A number of measures indicate the viability of a nation' s economy  The level and rate of growth of aggregate output are the most significant indicators, but unemployment and inflation rates are also important  Further, Switzerland, Austria, Israel, Ireland, Denmark, and Finland all have viable economics, but none has a very large population
Switzerland and Austria each have populations of about seven million; the other populations are at least one-fourth smaller
A nation's population affects the level and rate of growth of aggregate output more than it affects unemployment and inflation rates.
