We have used the SDSS DR 4 to study links between starburst and poststarburst galaxies in the redshift range z=0-0.25. Starburst counterparts to the most luminous postbursts seem to be lacking, probably due to an increasing contribution from dust and AGNs. Starburst lifetimes were derived from spectral evolutionary models and space densities and were found to vary with luminosity, from a few times 107 to the order of Gyr at the low luminosity end.
