Name
the most populous continent. ______________
Which
continent has the highest rate of population growth? __________ lowest?
__________
Which
countries (name 2 or 3) have the highest rate of population growth.
___________________________
Which
countries (name 2 or 3 ) have populations that are no longer growing?
________________________
In
what year is the world population predicted to be twice as large as today
?______
In
what year will the population of North America be twice as large? ______
Rates
are often used to tell how frequently a population or demographic event is
occurring. List the types of information expressed as a rate in the
population data sheet.
The
crude death rate is the annual number of deaths per 1000 population.
Which country has the highest CDR?__________
lowest? ___________
Infant
mortality measures the number of deaths each year to infants under one year
of age per 1000 live births.
Which country has the highest infant mortality rate and what is it?
____________ lowest?
_____________
The
total fertility rate (TFR) is the average number of children women would
have if they maintained the current level of fertility throughout their
reproductive years. Which
country(s) has the highest TFR and what is it? ____________ lowest? ___________
Which
country is the wealthiest in terms of per capita Gross National Product
(GNP)? ______________ Second
wealthiest?_______________
A
population grows because more people are moving in than out and/or because
there are more births than deaths. The
difference between births and deaths is expressed as a percentage called the
rate of natural increase. Which
region is growing the fastest through natural increase? _____________
Which most slowly? _________
Which
country adds more people to its population yearly, China or India (hint:
calculate by applying the rate of natural increase to the
population).
How
many people does the United States add annually to its population?
________ How many
would be added if the US population grew at the same rate as Kenya? ________
Select
four countries whose populations are growing at a 0.1 percent rate of
natural increase or less. Then,
choose four countries whose populations are growing at a 3.0 percent rate of
natural increase or more (note:
don't select any countries in the Middle East.
Why are Saudi Arabia and some of the oil-rich countries exceptions?).
Then, fill in the table with the following data for each country:
infant mortality rate (IMR), total fertility rate (TFR), % under age 15,
Life expectancy, % urban, GNP.
