What was a result of large population and why?
epidemic disease
Because large populations had a higher population density –> high mortality
How did epidemic diseases come to be?
They came from domestic animals that later evolved into diseases that affect humans
When did Industrial Revolution begin?
17th century
What as the result of the Industrial Revolution?
mass-production of industrial and consumer goods
What were the 3 pros and cons of the Industrial Revolution
Cons –> negative impacts on the environment
Pros –> populations increased, less people were working on the land, and death rates dropped
What is the importance of geographic location
It determines whether you can live a agricultural lifestyle if its suitable for plants and animal species largely
Difference between the epidemic and pandemic
Epidemic –> affects a country
Pandemic –> affects the world
Population Explosion
a sharp decrease in infant mortality and we’re living longer. We also have access to many more resources
Demography
the study of human population
Fertility Rate
the number of children each women has
What is happening to the fertility rate?
It is continuing to fall and will reduce the population size over time
What is a Demographic Transition Model
4-stage model that describes the relationship between the economy and how it affects population
What factors affect growth rates?
- geographic location
- differences in age structures of the population
What are the ultimate main factors that influence population growth?
birth & infant death rates
What causes population growth to decrease?
When a society becomes industrialised and eocnomically secure
What is the trend for Stage 1 in the Demographic Transition Model
- high death rates
- high birth rates
- low total population
What is the trend for Stage 2 in the Demographic Transition Model
- lower death rates
- high birth rates
- higher total population
What is the trend for Stage 3 in the Demographic Transition Model
- low death rates
- low birth rates
- higher total population
What is the trend for Stage 4 in the Demographic Transition Model
- low death rates
- low birth rates
- higher total population
Gross National Product (GNP)
It is the total value of all goods and services produced per year per capita.
What does the Gross National Product tell us
it is used as an index of a country’s level of industrialisation.
What is the correlation between industrialised countries and life span
People in industrialised countries have longer life spans
What is the correlation between life expectancy and growth rates
Populations with a high life expectancy (how long someone is expected to live) have some of the lowest growth rates in the world.
What is happening to the total world food population?
It has increased dramatically but per capita, production is now declining.
