  We use the statistical hadronization model (SHM) to describe hadron
multiplicity yields and fluctuations. We consider
  200 GeV Au-Au collisions, and show that both event averaged yields of stable
particles and resonances, and event-by-event fluctuation of the $K/\pi$ ratio
can be described within the SHM using the same set of thermal parameters,
provided that the phase space occupancy parameter value is significantly above
chemical equilibrium, and the freeze-out temperature is $\sim 140$ MeV. We
present predictions that allow to test the consistency of our results.
