the.com/morbidity

means The rate or proportion of illness, injury, or disease in a population, as distinct from the death rate.

from From Latin morbidus, 'diseased,' rooted in morbus, 'disease' or 'sickness' — a word of uncertain deeper origin, though some link it distantly to a root meaning 'to die' or 'to waste away.' English borrowed 'morbid' in the 1600s for anything diseased or unwholesome, and later spun off 'morbidity' as the clinical measure of how much disease exists in a given group — the quiet statistical cousin to 'mortality,' tallying suffering rather than death.
