2. POPULATION PYRAMID
 A population pyramid is a graphical illustration that
shows the distribution of various age groups in a
population
 also called age‐sex pyramid

3. THREE GENERAL KINDS OF POPULATION
PYRAMIDS
 1. Stationary
 2. Expansive
 3. Constrictive

4. EXPANSIVE PYRAMID
 A steady upwards narrowing shows that
more people die at each higher age band
 This type of pyramid indicates a
population in which there is a:
 high birth rate
 high death rate
 short life expectancy
 This is the pattern of a economically developing
country

5. STATIONARY PYRAMID
 A population pyramid showing an unchanging
pattern of fertility and mortality
 It indicates slow population growth or stable
population.
 The stationary or near stationary population
pyramid displays somewhat equal share of juvenile
and adult age groups.

6. CONSTRICTIVE PYRAMID
 A population pyramid showing lower numbers
or percentages of younger people
 The country will have a graying population which
means that people are generally older
 It represents low fertility, low mortality, high life
expectancy and ageing of population.
 It is typically associated with very advanced
countries which have a high level of literacy, east
access to birth control measures and very good
health and medical facilities.
