Population part 2 Flashcards
Factors that cause uneven distribution
Social and historical (Brazil, West of Ireland)
Resources and terrain (Sweden, Dublin City)
Variations in population density through space and time
Population distributed unevenly
Lots of people in some areas, few in others
Population density varies over time
Social and historical factors: West of Ireland
Lower population density than rest of Ireland
Over centuries, population has fluctuated
Before famine:
Population was increasing
Farmers sub-divided land - lots of small farms
Productivity was high, food supply increased - potato
People married young an had large families
The Great Famine: Potato crop failed - blight - cut off main food supply Over 1 million died of starvation Over 1 million emigrated to UK and US Birth rate dropped
After the famine:
Farmers stopped sub-diving land
Younger songs moved away or emigrated to find work
People married later - reduced birth rate
People emigrated as relatives doing well abroad
Population decreased
Population in recent decades in the West of Ireland
Ireland joined EEC (EU) in 1973
–> led to job creation
Séan Lemass encouraged multi-national to invest in the West of Ireland.
Urban areas grew such as Galway but rural areas continued to lose people.
Celtic Tiger helped to create jobs in the West of Ireland
Date of the Great Famine
1845-1852
Social and historical factors: Brazil
Before 1500s: 8 million people Low population density Hunter gatherers Native American population
1500s (Age of Exploration)
Portuguese colonists
Plantations - sugar cane, coffee
Settled along east coast, rapid population growth
High population densities along east coast
Slaves from Africa - racial diversity
1800s-1900s:
Industries began to grow
Cities grew, migrants continued to arrive in cities
1960s:
Government encouraged people to move to interior
Brasilia - new capital city, built 1,000km inland
New roads - Trans-Amazonian Highway, rainforests cleared
People given land, natural resources exploited
Population Distribution in Brazil today
Brasilia is 4th largest city (capital)
it is densely populated
Cities along east coast much bigger
Interior has low population Amazon River Basin --> Hot and humid Heavy Rainfall Dense forests (Difficult to move) Native people forced to leave land
Resources and Terrain - Sweden (reasons)
Climate
Terrain
Resources
Northern Sweden’s climate
Extremely cold climate (winter: -15*C) consisting of Boreal and Tundra climate
Far north of Sweden in Arctic Circle - little sunshine/short days
200 snow days year
Difficult and costly living conditions
Northern Sweden terrain
Snow covered - difficult to move around
Roads are far, and few in between (little amount of roads)
Remote, forested and mountainous
Most life along the coast
Nothern Sweden resources
Many resources - hydro-electricity, timber, iron ore and other minerals
Far from EU markets - makes working of resources difficult and expensive
Minerals exported from Norwegian parts
Central and Southern Sweden: Climate
Cool temperate climate - not a large temp. variation
Good for growing crops - farming
Constant rainfall all year round
Scania in the south is warm enough to grow cereal crops - wheat
Central and Southern Sweden: Terrain
Flag rolling terrain - easy to build roads, rail and urban centres
Malmö, Göteberg and Stockholm - large cities in the south
–> benefit as gateway cities along the Baltic coast
Central and Southern Sweden: Resources
Central Sweden is rich in minerals - iron ore
High quality steel is smelted in CS
–> Used to manufacture ships, cars, trucks, and other engineering products
Resources/terrain/climate: Dublin
Why people live near/close to Dublin
Services:
Banks, shops, etc.
IFSC
Jobs:
Many companies have head offices in Dublin. Eg. google, yahoo, FB
–> corporation tax = 12.5%
Seat of the Government:
Centre of decision making
Route focused:
Rail, roads, air, boat.
Education centre:
Trinity, UCD, DCU
Educated workforce attract large companies
