map and the definitions. Stop
@ bottom of page 2
2) Vocab quiz Thursday – you will
turn in vocab cards before
quiz… FOLLOW THE FORMAT!
3) Current Event due Friday –
Human Geography
(population, economics,
politics/government, etc.)
POPULATION GEOGRAPHY
• SWBAT
– Make inferences about
country population and
development by analyzing
population pyramids.

Today world population is estimated to be
BILLION people – the most in human history!!
Population Density
Which continent has the largest population???
ASIA
What is a population pyramid?
• It is a diagram that gives information about
the proportion of males and females in
each age group.
• Also shows:
- proportion of young people (0 -14 )
- proportion of working people (15 – 59)
- proportion of elderly people (60+)
Importance of Population Pyramids
• Each pyramid tells a story about the past,
present & future of a country & its people.
• Policy Planning
~ future housing estates
~ future schools
~ future jobs
• Comparison with other countries
~ developed (US) vs developing (India)
How to read a population pyramid?
• Read the title e.g. country or city or
racial group
• Comment on general shape of the
pyramid
• Note the proportion of people in various
age groups
• Note the sex ratio
• Interpret the data
Population Pyramids are just 2 Bar Graphs turned back-to-back so
you can see population growth patterns.
One side shows MALES, the other side shows FEMALES
The population will be graphed in RAW NUMBERS
(like here)
 Population Pyramids in percentages do NOT show you how big/small the
population of a country is.
 Population Pyramids in raw numbers make you add up all the info from
both sides to get the total population.
The older
population is
on top –
The younger
population is
on the bottom
Population Pyramids should be labeled with the location
and the year
Population Pyramids can also show wars and pandemics
Shape of pyramids is controlled by
births, deaths, & migrations
What the Shapes Mean
Developing or
Less Developed
Country (LDC)
Newly
Industrialized
(NIC)
Developed or
More Developed
Country (MDC)
Triangular-shaped Pyramid
(Broad-based Pyramid)
What is the largest age group?
(YOUNG, OLD, WORKING)
WHY DO DEVELOPING COUNTRIES
NEED SO MANY CHILDREN???
Triangular Pyramid
Title: India, 2000
Shape: Broad Base - high birth rates
Narrow Top - small elderly pop
- high death rate
Proportion: - Large proportion of young people
- high dependency ratio
Beehive-shaped Pyramid
Beehive-shaped Pyramid
Title: Brazil, 2012
Shape: Rocket-shaped / Narrow Base
– Low Birth Rates, Slow pop growth
Proportion: Large proportion of working
population, 15-59 yr old
large group of economically active pop
Rectangular-shaped Pyramid
Rectangular Pyramid
Title: Netherlands, 2000
Shape: Rectangular-shaped - Zero Pop Growth
Narrow Base - Low Birth Rates
Proportion:- Life-expectancy is high e.g. 80+
- Low death rates

What is an Economic Indicator?
• An economic indicator is a statistic about the
economy. Just like sports stats tell us how an
athlete is performing, economic indicators
help us know how a country is doing
economically, though many people use them
to assess the health of a country as a whole.
LIFE EXPECTANCY/INFANT
MORTALITY RATE
• LE: The number of years on average a person from
that country could expect to live.
• IMR: Number of infant deaths per 1000 live births
Way to see how strong/weak a
country’s health care is.
GROSS DOMESTIC PRODUCT (GDP)
• Total value of all the goods (stuff) and services
(help) produced in a country over a year.
• Tells you whether a country’s economy is
going up or down.
PER CAPITA
GROSS DOMESTIC PRODUCT (GDP)
• Total value of all the goods
(stuff) and services (help)
produced by an average person
in a country over a year (NOT
how much they earn).
• This tells you if a country has
high-skilled or low-skilled
workers.
USA GDP $16.8 Trillion Dollars
USA GDP Per Capita $53,000
LITERACY RATES
• The percentage of people
who can read and write in
a country
• Tells you how well
educated a country is and
if they have high-skilled
workers or not
*95% and lower and considered to
be low literacy rates
Wednesday
• Get out hand out from yesterday (Population
mini unit)
• Get out Pre-Globalization homework from last
night
• Get out World Picture from Tuesday
• Sub, vocab, CE card, Open House
The Human Development Index
• The HDI is an indicator of level of development for
each country. It is a calculation of different
economic indicators that is always a number
between 0-1. It tells us if a country is Developing,
Newly Industrialized, or Developed. The indicators
included in this index are:
WHAT IS THE KEY TO
AIDING ECONOMIC
DEVELOPMENT?????
– 1) Life Expectancy
– 2) Infant Mortality
– 3) Literacy Rates
– 4) GDP Per Capita
Infrastructure
the fundamental structures and systems serving a country,
city, or area:: transportation and communication systems,
power plants, and schools
Putting it all together
• The shape of a Population Pyramid will tell you the general level of
development for a country. With the level of development you can then
assume a HDI number range as well as the life expectancy, infant
mortality rates, GDP per capita and literacy rates of a nation.
