High birth rates & high death rates. Zero or low growth- -2. Declining death rate, but high birth rate, so high growth rate -3. Declining death rate, and birth rate, so low growth rate /4. Both birth and death rates low, so close to zero growth- –

Why is population momentum an important concept for countries concerned about population growth in the future?
As certain age groups get older, populations must garner the necessary resources to cater towards these predicted booms and busts in population size, and the age groups that dominate the total population.

Why do scientists speak of a demographically divided world?
– One half of the population is comprised of industrialized countries. These countries have established a balance between births and deaths, which improves the average citizen’s living conditions.- In the other half, birth rates remain high, and rapid population growth is leading to the prevalence of environmental degredation and the lowering of the standard of living.
Define:Crude Birth RateCrude Death RateCrude Rate if Natural Increase
– Crude Birth Rate = # of live births/1,000 people (estimate at midyear)- Crude Death Rate = # of deaths/1,000 people (estimate at midyear)- Crude Rate of Natural Increase = CBR-CDR

How can the absolute number of births increase if the birth rate is declining?
Must take into account the population (of women).

It’s a issue of proportion.

Why is the CDR a poor measure to compare the health of a population?
It is too affected by the age structure of a population.- Non-proportional
Name one way to prevent malaria.
– Bednets- Antimalarial drugs
What s the intervention that prevents polio and measels?
The sum of cause-specific death rates in a population gives us what rate?
Mortality Rate
What is the shape of the ASDR?
Nike swoosh upwards.
Name one public health intervention that led to declines in mortality.
Water cleaning, which halted the Cholera outbreak.

In what region is maternal mortality the highest?
Name one continent where endemic polio is still found.
Name 3 intermediate fertility variables.
– Formation & dissolution of sexual unions- Exposure to intercourse within unions- Abstinence & Involuntarily abstinence- Celibacy
Define the TFR.
Number of children that would be born to a woman is she were to live to the end of her child bearing years, and bear children abiding by current ASFRs.
