  In this talk we discuss the constraints on supersymmetry arising from data
from a number of recent experiments. There appears to be good cumulative
evidence from experiment in favor of positivity of the sign of the Higgs mixing
parameter $\mu$. Implications of this result for Yukawa unification are
discussed since Yukawa unification is sensitive to the $\mu$ sign. An analysis
of dark matter under the constraints of Yukawa unification is also given. It is
shown that the simultaneous imposition of all existing constraints sharply
defines the parameter space of models. Specifically models with nonuniversality
of gaugino masses provide a simple resolution to the positivity of the $\mu$
parameter and Yukawa unification. Implications of these results for colliders
and for the next generation of dark matter searches are also discussed.
