N: 1. mid-14c., “condition of being mortal,” from Old French mortalite “massacre, slaughter; fatal illness; poverty; destruction” (12c.), from Latin mortalitem (nominative mortalitas) “state of being mortal; subjection to death,” from mortalis (see mortal (adj.)). Meaning “widespread death” is from c.1400; meaning “number of deaths from some cause or in a given period” is from 1640s.
2. mortality, in demographic usage, the frequency of death in a population.
In general, the risk of death at any given age is less for females than for males, except during the childbearing years (in economically developed societies females have a lower mortality even during those years). The risk of death for both sexes is high immediately after birth, diminishing during childhood and reaching a minimum at 10 to 12 years of age. The risk then rises again, until at late ages it surpasses that of the first year of life.
