Fertility Flashcards
How do populations change?
The Demographic Balancing Equation:
POPULATION = FERTILITY+MORTALITY+MIGRATION
What does it mean to be a global citizen?
The idea that you are one among many.
As of Sept. 28, 2012– What was the US population? The World?
US Pop. 314 million
World Pop. 7 billion
What does a demographic transition model traditionally describes?
A population tends to progress through as it moves from high mortality and fertility rates to low mortality and fertility rates.
What is the general World reaction to global population policy?
- Most countries have a population policy
- 5 international population conferences
- assumption that population growth is automatically/economically bad.
What are the 2 related meanings when you hear the word Fertility?
1) The # of births occurring to an individual woman
2) The # of births occurring in a population
What does Fecundity mean?
the physiological capacity to produce children
What does Fertility mean?
the actual reproductive behavior of a woman, a couple, of a population.
Why measure Fertility? (2 purposes)
- Population Additions: asses the relative # of ppl added to a population in a given time
- Behavioral Differences; asses childbearing behavior for otherwise similar women in different populations.
What do Rates measure?
Measures used to convey the # of events occuring out of the # “at risk” of such an event during a specific period of time.
What does CBR stand for?
Crude Birth Rate
What is the Crude Birth Rate equation? (MEASURING FERTILITY PT1)
CBR = (# of births/ total population) x 1000
CBR advantages (MEASURING FERTILITY PT1)
- good for looking at fertilit’s contribution to population growth
- ok for comparing populations
CBR disadvantages (MEASURING FERTILITY PT1)
-not a good basis for comparing behaviors because it ignores age and sex structure of a population
What does TFR stand for?
Total Fertility Rate- the average number of children the women in a population will have over their lifetime if exposed to the currently prevailing age-specific fertility rates.
