Cause Of Death Bar Graph Visual Definition
A “Cause of Death Bar Graph” is a visual representation that uses bars or strips to compare and contrast different types of data, frequencies, or other measures of distinct categories of data. In the context of causes of death, this type of graph can be used to display and analyze mortality data.
The bars in the graph represent different causes of death, and their lengths or heights correspond to the frequency or rate of deaths due to each cause. This allows for a clear comparison of the impact of different causes of death within a population.
uch a graph can be used to display data in various ways. For example, it can show the number of deaths for each cause in a single year, or it can show trends over time by displaying the number of deaths for each cause in each year over a period of time.
The data used to create these graphs often comes from official statistics agencies or health organizations. For instance, the Institute for Health Metrics and Evaluation provides a “Causes of Death (COD) Visualization” tool that allows users to examine more than 350 causes in both adjusted and pre-adjusted numbers, rates, and percentages for 204 countries and territories.
In Canada, the government provides an interactive web application that shows the change in a cause of death by age at the time of death since the year 2000. The data can be viewed by the number of deaths, the percentage of deaths, and the age-specific mortality rate per 100,000 population.
These visualizations can provide valuable insights into public health trends and can inform policy decisions. However, it’s important to note that the data used to create these graphs can sometimes be subject to delays or revisions. For example, deaths under investigation by coroners or medical examiners, such as suicides, accidents, and homicides, often require a lengthy investigation.
In conclusion, a “Cause of Death Bar Graph” is a powerful tool for visualizing and understanding mortality data. It allows for a clear comparison of different causes of death and can reveal important trends over time. However, the data used to create these graphs must be interpreted with care, taking into account potential delays or revisions.
