Demographics of Sloan Digital Sky Survey galaxies along the Hubble
  sequence
  We present the statistical properties of a volume-limited sample of 7,429
nearby (z = 0.033 - 0.044) galaxies from the Sloan Digital Sky Survey Data
Release 7. Our database includes morphology distribution as well as the
structural and spectroscopic properties of each morphology type based on the
recent re-measurements of spectral line strengths by Oh and collaborators
(2011). Our database does not include galaxies that are apparently smaller and
flatter, because morphology classification of them turned out to be difficult.
Our statistics confirmed the up-to-date knowledge of galaxy populations, e.g.,
correlations between morphology and line strengths as well as the derived ages,
etc. We hope that this database will be useful as a reference.
