Mortality

Question 1

What are the 2 components of Mortality?

Answer 1

1. Lifespan: the oldest age to which a human could possibly survive (122 yrs max, population average 85 yrs)
2. Longevity: how long people on average actually live (biological & social factors)

Question 2

What does CDR stand for? (MEASURING MORTALITY PT 1)

Answer 2

Crude Death Rate

Question 3

What is the Crude Death Rate Equation? (MEASURING MORTALITY PT 1)

Answer 3

CDR = (# of deaths/total population) x 1000

Question 4

Crude Death Rate advantages?/

Answer 4

useful measure of mortality’s contribution to change in the size of the population

Question 5

Crude Death rate disadvantages?

Answer 5

• CDR influenced by pop. age structure

- Not everyone is at equal risk of dying (higher rates at certain ages)

Question 6

What does leO stand for? (MEASURING MORTALITY PT 2)

Answer 6

Life Expectancy at Birth: the average # of years of life remaining for a newborn person, assuming they are subject to the current age-specific death rates.

Question 7

What is the most effective tool for measuring mortality? (MEASURING MORTALITY PT 2)

Answer 7

Life Expectancy at Birth (leO), calculated from life-tables, best for comparing mortality levels of population with different age compositions

Question 8

What does IMR stand for? (MEASURING MORTALITY PT 3)

Answer 8

Infant Mortality Rates

Question 9

What is the equation for Infant Mortality Rates? (MEASURING MORTALITY PT 3)

Answer 9

IMR= (# of deaths to children/ total live births) x 1000

Question 10

What does infant mortality reveal compared to CDR and leO?

Answer 10

• Life expectancy tied to IMR
• Critical pop health indicator
• IMR also reflects health of the mother
• -High IMR indicates general health problems among adults as well
