Editing Mortality rate (section)

==Crude death rate, globally==
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 death (mortality) rate of 832 deaths per 100,000.<ref name="cdc.gov"/>{{rp|3–20f}} {{As of|2020}}, the [[Central Intelligence Agency|CIA]] estimates the U.S. crude death rate will be 8.3 per 1,000, while it estimates that the global rate will be 7.7 per 1,000.<ref name=CIA2020/>

According to the [[World Health Organization]], the ten leading causes of death, globally, in 2016, for both sexes and all ages, were as presented in the table below.<ref>{{cite web| author = WHO Staff | date=2018|title=Global Health Observatory (GHO) data: Top 10 causes of death|location = Geneva, CH | publisher=World Health Organization | url=https://www.who.int/gho/mortality_burden_disease/causes_death/top_10/en/| archive-url=https://web.archive.org/web/20140808230640/http://www.who.int/gho/mortality_burden_disease/causes_death/top_10/en/| url-status=dead| archive-date=August 8, 2014| access-date = January 31, 2020}}</ref>

Mortality rate is also measured per thousand. It is determined by how many people of a certain age die per thousand people. Decrease of mortality rate is one of the reasons for increase of population. Development of medical science and other technologies has resulted in the decrease of mortality rate in all the countries of the world for some decades. In 1990, the mortality rate of children under five years of age was 144 per thousand, but in 2015 the child mortality rate was 38 per thousand.{{cn|date=July 2021}}
