SUMMARY:What did we learn about the Milky Way during the last decade\,
  and what shall we learn using Gaia and LSST?\, Astronomy Colloquium\,
  Zeljko Ivezic\, University of Washington
DESCRIPTION:Studies of stellar populations\, understood to mean collec
 tions of stars with common spatial\, kinematic\, chemical\, and/or age
  distributions\, have been reinvigorated during the last decade by the
  advent of large-area sky surveys such as SDSS\, 2MASS\, RAVE\, and ot
 hers. These data\, together with theoretical and modeling advances\, a
 re revolutionizing our understanding of the nature of the Milky Way\, 
 and galaxy formation and evolution in general. These recent<br><br>
\n
 developments have made it clear that the Milky Way is a complex and dy
 namic structure\, one that is still being shaped by the merging of nei
 ghboring smaller galaxies. I will review the progress over the last de
 cade\, and will briefly discuss new breakthroughs expected from Gaia a
 nd LSST surveys\, which will improve measurement precision manyfold\, 
 and comprise billions of individual stars.<br><br>
