We show quantitatively that the conditions for charge ordering in one-dimensional metals depend strongly on the band filling and the relative magnitudes of intermolecular electronic correlations. We thereby explain the irregular appearance of 4kF charge-density waves in conducting organic charge transfer salts. For band fillings incrementally larger than one-fourth, we predict a new kind of Coulomb-induced defect.
