Computed population of cataclysmic variables at the current epoch in the M₂‐P_orb plane for our standard model (see Table 1). Here M₂ is the mass of the donor star. The color represents the logarithm of the number of systems in a particular M₂‐P_orb cell, of which there are 100 per 0.1 M_⊙ and 100 hr⁻¹ interval in P_orb. The color scale is given on the right‐hand side of the figure.
