6
Q

A
When in the population the birth rate is greater than the death rate
7

What is natural decrease
A
When in the population the death rate is greater than the birth rate
8
Q
What is the population cycle
A
Also known as the demographic transition model
The changes in the population in the population cycle are influenced by the state of the country and its economy
9
Q
Stage 1 - high fluctuating
A
Birth rate; high Death rate; high Natural increase; slow increase Reason for changes; undeveloped economy, wars, famines and disease E.g. Rainforest tribes
10
Q
Stage 2 - early expanding
A
Birth rate; remains high Death rate; falls rapidly Natural increase; very rapid increase Reason for changes; better economy, improved medical care, water supply and sanitation E.g. Mali, Kenya, Nigeria
11
Q
Stage 3 - late expanding
A
Birth rate; falls quickly Death rate; falls much slower Natural increase; increases but slowly Reason for changes; stronger economy, good health care, people live longer E.g. Venezuela, Brazil, Mexico
12
Q
Stage 4 - low fluctuating
A
Birth rate; low Death rate; low Natural increase; very slow Reason for changes; developed economy, later marriage, low birth rate, more women working outside the home E.g. USA, Ireland, Italy, Sweden
13
Q
Stage 5 - senile stage
A
Birth rate; very low Death rate; low Natural increase; possible decrease Reason for changes; developed economy, birth rate lower than death rate, population may fall slightly E.g. Germany
14
Q
How does food affect population change
A
- good food leads to healthy population
- famine leads to population decline e.g. Ireland 1m died 1m emigrated population
Fell from 8m to 6 1/2 m between 1845-51 - Brazil made new technology to increase the amount of food supply e.g population grew from 72m - 100m
15
Q
How does health affect population change
A
- better medical care and supplies
- longer lives
- Ireland improved housing better medical care and new drugs reduced deaths caused by TB from about 147 per 100,000 in the 1940s to 24 per 100,000 people in the late 1950s
- Germany did the same
- Brazil child mortality high in 1980s because of infectious diseases caused by poor sanitary conditions. Improved public health, vaccinations, increased prosperity have reduced the child mortality rate
16
Q
How does technology affect population change
A
- improved farm machinery
- new fertilisers and pesticides
17
Q
How does war affect population change
A
- 20th century Germany had 2 wars reducing its population greatly the population fell from 67m to 62m
Since young men were killed marriage rate was slower
18
Q
How does education affect population change
A
- better school systems
- more skilled workforces
- attracts industry
- encourages migrants to work for both countries
19
Q
What is the pessimistic view
A
That there will be a world population explosion and a rapid increase in population using up the earths resources
20
Q
What is the optimistic view
A
Population growth will slow down as countries become developed therefore more resources Smaller families Food supply increase New technology intensive and productive farming
21
Q
What is a census
A
A population count to get information on the population structure Providing Age Education Sex Religion Accommodation
22
Q
What are population pyramids
A
Population pyramid shows the age and sex structure of a country
23
Q
What are the uses of population pyramids
A
- Compare the stage of economic development
- compare dependent sector ( under 15 over 65) with working sector (economically active 15-65)
- death,birth rate and natural in/decrease
- plan for building schools and hospitals and nursing homes
- Local population structure to plan for future needs
24
Q
How to compare pyramids
A
- Germany a developed countries pyramid would be even
* Brazil a developing countries pyramid would be wide at the base and thin at the top
25
What does Ireland's population pyramids say
Evenly shaped
High % of working population, support The dependent
Women have a longer life expectancy
26
Case study : west of Ireland population density over time
1) pre-famine - rising population: rose before the great famine and densely populated with early marriage
2) famine - declining population: crop failed, starvation and disease, emigration
3) after the famine - gradual decline in population: later marriages, less crop, emigration continued
4) economy improves - increase: 1960-70s multinational corporations, more jobs
27
What is population density.
The average number of people per squares kilometre
28
What is population distribution
The location and spread of where people live, describing where the population is dense and sparse

44
Altitude and relief
Altitude refers to the height above sea level, while relief refers to the shape of the landscape

Towns were built on dry-point sites
| Some towns were built at the lowest crossing point of the river e.g. Cork and Dublin
46

Poor land quality, whether marshy, boggy or stripped of soil, does not encourage settlement

A linear pattern of statelet
Farmhouse were clustered together
49
Urban settlement

We're needed to limit any built up development to the randstad and to maintain a green hearts
