We study the properties of Dirac fermionic dark matter (DM). Present upper limit on the spin-independent (SI) elastic cross sections with nuclei confines the quantum number of Dirac DM to be either I_3=Y=0 or I=0. In this report, we consider the case of I_3=Y=0, but with an arbitrary isospin I. We compare our results with the latest results of the DM relic density measurements, DM elastic scattering off nuclei experiments in the direct search and DM annihilation to SM particles in the indirect search.
