ch 2 : Notes
· Demography:
· The world population exploded after the black death.
o This was largely because a lot more food could be grow.
o Scientist discovered bacteria
o A lot of little things came together to grow the population.
· Developing country’s are having more babies then developed countries.
· Japan went out with 300 scientist and copied the American and European way of industry.
· Infant mortality rate: number of deaths within a thousand births that die in a year.
· Birth rates go down during the great depression and during times of low economic growth.
· Birthrates also went down in the 1960’s because people wanted to have different life style choices.
· Crude Birth: Number of live births per one thousand of live births .
· Natural Increase rate:
o In the year 200 the natural increase rate is 1.4%
o That means the that every 50 years there will be a natural increase
· Over Pop: When the population overgrows the resources that it can get.
· In 1989 Canada had a net gain of 87m people
· High natural increase rates tend to be clustered around the world.
o When there are a lot of people in one place then the it will have a higher rate of natural increase
· Total fertility rate: on average the number of children per child bearing women. (women: 15 – 49)
o Has come down a lot since 1980
o Total fertility rate thinks that the rate of fertility will not change over time.
o It also looks at individual women and not society as a hole.
§ Foe example we know that Hispanic women tend to have more children the other people.
o Global average right now is 3
o People that are more settled tend not have as many babies.
o Went down by 50% in Bangladesh
§ One man decided that he would loan money to people in groups of five.
§ Worked very week and charged 20% tax’s
§ They have a loan repayment rate of 98% which is 25% higher then America
§ Ultimately he convinced people that women should be working and not just making babies.
o In Europe it around 5 in one thousand : which is considered very good.
o In the USA it is around 6.05 which is very good, Europe is considered the gold standard though.
· The significance of life expectancy:
o For a baby born today in the united states 78
o Which is 51 st in life expectancy
· There used to be more young people then older people.
· But no a days the population isn’t a pyramid but a rectangle.
· Population has grow largly because of the diffusion of medical products.
· Population is also going up because more babies are being born safly and healthily. Population going down when people start to make more money.
· There are five stages of population growth:
o 1: pre-modern
o 2: industrializing
o 3: mature industrial
o 4: past industrial
o 5:
· If countries have a lot of dependent people then country has a lot of weight to carry.
· Sex ration: number of makes to number of females
o In Europe and North American there are 95 males for every 100 females
o In the rest of the world there are 102 males for ever 100 females.
o There are more men in places like : oil rigs , gold mines, ect.
· Population falls during a famine
o People die of starvation
o Birth rates go down during a famine
o People tend to leave famine stricken places
· Every ten years there is a senses that counts everyone and gets information about the people
o immigrants tend to get under reported.
§ The door to door people go from property to property not from house to house.
o The government bases program on the senses but the senses is usually not correct.
· Most of the population growth in the world took place in the second half of the 20th century.
o This happened because of the different stages that other countries were in.
o Lowering death rate grow the population very fast.
o As country’s become wealthier they tend to produce less babies
· How to stall population growth
o Textbook: birth control
· Micro finance
o Tiny loads to groups of people
· Malfus :
o Predicted the population will grow so much that we can’t feed everyone.
o He did not think about advanced machines and new technologies
· Green revulsion: selected breeding and using more chemicals to make the plants grow.
· Natural increase : In demographics, the rate of natural increase (RNI) is the crude birth rate minus the crude death rate of a population. If we neglect the migration, then a positive RNI number means that the population increases and a negative number means that the population decreases.
o Use birth control to decrease
o Being educated to decrease
· Demographic transition model: The Demographic transition (DT) used to represent the transition from high birth and death rates to low birth and death rates as a country develops from a pre-industrial to an industrialized economic system. ...
o When women become income earners the population growth goes down
· Four stages of health transition
o 1. Feminine and epidemics
o 2. Receding pandemics
o 3. Age of degenerative and man made disease
o 4. age of delayed degenerated diseases
