We combine a formula for the energy-dependent parity distribution with a microscopic-macroscopic nuclear level density. This approach describes well the transition from low excitation energies, where a single parity dominates, to high excitations where the two densities are equal.4 pages, 3 figures; contribution to Nuclei In The Cosmos VIII, to appear in Nucl.
