How do you determine a
populations growth rate?
How do you determine a
populations growth rate? Count
the number of people that were
born, died, emigrated and
immigrated and compare that to
the number of people which
existed the previous year.
Determine the population growth rate
if there were 20,000 people living on
Catalina in 2012 and in 2013 100
babies were born, 50 people died, 5
people immigrated to the island and 3
people emigrated from the island.
Determine the population growth rate
if there were 20,000 people living on
Catalina in 2012 and in 2013 100
babies were born, 50 people died, 5
people immigrated to the island and 3
people emigrated from the island.
1. 100 births+ 5immigrants – 50deaths 3emigres = an increase of 52 people
2. 52 people/20,000 people = 0.25% growth
rate 20,052 – 20,000 x 100 = 0.25%
20,000
If Catalina has a 0.25% growth
rate, how many years will it take
the population to double?
If Catalina has a 0.25% growth
rate, how many years will it take
the population to double?
Use the rule of 70:
70/0.25 = 280 YEARS
Define the following: Crude Birth
Rate, Crude Death Rate, the Total
Fertility Rate and Replacement Level
Fertility
CBR =
CDR =
TFR =
RLF =
Define the following: Crude Birth
Rate, Crude Death Rate, the Total
Fertility Rate and Replacement
Level Fertility
CBR = Number of births per 1000 people
CDR = Number of deaths per 1000 people
TFR = Average number of children each woman
will have
RLF = Number of children each couple must have
to prevent the population from declining. (2.1 in
U.S.)
Calculate the population growth
rate of the world if the CDR is 8
and the CBR is 20.
Calculate the population growth
rate of the world if the CDR is 8
and the CBR is 20.
World population growth rate = (CBR-CDR) divided by 10
Divide by 10 because CBR and CDR are per 1000 people.
(20-8) divided by 10 = 1.2 percent.
If the world’s human population is
growing at a 1.2% rate, how long
will it take for the world’s population
to double?
If the world’s human population is
growing at a 1.2% rate, how long
will it take for the world’s population
to double?
Use the Rule of 70 to calculate
doubling time.
70/1.2 = 58 years
Human population in billions
What type of growth is illustrated by the
graph of human population below?
Year
Human population in billions
What type of growth is illustrated by the
graph of human population below?
Exponential Growth
Year
Look at the age structures below and
determine which population is
growing the fastest and which is
declining the fastest.
Look at the age structures below and
determine which population is
growing the fastest and which is
declining the fastest. Nigeria is
growing the fastest and Bulgaria is
declining the fastest.

considered important.
Children are important sources of
income and take care of elders.

worlds population.
Urban Areas consume _______% of the
world’s resources.
Urban Areas = __50___% of the
worlds population.
Urban Areas consume __75_____% of the
world’s resources.
List the factors that make some
countries have a high infant
mortality rate
List the factors that make some countries have a
high infant mortality rate limited access to health
care, poor nutrition, non potable water, low GDP
per capita, proximity of pollutants
