An ionic model and the total-energy method are used to calculate the density and distribution of carriers in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} systems and, in particular, to understand the relationship between the density of carriers and the density of oxygen vacancies in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}}. It is shown that the density of carriers is normally 1{minus}{ital x} per unit cell and the carriers are holes on the oxygen ions in the CuO{sub 2} planes. In addition, for the 1+ valence copper ions Cu{sup +} present in the CuO{open square} plane, the density of Cu{sup +} is normally {ital x} per unit cell.
