\Mal*thu"sian\, a.
Of or pertaining to the political economist, the Rev. T. R.
Malthus, or conforming to his views; as, Malthusian theories.
Note: Malthus held that population tends to increase faster
      than its means of subsistence can be made to do, and
      hence that the lower classes must necessarily suffer
      more or less from lack of food, unless an increase of
      population be checked by prudential restraint or
      otherwise.
