Population Density
By Shiv Mirpuri
Introduction
• Population density is an often reported and commonly
compared statistic for places around the world.
• It is commonly represented as people per sq. km. ( or sq.
mile ).
• Total area population / land area in sq. km. ( or sq. mile)
• Density within a country can vary dramatically depending
on geographical and economic factors so pop. density is
only a raw gauge to measure a population’s
disbursement across the land.
• About 90% of the earth’s people live on 10% of the land.
Largest Countries
Country Population ( 000
people )
Area ( 000 km2⃣) Population density
( people / km2⃣)
Brazil 153,725 8,512 18
Canada 29,248 9,971 2.9
China 1,208,841 9,561 126.4
Russia 147,997 17,075 8.7
USA 260,650 9,809 26.6
These are the five largest countries and economies in the world.
Their population densities vary greatly.
China’s Population Density
• Pop. density is 126.4 people per sq.
km.
• Most populated country in the
world.
• 4th biggest country in the world.
• The western and northern parts of
China have a few million people,
while the eastern half has about 1.3
billion, the vast majority living in
major cities.
China’s Population Density
China’s Population Density
• Population is most sparse in the
mountainous, desert and grassland
regions of the northwest and
southwest.
• The south-west is home to the
harsh Tibetan Plateau which leads
to the Himalaya Mtns. The high
altitudes and harsh cold
temperatures in the winter, make
this one of the least populous
areas in the world.
Himalaya Mountains
China’s Population Density
• Flowing out of the Tibetan Plateau
are two of China’s longest rivers,
the Yangtze and the Yellow River.
They cut across China as they
continue towards the east coast
through the more densely
populated areas.
• About 20% of China’s land is
desert. The largest deserts are the
Gobi and the Taklamakan Desert in
the north-west. These areas are
sparsely populated due to their
arid environment and harsh winter
climate.
Gobi Desert
Russia’s Population Density
• Pop. density is 8.7 people per sq.
km. making it one of the most
sparsely populated countries in
the world.
• World’s largest country and has a
very diverse geography.
• Forests cover some 40% of the
entire Russian land mass.
• Many mountain areas e.g the Ural
Mtns, the Caucasus Mtns and the
Altai Mtns in the south.
Russia’s Population Density
Russia’s Population Density
• Siberia- scarsely populated area
covered by coniferous forests,
swamps and tundra in the north-
extreme climate
• Pop. most dense in the western
part of the country ( North
European Plain ), centering
around Moscow and St.
Petersburg.
• 74% of pop. is urban.
Kremlin in Moscow
USA’s Population Density
• Pop. density is 26.6 people per sq.
km.
• Third most populous country in
the world.
• Pop. density is relatively low
compared to many other
developed countries due to its size
and its colonial history. E.g pop.
density of the US is one twelfth of
the Netherlands.
USA population density
USA’s Population Density
• 82% of the pop. reside in cities
and suburbs. This leaves vast
expanses of the country
uninhabited.
• Deciduous vegetation and
grasslands ( in the Appalachian
Mtns ) prevail in the east,
transitioning to prairies, boreal
forests and the Rockies in the
west, and deserts in the
southwest ( Great Basin ).
• In the northeast, the coasts of the
Great Lakes and Atlantic seaboard
host much of the country’s pop.
Appalachian Mountains
USA Population Density
• New Jersey is the most densely
populated state.
• Alaska is the most sparsely
populated state where tundra and
arctic conditions prevail in the
north.
Alaska
Brazil’s Population Density
• Pop. density is 18 people per sq.
km.
• Fifth largest country in the world
and has one of the highest pop.
• Pop. density is relatively low
since much of the country is
covered in rainforest (Amazon).
• The Amazon Basin occupies
more than 60% of the entire
country and receives more than
80 inches of rain a year in some
areas making the area wet,
humid, infertile and inhabitable.
Brazil Population Density
Brazil’s Population Density
• The basin contains the most
extensive river system in the
world.
• 20% of Brazil is covered with a
woodland savanna ( ‘cerrado’).
Here the climate is hot, semi
humid with rainy summers and
dry winters.
• The south-east contains the
cities of Sao Paulo and Rio de
Janeiro on the Atlantic coast
where the pop. density is so high
that air and water pollution are a
major concern.
Image of Rio de Janeiro
Canada’s Population Density
• Pop. density is 2.9 people per sq.
km.
• Second biggest country in world.
• Physical geography of Canada is a
factor in its low pop. density.
• Coniferous forests prevail
throughout the country, ice is
prominent in northerly Arctic
regions and through the Rocky
Mtns. in the west.
Canada Population Density
Canada’s Population Density
• Largest region is the Canadian
Shield ( consists of some of the
oldest rock in the world ).
Southern part is covered with
boreal forests ( coniferous ) while
the northern parts are tundra
because it is too far north for
trees.
• Because of the harsh weather and
geography in the north, nearly
90% of Canadians live within 99
miles of the US border.
• Three largest urban areas in
Canada are Toronto, Vancouver
and Montréal.
Toronto
Conclusion
• China, Russia, USA, Brazil and Canada have relatively low
pop. densities due to their location and geography.
• China has the highest pop. density from the list above,
not only because of its geography but because of its past
political policies. Even though the Communist
government has forced people to migrate from the
densely populated east to the sparsely populated west,
the distribution is still uneven.
• Settlers are attracted to an area by mild climate, flat
fertile land, natural resources and good job
opportunities.
• Settlers are repelled from an area by extreme climates,
mountainous areas, dense vegetation and limited job
opportunities.

