n 1: the condition of having reduced numbers of inhabitants (or
no inhabitants at all)
Bouvier's Law Dictionary, Revised 6th Ed (1856):
DEPOPULATION. In its most proper signification, is the destruction of the
people of a country or place. This word is, however, taken rather in a
passive than an active one; we say depopulation, to designate a diminution
of inhabitants, arising either from violent causes, or the want of
multiplication. Vide 12 Co. 30.
