Transition of the number of deaths and cause of death over the past 110 years, such as "Influenza was the leading cause of death in many deaths"

ByLeo Laporte

A graph that summarizes the changes in the number of deaths and causes of death from 1900 to 2010 is "The New England Journal of Medicine"The facts of interest, such as the fact that the cause of death that could not have been thought in the past has been increasing in recent years, will be visible.

When you visit the site and click the icon under "Interactive Graphic", a separate window opens showing a chart that can be operated interactively. Below, I tried to display such various statistics by touching such a chart.


The graph below shows the trend of deaths in 100,000 people from 1900 to 2010 every 10 years. The graph showing about 1,700 people in the 1900s trailed down until the 1950s, after which it gradually declined and decreased to about 800 in 2010.


The following graph shows the life expectancy immediately after birth, that is, the change in average life expectancy, which shows that the average life expectancy is increasing throughout. However, although the graph is cramped around 1918, the details are described later.


The color of the top 10 causes of deaths in 100,000 people from 1900 to 2010 is as follows. As I looked at it, since there is a big difference in color between 1900 and 2010, I will pick up the cause of death with a big change.


First of all heart disease. In 1900, it was heart disease that was the fourth cause of death, but after that it increased the number of fatalities gradually, it became the number of deaths in 1930 and is ranked first place until 2010.


Looking at the line graph showing the transition of the number of people who died due to heart disease, you can see that it increased at a stretch from 1920 to 1950. About 370 people were kept until around 1970, but gradually it decreased thereafter, and it decreased to about 200 in 2010.


The number gradually rose from 1900, and in 1930 it became the second most fatal cause of death, and keeping that position until 2010 is a cancer that is generally easy to associate with death.


Looking at the line graph, the number of deceased people who died due to cancer gradually increased, peaked in the 1990s, then decreased slightly.


There has been a drastic change in the number of deaths of influenza over the last 100 years. Looking at the graph above, the number dropped at a stretch from 1940 to 50, although it was the top or second cause of death from 1900 to 1920. Although the influenza virus was discovered in 1933, it is predicted that vaccine production is being promoted before that and that the death toll has decreased since 1940 because vaccination has spread to the general level I will. In the graph below the line graph showing the number of deceased people, there are too many fatalities to break through the upper limits of the graph and overflow into the graph above. This was prevalent in the world from 1918 to 1919Spanish coldBy. The number of people infected by Spanish colds is about 600 million people worldwide and the number of deaths is 4000 to 50 million. In the United States, 500,000 people died and 390,000 people died in Japan.


The number of people who died after influenza around 1900 wastuberculosisis. However, it was the first time in the world in 1928antibioticsWas discovered and in 1944Anti-tuberculosis drugHas dramatically decreased the number of deaths since its appearance.


As with tuberculosis, infectious gastroenteritis in which the number of deceased persons was greatly reduced in the first half of the 1900s, but in the present age the number of deceased persons remarkably decreased, and since 1940 it disappeared from the top 10 of the death cause many deaths since 1940 .


The fact that there has not been a big change in the number of deaths since 100 years agoCerebrovascular diseaseis. Cerebrovascular diseases suddenly developing due to hypertension and hyperlipidemia are very difficult to predict and prevent, so there is no drastic change in the number of deaths compared to 100 years ago.


Diabetes is suddenly seen from the 1940's. Although it was not obvious diabetes in the past, as the lifestyle changes, the number of onset has increased and the number of deaths also increased.


The cause of death appearing in the top 10 in 1930 earlier than diabetes mellitus is "traffic accident by car / bike". Popularization of popular cars began in the United States after 1910, and it seems that the number of deaths from traffic accidents has also increased in accordance with that.


Suicide suddenly came into the top 10 in 1990 and 2010. In the United States I returned from Iraq and AfghanistanSoldier's suicide becomes seriousIt is one of the increase of suicide.
