3.7 & 3.9 Flashcards
3.7
Birth or death rate
how many births or deaths within a population
3.7
Crude birth or death rate
How many births or deaths out of 1,000 in a population
Does not take into affect age in gender so not a realiable source
Formulas
(number or birth or death per year/ total population ) x 100
Birth or death rate
3.7
(# of birth or death per year/ total population) X 1000
Crude birth or death rate formula
3.7
Total Fertility rate
TFR
avg. number of children a woman in a population will bear throughout her lifetime
3.7
Replacement Level Fertility
the TFR required to offset deaths in a pop. and keep pop. size stable
Developed 2.1 rate (Replace momma and papa)
3.7
Infant mortality
IMR
Hows does this correrate to TFR
number of deaths of children under 1 year per 1,000 people in a pop.
Higher IMR + High TFR
3.7
Development (Affurence)
more developed, or wealthy nations have a lower TFR than less developed nations
Reason can be
- Women are more educatied
- more econmincal oppertuites
- Later age of preganacy
- Childern aren’t need to do labor
3.7
what is Double time (Rule of 70)
The time it takes (in years) for a population to double is equal to 70 divided by the growth rate
3.7
70 / % of growth rate =
Doubling time
3.9
What are the stages of Demographyc Transition
Preindustrial
Industrializing / Developing
Industrialized / Developed
Post-Industrialized / Highly Developed
Post-Industrialized / Highly Developed
3.9 Stages
Preindustrial
- High TFR and IMR
- Not much growth bc CBR and CDR and practial the same
No countries are here
3.9 Stages
Industrializing / Developing
- IMR and CDR decrease
- TFR stay high bc of lack of education, childern needed to work, and takes time for society to change
- Rapid growth bc of high CBR and low CDR
ex Guatemala
3.9 stages
Industrialized / Developed
- TFR declines bc women get more job offers, delay for marriage and childern, and education about everything
- Slow growth rate
- CDR is catchin up to CBR bc CBR drops
ex India and Mexico
