An epidemiologic survey of roller-skating accidents in Funville, CA a city with a population of 100,000, produced the following: 1. Number of skaters in Funville during any given month: 12,000 2. Roller-skating accidents in Funville: 600 3. Total number of residents injured from roller-skating: 1,800 4. Total number of deaths from roller-skating: 90 5. Total number of deaths from all causes: 900 What is the cause-specific mortality rate (from roller skating) in Funville?

Answer 1

The mortality rate due to the roller skating is 10%

Explanation:

Given:

Population of the city = 100,000

Number of skaters in Funville during any given month = 12,000

Roller-skating accidents in Funville = 600

Total number of residents injured from roller-skating = 1,800

number of deaths from roller-skating = 90

Total number of deaths from all causes = 900

Now,

The cause-specific mortality rate (from roller skating) in Funville

=
`\frac{\textup{Total number of deaths from roller-skating }}{\textup{Total number of deaths from all causes}}*100\%`

=
`\frac{\textup{90}}{\textup{900}}*100\%`

= 10%

Hence,

The mortality rate due to the roller skating is 10%
