Definition of death rate
The number of deaths per 1000 people per year
Definition of natural increase
When the birth rate exceeds the death rate
Definition of natural decrease
When the death rate exceeds the birth rate
How to calculate the natural change of a population
BR - DR = Change
Births per 1000 people - Deaths per 1000 people = Natural increase/decrease of (blank) per 1000 people
Describe stage 1 of the demographic transition model
High BR
High DR
Population growth is slow
Population is small
Describe stage 2 of the demographic transition model
High BR DR falls Better healthcare, food, water Improved economy Rapid population growth, population explosion begins
Describe stage 3 of the demographic transition model
Better education
BR starts falling
DR low
Population growth slows
Describe stage 4 of the demographic transition model
BR low
DR low
Population longevity
Population remains high but growth is slow, even decreasing at certain points due to an extremely low BR
Give an example of a country in stage 2 of the demographic transition model
India
Give an example of a country in stage 3 of the demographic transition model
Brazil
Give an example of a country in stage 4 of the demographic transition model
USA
Europe
UK, etc
What does ‘GIS’ stand for?
Geographical Information Systems
Give an example of an online geographical information system that compares information
NINIS
Website NI
Give an example of some of the information presented on the NINIS system
The NINIS stores lots of information about:
Immigration to certain areas
Wealth distribution
Housing distribution
What are the advantages of GIS?
Allows access to a lot of information quickly and easily
It is easy to identify patterns in maps and tables displaying the stored information
Lots of information on one area/location can be found on one site (e.g. NINIS)
The information has already been accumulated and is up to date
Definition of migration
When people move house/location permanently
Definition of migrants
People who move house/location
Definition of immigration
When people move into a country/area
Definition of emmigration
When people leave/exit a country/area
