The number of persons who have died in a given period of time and within a specified population size.
The number of deaths per year per thousand of population.
The number of deaths within a group of people in 1 year divided by the average or midyear population of that group. If total population is used, the result is called the crude death rate. Death rate can also be calculated for the population within certain age groups; the result is the age-specific death rate. Death rate may be measured in people with a specific disease or condition, such as a gunshot wound (homicide rate) or heart disease.
The death (mortality) rate is the number of deaths per 100,000 — or sometimes 10,000 or 1,000 of the population per year. In 2007, when the population of the UK was nearly 61 million, of whom about 11.3 million were of pensionable age, the death rate was 9.1 per 1,000 population.
The number of deaths in a specified population, usually expressed per 100,000 population, over a given period, usually 1 year.
