mortality rate
A statistical measure that indicates the ratio of deaths to the total population over a specific period of time. It is often referred to as the mortality rate.
Die Sterblichkeit bei dieser Krankheit konnte durch neue Medikamente deutlich gesenkt werden.
The mortality rate for this disease was significantly reduced through new medications.
The word is derived from the adjective 'sterblich' (mortal), which in turn comes from the verb 'sterben' (to die). The ending '-keit' is a typical way of forming an abstract noun from an adjective that describes a quality or state.
Die Unsterblichkeit ist ein alter Traum der Menschheit.
Immortality is an ancient dream of humankind.
You can often recognize the statistical meaning from numbers, percentages, or words like 'Rate' (rate), 'hoch' (high), 'niedrig' (low), 'sinken' (to fall), or 'steigen' (to rise). The philosophical meaning is usually connected with topics such as life, death, art, or religion.
Die Sterblichkeit in der Altersgruppe über 80 Jahren ist gestiegen.
Mortality in the age group over 80 has increased.
In a statistical context, 'Sterblichkeit' (mortality) is often combined with certain verbs and adjectives. Typical phrases are 'hohe/niedrige Sterblichkeit' (high/low mortality) and 'die Sterblichkeit senken/reduzieren' (to lower/reduce mortality).
Das Land hat eine sehr hohe Kindersterblichkeit.
The country has very high child mortality.
In the philosophical sense, the word is often used in fixed expressions. Common combinations are 'sich mit der Sterblichkeit auseinandersetzen' (to confront mortality), 'sich seiner Sterblichkeit bewusst werden' (to become aware of one's mortality), or 'die menschliche Sterblichkeit' (human mortality).
Er begann, sich nach dem Tod seines Freundes mit seiner eigenen Sterblichkeit auseinanderzusetzen.
After his friend's death, he began to confront his own mortality.
life expectancy
'Lebenserwartung' and 'Sterblichkeit' are both used in statistics about life and death. But they do not mean the same thing. 'Lebenserwartung' says how many years people are expected to live on average. 'Sterblichkeit' says how many people in a group or within a period of time die. Learners may confuse the words because both often appear in texts about health, population, or medicine. Put simply: with 'Lebenserwartung', you think of years of life; with 'Sterblichkeit', you think of deaths.
Nach der Einführung der neuen Behandlung sank die Sterblichkeit deutlich.
After the introduction of the new treatment, the mortality rate fell significantly.
In vielen Ländern ist die Lebenserwartung in den letzten Jahren gestiegen.
In many countries, life expectancy has risen in recent years.
