Population Flashcards
Why are there fewer people in mountainous areas
No farming Hard to build infrastructure and houses Generally colder and wetter Landslides or avalanches Isolated
Definition of population
Density of people in a certain area (total population/total area of land)
Reasons for Glasgow and Edinburgh being populated areas
Near large rivers Glasgow important for ship building Water for power Coal found close Fertile land Jobs available Scottish government in Edinburgh
Reasons for population distribution
High temperatures Lots of rain Dense forest Unpleasant living conditions Fertile soil Flat land Resources for industry
Where in continents is population concentrated
Edges not middle
Most crowded continents
Europe and Asia
Population distribution in India separate
High relief is lower and flat land is higher
Importation and exportation available in South so population is higher here
Dense population in industrial areas and sparse in woods/forest
Population distribution in India overall
Dense in South
Sparse in the centre, Far East, far north and North East
Birth rate definition
Number of babies born per thousand people per year
Death rate definition
Number of people who die per thousand people per year
Natural increase definition
Difference between the birth and death rate- birth rate must be higher than death rate for natural increase
Natural decrease definition
Difference between birth and rate- death rate must be higher than birth rate for natural decrease
Young population on jobs
Low unemployment
Demographic transition model stage 1
Why high birth rate?
High birth rate because
Population growth is stable
Parents needed children to look after them in old age
Lack of contraceptives
Sometimes you’d get more land with more children
Demographic transition model stage 1
Why high death rate?
High death rate because Lack of medical help High disease rate Close living conditions Lack of sanitation Lack of clean water
Society and population growth in DTM stage 1
Subsistence farming, agricultural society
Population growth is stable
Demographic transition model stage 2
Why high birth rate?
Help for farming and care in old age Continue family name Girls not accepted Contraceptives not easily obtainable More people overall to have children
Demographic transition model stage 2
Why lower death rate?
Better sanitation and hygiene
Water clean
Improved education
More medicine and readily available
Society and population growth in DTM stage 2
Farming still dominated society with close living conditions and an increasing population but death rate is high but decreasing
Demographic transition model stage 3 Why high (falling) birth rate?
Accepting of contraception Children can no longer work-expense People married later Women became more independent Pensions in production
Demographic transition model stage 3
Why low birth rate?
Fewer women dying in child birth
Society and population growth in DTM stage 3
Population aren’t dependant on farming and most people are working on manufacturing industry and some in service industry
Demographic transition model stage 4
Why low birth rate?
- all previous reasons
- abortions introduced into societies
- pensions introduced
- women expect careers so decide on children and later in life
- single lifestyle becoming more accepted
- marriage without immediate children accepted
- homosexuality more common
Demographic transition model stage 4
Why low death rate?
- huge improvements in medicine
- healthier lifestyles
- high education
Society and population growth in DTM stage 4
Most people employed in service industry
Demographic transition model stage 5 predictions
Low birth rate and death rate because children are expensive and older population- not enough young people to work
What is a population pyramid
A graph which shows the structure of a countries population in age and gender
Shape of population pyramid in LDC DTM in stage 1
Triangle point at top at 60
Shape of population pyramid in LDC DTM in stage 2
Larger triangle (tip 80)
Shape of population pyramid in LDC DTM in stage 3
Straight then triangle on top (80)
Shape of population pyramid in MDC DTM in stage 4
Curved flat at top
Consequences of a high birth rate
- large % of young people
- growing population
- can lead to overcrowding
- low education because too many kids
- can outstrip resources eg land
