- examples:
- US, Europe, Japan
-
what are the qualities of moderately developed countries?
examples?
- medium evel of industrialization
- higher birth rates
- higher infant mortality rates
- shorter life spans
- lower avg. GNPs

-
What are the qualities of less developed countries?

Demographic transition
4 stages that shows how industrialization affect pop. size
-
what happens during stage 1 of demographic transition?
- pre-industrial stage
- high birth rate (high IMR)
- high death rate
- low pop. growth
-
what happens during stage 2 of demographic transition?
- transitional stage
- industrialization
- more food availability
- more health care
- birth rate stays high
- death rate begins to fall
- population grows quickly
-
what happens during stage 3 of demographic transition?
- industrial stage
- birth rate falls to near death rate
- better jobs and education for women
- decline in IMR
- pop. growth rate continues, but is low
-
what happens during stage 4 of demographic transition?
- post industrial stage
- birth rate falls more
- birth rate = death rate
- ZPG (zero pop. growth)
- birth rate declines more and becomes less than death rate = negative pop. growth
- unsustainability
- very few countries
-
Infant Mortality Rate
# of babies per 1000 that don't make it to the 1st year
-
replacement level fertility
# of kids that a couple should have to replace both parents
-
What is the avg. # of kids that a woman will have in her reproductive years?
examples of some countries?
- about 0 - 5 + of kids
- Pakistan = 4.6 TFR
- UK = 1.6 TFR
- US = 2.1 TFR
