Day 1
Demography Activity
• Target people, were you able to determine
what your label said? How?
• Marketers, how did you go about selecting
your target people?
• Who was not targeted? Why?
• Observers, please comment on what you
saw during the activity, from both the
target people .
So, what kind of information are
companies looking for?
Social Trends
• In social science these are not fads,
fashions or the latest things.
• These are “large scale changes in a
society.”
– Anthropologists study how they affect ______
– Sociologists study their impact on _____,
______ and _________
– Psychologists study how they affect _______
Demography
• “the study of changes affecting human
population”
• “is concerned with the overall population,
the immediate phenomena that alter it as a
whole (births, deaths, migrations), or
changes in its composition (sex, age,
marital status, language, religion,
education, income, etc.)”

Uses of Demography
By
For (e.g.)
Gov’t
Planning for future
services such as
hospitals
Businesses
Knowing customers’
buying habits;
planning where to
locate a new store
Organizations (such
as charities)
Knowing how many
immigrants will come
to a city in the future
School boards
Where will schools
have to be built
and/or closed
Population Change
• Natural balance of births, deaths, movement of
people (immigration & emigration)
– What would be the best kind of balance for a country
such as Canada? What kind of situation are we in
now?
• Define from page 146:
– Natural increase
– Natural decrease
– Net migration
• Therefore, population change = natural inc/dec +
net migration
Population Pyramid (PP)
• A quick way to determine population
characteristics and some change over time
• A type of graph that demonstrates population
patterns by age and sex
– Cohorts = age groups or categories
– Male and female % of total population shown
– Describe the shape of the base, middle and tip for
1961 and 2006?
• What does a PP not show (or tell you)?

Group Task
•
Using the 2006 Population Pyramid (blue with
generation names), identify:
1. What we mean by the base of the PP and what it
was like in 2006 (narrow, medium, wide)
2. What we mean by the top of the PP and what it was
like in 2006 (narrow, medium, wide)
3. What we mean by the middle of the PP and what it
was like in 2006 (narrow, medium, wide)
4. Which generation do you think has had the most
impact on Canada as it has gone through its life
stages (children, teenagers, adults, seniors)? Why?
Social Impact of Baby Boom
• What happens when
a country’s population
rises a lot during a
short period?
Year
Canada’s
Population
*By 1966 half of the population
was under 24 years old. Now
that group makes up 25%.
What is the
impact of a large
generation as it
gets older?
•
1946
12 million
1966
20 million*
