Abstract:
    A summary of global properties and an evaluation of the equilibrium
    state of molecular regions in the outer Galaxy are presented from the
    decomposition of the Five College Radio Astronomy Observatory (FCRAO,
    see 1998ApJS..115..241H) Outer Galaxy Survey and targeted ^12^CO and
    ^13^CO observations (at 115GHz) of four giant molecular cloud
    complexes. The ensemble of identified objects includes both small,
    isolated clouds and clumps within larger cloud complexes.
