2.20. One of the most common specific death rates is the age specific death rate. Age specific death rates might be calculated for single years or for decades of age, as 40-49.99 year olds, or for some other interval. ???? Write an expression denoting the age specific death rate for twenty-year-olds in the United States in 1965. m 20 year old = ______________________________________________ × 1000 #### m 20 year old = number of deaths among 20 year old persons in the U.S. in 1965 × 1000 number of 20 year olds in the U.S. in 1965 at midyear ???? Does specific death rate mean age specific death rate?(yes or no) #### No, but age specific death rate is one of the most common forms of specific death rates. 2.21 To denote the length of the age interval, the symbol n is used as follows: m denotes the age specific death rate in persons age x up to but not including x + n. If a ten year interval is desired, then n = l0. If a five year interval is desired, then n = 5. Note that in this expression, x denotes the beginning of the age interval. ???? If the age specific death rate is expressed as 5m10: (1) What is the beginning of the age interval?___________________ (2)What is the length of the interval?__________________________ (3)What ages would be included?__________________________ ### (1) x = 10 years old (2) n = 5 year interval (3) 10-14 year olds would be included. ???? What symbol would denote the age specific death rate for persons in their twenties? ______________________________________________________ #### 10 m 20 Since we are denoting persons of 20 up to 20+10. 2.22 Similarly, this same type of notation is used to denote the number of persons dying between ages x to x + n as n D x · For example, the number of persons dying between ages 60 and 69.99 would be 10 D 60 ???? What symbol could be used to denote the population between ages x to x+n?_______________________________________________ n p x ???? Write the formula for the age specific death rate for persons age x to x+n #### n m x = (( n D x )/ ( n P x )) × 1000. 2.23 The age specific death rate is denoted as: n m x = (( n D x )/ ( n P x )) × 1000 Sometimes one additional symbol is added to this notation. This is the symbol z denoting the year. The age specific death rate for year z is written: n m x z = (( n D x z )/ ( n P x z )) × 1000. ???? Write the age specific death rate for persons in their thirties for 1968. #### 10 m 30 1968 = (( 10 D 30 1968 )/ (10 n P 30 1968 )) × 1000. 9

???? Write the expression for the age specific rate for 25 year olds #### 1 m 25 1968 = (( 1 D 25 1968 )/ ( 1 P 25 1968 )) × 1000 but usually when it is a single year the 1 is omitted. 2.24 In most countries the highest risk of death is in the oldest and the youngest age groups, with minimum risk of death among young adults. ????
