Analyzing Road Accident Data in Delhi
The question asks us to find the number of people who died specifically from head injuries in road accidents that occurred in Delhi during the year 2020. We are given the total number of accidents, the average number of people involved per accident, and two tables providing analysis of those involved.
Step-by-Step Calculation of Fatalities from Head Injuries
To solve this, we need to follow these steps:
- Calculate the total number of people involved in the accidents.
- Determine the number of people who suffered fatalities based on Table I.
- Calculate the number of people who died from head injuries based on Table II.
1. Calculate Total People Involved
We are given:
- Total number of accidents = 10,000
- Average number of people involved per accident = 3
Total number of people involved is the product of the number of accidents and the average number of people per accident.
Total people involved = $10,000 \times 3 = 30,000$ people.
2. Determine Number of Fatalities
Table I provides an analysis of the severity of outcomes for the people involved. It states that Fatalities account for 19% of the people involved.
| Analysis of Severity | Percentage |
|---|---|
| Uninjured | 47% |
| First-Aid Required | 6% |
| Mild Bruises | 9% |
| Hospitalization | 19% |
| Fatalities | 19% |
Number of people who died (fatalities) = 19% of the total people involved.
Number of fatalities = $\frac{19}{100} \times 30,000$
Number of fatalities = $0.19 \times 30,000 = 5,700$ people.
3. Calculate Number of Fatalities from Head Injuries
Table II provides an analysis of the causes of fatalities. It states that Head Injuries account for 69% of the fatalities.
| Analysis of Fatalities | Percentage |
|---|---|
| Head Injuries | 69% |
| Damage to Internal Organs | 21% |
| Fire Casuality | 3% |
| Blood-Loss | 7% |
Number of people who died from head injuries = 69% of the total number of fatalities.
Number died from head injuries = $\frac{69}{100} \times 5,700$
Number died from head injuries = $0.69 \times 5,700 = 3,933$ people.
Therefore, the number of people who died of head injuries in accidents in Delhi during the year 2020 is 3933.
Summary of Results
- Total people involved in accidents: 30,000
- Total fatalities: 5,700
- Fatalities due to head injuries: 3,933

Additional Information: Road Accident Statistics and Severity
Understanding road accident statistics involves analyzing various factors like severity of injuries and causes of death. Table I helps categorize the outcome for every individual involved, ranging from uninjured to fatalities. This helps in assessing the overall impact of road accidents on public health.
Table II specifically looks at the causes of death among those who were fatally injured. This information is crucial for implementing targeted safety measures, such as promoting helmet use (to reduce head injuries) or improving vehicle safety features. Analyzing these percentages allows authorities to understand the most common risks and develop strategies to mitigate them, ultimately aiming to reduce the number of severe injuries and fatalities on the road.
Data analysis from such tables provides valuable insights for road safety policy, emergency medical services, and public awareness campaigns.
