As a general feature, the IMF is well described by a power-law form for $m\\ga 1 \\msol$ and a lognormal form below. The extension of the disk IMF into the brown dwarf (BD) regime is in good agreement with observations and yields a disk BD number-density comparable to the stellar one $\\sim 0.1 \\pc3$. The IMF of young clusters is found to be consistent with the disk field IMF, providing the same correction for unresolved binaries.