Population density

  • 2. Introduction • Population density is an often reported and commonly compared statistic for places around the world. • It is commonly represented as people per sq. km. ( or sq. mile ). • Total area population / land area in sq. km. ( or sq. mile) • Density within a country can vary dramatically depending on geographical and economic factors so pop. density is only a raw gauge to measure a population’s disbursement across the land. • About 90% of the earth’s people live on 10% of the land.
  • 3. Largest Countries Country Population ( 000 people ) Area ( 000 km2⃣) Population density ( people / km2⃣) Brazil 153,725 8,512 18 Canada 29,248 9,971 2.9 China 1,208,841 9,561 126.4 Russia 147,997 17,075 8.7 USA 260,650 9,809 26.6 These are the five largest countries and economies in the world. Their population densities vary greatly.
  • 4. China’s Population Density • Pop. density is 126.4 people per sq. km. • Most populated country in the world. • 4th biggest country in the world. • The western and northern parts of China have a few million people, while the eastern half has about 1.3 billion, the vast majority living in major cities. China’s Population Density
  • 5. China’s Population Density • Population is most sparse in the mountainous, desert and grassland regions of the northwest and southwest. • The south-west is home to the harsh Tibetan Plateau which leads to the Himalaya Mtns. The high altitudes and harsh cold temperatures in the winter, make this one of the least populous areas in the world. Himalaya Mountains
  • 6. China’s Population Density • Flowing out of the Tibetan Plateau are two of China’s longest rivers, the Yangtze and the Yellow River. They cut across China as they continue towards the east coast through the more densely populated areas. • About 20% of China’s land is desert. The largest deserts are the Gobi and the Taklamakan Desert in the north-west. These areas are sparsely populated due to their arid environment and harsh winter climate. Gobi Desert
  • 7. Russia’s Population Density • Pop. density is 8.7 people per sq. km. making it one of the most sparsely populated countries in the world. • World’s largest country and has a very diverse geography. • Forests cover some 40% of the entire Russian land mass. • Many mountain areas e.g the Ural Mtns, the Caucasus Mtns and the Altai Mtns in the south. Russia’s Population Density
  • 8. Russia’s Population Density • Siberia- scarsely populated area covered by coniferous forests, swamps and tundra in the north- extreme climate • Pop. most dense in the western part of the country ( North European Plain ), centering around Moscow and St. Petersburg. • 74% of pop. is urban.

  • 9. USA’s Population Density • Pop. density is 26.6 people per sq. km. • Third most populous country in the world. • Pop. density is relatively low compared to many other developed countries due to its size and its colonial history. E.g pop. density of the US is one twelfth of the Netherlands. USA population density
  • 10. USA’s Population Density • 82% of the pop. reside in cities and suburbs. This leaves vast expanses of the country uninhabited. • Deciduous vegetation and grasslands ( in the Appalachian Mtns ) prevail in the east, transitioning to prairies, boreal forests and the Rockies in the west, and deserts in the southwest ( Great Basin ). • In the northeast, the coasts of the Great Lakes and Atlantic seaboard host much of the country’s pop. Appalachian Mountains
  • 11. USA Population Density • New Jersey is the most densely populated state. • Alaska is the most sparsely populated state where tundra and arctic conditions prevail in the north. Alaska
  • 12. Brazil’s Population Density • Pop. density is 18 people per sq. km. • Fifth largest country in the world and has one of the highest pop. • Pop. density is relatively low since much of the country is covered in rainforest (Amazon). • The Amazon Basin occupies more than 60% of the entire country and receives more than 80 inches of rain a year in some areas making the area wet, humid, infertile and inhabitable. Brazil Population Density
  • 13. Brazil’s Population Density • The basin contains the most extensive river system in the world. • 20% of Brazil is covered with a woodland savanna ( ‘cerrado’). Here the climate is hot, semi humid with rainy summers and dry winters. • The south-east contains the cities of Sao Paulo and Rio de Janeiro on the Atlantic coast where the pop. density is so high that air and water pollution are a major concern.

  • 14. Canada’s Population Density • Pop. density is 2.9 people per sq. km. • Second biggest country in world. • Physical geography of Canada is a factor in its low pop. density. • Coniferous forests prevail throughout the country, ice is prominent in northerly Arctic regions and through the Rocky Mtns. in the west. Canada Population Density
  • 15. Canada’s Population Density • Largest region is the Canadian Shield ( consists of some of the oldest rock in the world ). Southern part is covered with boreal forests ( coniferous ) while the northern parts are tundra because it is too far north for trees. • Because of the harsh weather and geography in the north, nearly 90% of Canadians live within 99 miles of the US border. • Three largest urban areas in Canada are Toronto, Vancouver and Montréal. Toronto
  • 16. Conclusion • China, Russia, USA, Brazil and Canada have relatively low pop. densities due to their location and geography. • China has the highest pop. density from the list above, not only because of its geography but because of its past political policies. Even though the Communist government has forced people to migrate from the densely populated east to the sparsely populated west, the distribution is still uneven. • Settlers are attracted to an area by mild climate, flat fertile land, natural resources and good job opportunities. • Settlers are repelled from an area by extreme climates, mountainous areas, dense vegetation and limited job opportunities.
