Computed population of cataclysmic variables at the current epoch in the ﹩R_{2}- P_{\mathrm{orb}\,}﹩ plane for our standard model (see Table 1). Here R₂ is the radius of the donor star. The color represents the logarithm of the number of systems in a particular R₂‐P_orb cell, of which there are 100 per 0.1 R_⊙ and 100 per hour interval in P_orb. The color scale is given on the right‐hand side of the figure.
