Why should you know the reasons people die?

Mortality data is an example that can indicate the number of people dying out for various reasons which can help the authorities in making better decisions about people’s welfare and allocation of resources. It plays an important part in designing healthcare systems as well as improving the data collection systems in countries.

Once the reason and daily counting of death are logged into the statistics systems, the policymakers can begin work towards preventing the deaths and treating severe health conditions such as COVID-19. To standardize the data collection and processing of the statistics, WHO has consolidated the international classification of diseases (ICD-11).

This is an improved data platform that enables timely and accurate data related to the causes of death as well as health information conforming to international standards.


Understanding the health conditions and diseases that pose the highest risk to Indians can help us in purchasing health insurance policies that can cover these diseases while also predicting the life expectancy in a realistic way which can help policyholders plan their term life insurance plans.
