The charged hadron multiplicity fluctuations are considered in the canonical ensemble. The microscopic correlator method is extended to include three conserved charges: baryon number, electric charge, and strangeness. The analytical formulas are presented that allow us to include resonance decay contributions to correlations and fluctuations. We make the predictions for the scaled variances of negative, positive, and all charged hadrons in the most central Pb+Pb (Au+Au) collisions for different collision energies from SIS and AGS to SPS and RHIC.
