Fertility Rate: The average number of
children a woman will have throughout
her childbearing years.
Doubling Time: The number of years
needed to double a population,
assuming a constant rate of natural

Infant Mortality Rate: - the number of deaths of
children under the age of 1, per thousand of
the general population.
Population Characteristics
Life Expectancy : The average number of years
an individual can be expected to live, given
current social, economic, and medical
conditions.
Population under the age of 15 - usually
shown as a percentage of the total population
of a country - dependency ages
Population over the age of 65 - usually shown
as a percentage of the population.

POPULATION & DEMOGRAPHIC
PYRAMIDS TRANSITION
Demographic Transition - Stage 1
Demographic Transition - the change
in population characteristics of a
country to reflect medical technology or
economic and social development.
Crude Birth Rate: High 40-50 / 1,000
Crude Death Rate: High 40-50 / 1,000
Natural Increase Rate: None 0 / 1,000
Today, no country in the world is in Stage 1.
Demographic Transition
Demographic Transition - Stage 2
As medical technology is introduced, a
population lives longer as the death rate
is lower from the rates of stage one.
Crude Birth Rate: High 40+ / 1,000
Crude Death Rate: Lower 15 / 1,000
Natural Increase Rate: Very High 25+/1,000
Дэлхийн хүн ам
Demographic Transition - Stage 3
As the wealth and education of a
country increases, social norms, and
use of contraception dictate the birth of
fewer children per woman.
Crude Birth Rate: Lower 20 / 1,000
Crude Death Rate: Low 10 / 1,000
Natural Increase Rate: Low 10 / 1000
Дэлхийн хүн ам
Demographic Transition - Stage 4
As the final stage in the transition of
population characteristics, the fourth
stage sees the population increase rate
again at 0. This stage reflects a highly
industrialized, educated society.
Crude Birth Rate: Low 10 / 1,000
Crude Death Rate: Low 10 / 1,000
Natural Increase Rate: None 0 / 1,000
