The Tools of a Stellar "Demographer"

I will present various techniques for taking

a stellar "census" of the unresolved stellar component

in galaxies.  I will end the discussion by describing

some applications for stellar population analysis, which

hopefully will demonstrate why one would even care about

star "demographics" in a galaxy.  For example, I will

demonstrate how knowledge of the stellar population

within a galaxy can give critical information regarding

galactic dynamics, kinematics and/or clues to galaxy

formation and evolution.
