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 ...
Crude mortality rate refers to the number of deaths over a given period divided by the person-years lived by the population over that period. It is usually expressed in units of deaths per 1,000 individuals per year. The list is based on CIA World Factbook 2023 estimates, unless indicated otherwise.
In developed countries, starting around 1880, death rates decreased faster among women, leading to differences in mortality rates between males and females. Before 1880, death rates were the same. In people born after 1900, the death rate of 50- to 70-year-old men was double that of women of the same age.
The birth rate is 11.0 births/1,000 population, as of 2020. [82] This was the lowest birth rate since records began. There were 3,613,647 births in 2020, this was the lowest number of births since 1980. [82] 11.0 births/1,000 population per year (final data for 2020). 11.4 births/1,000 population per year (final data for 2019). [82]
The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths.

Within 20 years, many countries in those regions will face a situation of the largest population cohort being those over 65 and the average age approaching 50. In 2100, according to research led by the University of Washington, 2.4 billion people will be over the age of 65, compared with 1.7 billion under the age of 20. [19]
Percentage of the population over 65 in Europe in 2020 Population pyramid of the European Union in 2023 Europe population pyramid from 1950 to 2023. The ageing of Europe, also known as the greying of Europe, is a demographic phenomenon in Europe characterised by a decrease in fertility, a decrease in mortality rate, and a higher life expectancy among European populations.

The Social Security Administration (SSA) estimates that the dependency ratio (people ages 65+ divided by people ages 20–64) in 2080 will be over 40%, compared to the 20% in 2005. [91] SSA data shows one out of every four 65-year-olds today will live past the age of 90, while one out of 10 will live past 95.
