The crude death rate is defined as "the mortality rate from all causes of death for a population," calculated as the "total number of deaths during a given time interval" divided by the "mid-interval population", per 1,000 or 100,000; for instance, the population of the United States was around 290,810,000 in 2003, and in that year, approximately 2,419,900 deaths occurred in total, giving a ...
French 16th-/17th-century ivory pendant, Monk and Death, recalling mortality and the certainty of death (Walters Art Museum) [citation needed] While "brain death" is viewed as problematic by some scholars, there are proponents of it [who?] that believe this definition of death is the most reasonable for distinguishing life from death. The ...
The Gompertz–Makeham law of mortality describes the age dynamics of human mortality rather accurately in the age window from about 30 to 80 years of age. At more advanced ages, some studies have found that death rates increase more slowly – a phenomenon known as the late-life mortality deceleration [2] – but more recent studies disagree. [4]
A short period of excess mortality that is followed by a compensating period of mortality deficit (i.e., fewer deaths than expected, because those people have died at a younger age) is quite common, and is also known as "harvesting". Mortality deficit in a particular time period can be caused by deaths displaced to an earlier time (due to ...
Perinatal mortality (PNM) is the death of a fetus or neonate and is the basis to calculate the perinatal mortality rate. [1] Perinatal means "relating to the period starting a few weeks before birth and including the birth and a few weeks after birth."
As such, mortality is often inaccurately measured using either prospective demographic surveillance or retrospective mortality surveys. Prospective demographic surveillance requires much manpower and is difficult to implement in a spread-out population. Retrospective mortality surveys are prone to selection and reporting biases.
Under 5 mortality rates: Number of child deaths within the 5th birthday divided by total number of births. [9] Child Mortality refers to the premature deaths of any child under the age of 5 years old. However, within those 5 years, there are 5 smaller groups. Perinatal refers to a fetus, a living organism, but not yet born.
Infant mortality rate by region Life expectancy at birth by region. The infant mortality rate correlates very strongly with the likelihood of state failure, and is among the best predictors thereof. [115] IMR is therefore also a useful indicator of a country's level of health (development), and is a component of the physical quality of life index.
