  In this talk we analyse the claim that supersymmetry (SUSY) naturally
accounts for the observed dark matter density. In many cases, it is necessary
to tune the parameters of a SUSY model to fit the WMAP data. We provide a
quantitative analysis of the degree of tuning required for different
annihilation channels. Some regions are natural, requiring no tuning at all,
whereas others require tuning at the 0.1% level.
