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/π 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 ∼ 140 MeV. We present predictions that allow to test the consistency of our results.
