#x2F;hb9411.pdf" rel="nofollow">http:&#x2F;&#x2F;www.bjs.gov&#x2F;content&#x2F;pub&#x2F;pdf&#x2F;hb9411.pdf</a><p>Table 5 sort of shows what I was getting at, burglaries of lower income households dropped a lot more than burglaries in general. One explanation of that is that lower end break ins aren&#x27;t worth it anymore.<p>If that is the case, the average would go up without the rest of the burglaries really changing.<p>(I guess that could be described as a change in the distribution of burglaries rather than a shift in the distribution; I read your reply here as pointing to a shift)
