Population distribution and density is uneven in Dublin

North Dublin

North Dublin has a low population desnity because much of farmland in North Dublin is used for market gardening - supplies apcuty with fresh fruit and vegetables.

Dublin airport is also located here and prevents Dublin City from sprawling north

1

Population distribution and density is uneven in Dublin

South Dublin

The Dublin mountains prevent the city from expanding south.

Settlement is almost completely absent in mountains - exposed to strong winds and winter frosts.

2

Population distribution and density is uneven in Dublin

Dublin city

High population density

city centre has many multi-story apartment blocks

high density terraced housing - Drumcondra

during the day, people travel into city for work

3

Population distribution and density is uneven in Dublin
expansion

expands westwards and towns such as tallaghr and clondalkin have grown as a result

4

Low population density can lead to..

1. Low marriage rates

2. Abandonment of land

3. Economic and political isolation

5

Low population densities: West of Ireland

Low marriage rates

Before 1930s - matchmakers arranged marriages
--> guaranteed eldest son a wife

Matchmakers declined in Ireland.
--> girls emigrated to Britain
--> girls with a secondary education went to Dublin to work as teachers, civil servants, etc.

Women did not like idea of staying on a small, poor rural farm

Bachelor farmers grew in the West
--> reduced when free education came in during 1960s

6

Low population densities: West of Ireland

Abandonment of land

Farms very small
--> difficult to make a living

Many farmers' children now have third level education
--> can gain jobs in areas other than agriculture

Small farms in west now used for forestry, tourism, etc.

7

Low population densities: West of Ireland

Economic and political isolation

Peripheral location of the west means it is far away from markets.
(Dublin, EU)

Infrastructure
-Underdeveloped
-Unattractive for industry

Fewer employment opportunities

8

Low population densities: Mali

Low marriage rates

Agriculture is very difficult - young men look for work in cities

Marriage rate falls - low birth rates

9

Low population densities: Mali

Abandonment of land

Desertification makes agriculture impossible
-high temperatures
-overgrazing
-lack of rainfall

This causes rural-urban migration
--> land is abandoned

10

Low population densities: Mali

Political and economic isolation

Mali is land locked - goods must be transported by land through other countries

Companies find it difficult to invest

Infrastructure underdeveloped

11

High populationdensity: Kolkata

India - 1 billion people
Kolkata (Calcutta) - 14 million people

Rural-to-urban migration

People move to cities to find work and better services

12

Problems in Kolkata

Overcrowding:
Shanty towns called bustees
Homes made of cardboard, metal, wood, plastic

Pavement dwellers:
Many migrants live on streets

Lack of open space:
Bustees expanding into country side

Poor sanitation:
Sewage pipes overflow and contaminate water supply

Lack of clean water:
Shortage of clean water in bustees
Spreads diseases

13

Low population densities: Hong Kong

Colony of Great Britain until 1997

Population density - 6,300 per km2

Wealthy region - industrial sector

Land not suitable for living on

14

Problems in Hong Kong

Overcrowding:
Limited available land
Intensively used - cramped conditions

Shortage of clean water:
Pressure on water supply
Water polluted by sewage and waste

Pollution:
Overcrowding leads to noise and air pollution

High rise buildings:
Eyesore + blocks out light

Lack of open space:
Land reclaimed from sea (polders)
Shortage of open space in CBD
Little sunlight
