Death rates in the 20th century
Death Rates in the 20th Century is the ratio of deaths compared to the population around the world throughout the 20th century. When giving these ratios, they are most commonly expressed by number of deaths per 1,000 people per year. Many Factors contribute to death rates such as cause of death, increasing the death rate, an aging population, which could increase and decrease the death rates by birth rates, and improvements in public health, decreasing the death rate.
According to the CIA World Factbook, as of July 2012, the global crude death rate is 7.99 deaths/1,000 population.〔(【引用サイトリンク】url=https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html )〕 The crude death rate represents the total number of deaths per year per thousand people. Comparatively, the crude death rate in the year 1900 was 17.2 deaths/1,000 population and 9.6 deaths/1,000 population in 1950 in America.〔(【引用サイトリンク】url=http://www.infoplease.com/ipa/A0005131.html )〕
