Flashcards in Population part 2 Deck (15):

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


Factors that cause uneven distribution

Social and historical (Brazil, West of Ireland)

Resources and terrain (Sweden, Dublin City)


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



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

Industries began to grow
Cities grew, migrants continued to arrive in cities

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)



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

Banks, shops, etc.

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
