Unintentional Injury Death Data Trends for Years 2000-2010 DS 13-13000
Please see the Technical Notes section for complete rate information.
Number of Deaths
The total number of deaths based on the criteria chosen is the numerator.
Total population based upon the specific criteria selected such as the population in a specific sex, race, and age group. Population figures are based on Department of Finance estimates or projections. This is the denominator, and it is known as the population at risk.
Crude Death Rate
Number of deaths divided by the estimated or projected total population. Number of deaths for a specific age group, particular sex, or certain race utilizes the same formula with the appropriate specific group population.______________________________________________
Indicates the average chance of dying, or enables comparison by specific groups over time.
Number of Deaths_______________
Age-Specific Death Rate
Number of deaths in a specific age group divided by the estimated or projected population in that age group.______________________________________________
Compares death rates by age groups at a specific point in time, or an age group over time.
Number of deaths within a specific age group_______________
Population in age group
Age-Adjusted Death Rate
Age specific rates multiplied by their respective 2000 US Standard Population Weight summed to produce age-adjusted rates. ______________________________________________
Removes the potential bias that occurs when the populations being compared have different age distributions and facilitates the comparison of different groups for example counties, race, sex, etc. or over time.
Simple average of numbers.______________________________________________
Point of balance, the preferable measure of central tendency, and represents the greatest stability with further statistical uses.
Sum of thingsmeasured_____________
Total numberof things
Standard Deviation of Population
Age minus the mean age (x). Square the age difference (x2 ). Sum the squares and divide by the total number (N). Calculate the square root.______________________________________________
Tells you how spread out your set of numbers is compared to the mean.
