Results for the Galactic distribution of shell-type SNRs are obtained, using empirically derived correction factors to account for selection effects. The spatial distribution has a peak 4-6 kpc from the Galactic center, and is shown to resemble that obtained by Johnson and MacLeod (1963) for spiral galaxy SN. Using the Cox (1979) model, an average SNR age of 6800 yr is found with about 50 percent uncertainty. Constraints are placed on the SNR birthrate which are consistent with the SN rate. 24 refs.
