Unit 2A - People and Where They Live Flashcards
Definition of birth rate
The number of live births per 1000 people per year
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
What is GIS?
GIS is a way of storing information about places that makes it easy to compare against other data
What impact does migration have on countries which people leave? Give both positives and negatives
- Population decrease
- Brain drain, often those who leave are the best and brightest, the economically active
+ Remittances (wages) are sent back
What impact does migration have on countries which people go to? Give both positives and negatives
- Have to provide more housing, healthcare and education for bigger population
- Migrants compete for jobs with locals and may cause increased tensions
+ Migrants bring important skills and stimulate the economy
+ Migrants work for lower wages and make factories more profitable
What impact does migration have on the migrants which move country? Give both positives and negatives
- May not speak the native language, lonely, hoemsick, no sense of community
- May feel isolated, cultural differences will be challenging
+ May be eligible for benefits
+ May get a good job and send money home
+ May get better healthcare
+ May get better education

Immigration
From what ages are you considered of working age?
15-65
From what ages are you considered dependant on those of working age?
0-15, and 65+
What can a dependancy ratio tell us about the population of an area?
This will show us the % of the population dependant on the rest of society
How can we calculate the dependancy ratio of an area?
Dependancy ratio = Youth dependant + Age dependant/ working popn x100
Case Study
Describe some of the positive ways in which migration to Germany has benefitted the country of origin, Turkey
+ People leave, pressure off the unemployment rate
+ Remittances, improved economy
+ Workers only spend a few years away, bring money and skills back when they return
+ Reduced pressure on services, allowing the government to concentrate on essential services
+ Migrants who return, increased knowledge, skills, enriching the Turkish population
Case Study
Describe some of the negative ways in which migration to Germany has affected the country of origin, Turkey
- The people who migrate are often the more educated and skilled workers, so the country experiences a ‘brain drain’
- Productivity and innovation declines, as those who are left are less skilled
- Reduction in services, as the economically active are leaving
- Many traditional Turkish people are concerned that the increased global attitude of their people is diluting the Turkish religious beliefs and cultural traditions
Case Study
Describe some of the positive ways in which migration from Turkey has benefitted the destination, Germany
+ Turkish immigrants provided a cheap, skilled workforce, which assisted labour shortage after WW2
+ Increased cheap labour allowed rapid expansion of German manufacturing
+ The Turkish people usually take on jobs that the Germans do not want (Hairdressing, cleaning and driving buses. This provides low cost personal services for the German population
+ Promotes cultural diversity
+Germany has the lowest fertility rate in EU. Migrants are usually younger and will have children, stabilising the BR
Case Study
Describe some of the negative ways in which migration from Turkey has affected the destination, Germany
- In 1967 and 1990, recession led to unemployment. Many Germans lost jobs, Turks remained employed in their lower paid jobs. This fuelled social and ethnic conflict
- More money is spent on translation services, more leaflets are needed in Turkish, students in schools who do not speak German as their first language
- In the early 1990’s a number of racial/ethnic attacks on Turkish people led to concerns over social problems in Germany
- Many migrant workers who lived in Germany wanted citizenship but had to wait a long time
Age groups in a demographic transition model are divided into years of what?
Cohorts, years of five
A demographic transition model (population pyramid) starts at what value?
0, years
The majority of population pyramids will show each cohort as a (blank) of the total population but some will show the (blank) of people within each age category.
