2 Demographic Facts
On Tuesday, January 12
th
of this year, a devastating 7.0 magnitude earthquake struck
Haiti causing widespread damage and untold loss of human life.
To learn more about
Haiti as well as to familiarize yourself with sources of demographic data and facilitate a
better understanding of some of the concepts discussed in lecture, this question asks
you to use online sources to locate some basic demographic information for Haiti and to
make a couple of key calculations.
(A) Please use the CIA World Fact Book
(
https://www.cia.gov/library/publications/theworldfactbook/
) to obtain the
following information for Haiti (2009 estimates).
Note: The information is located
under the tab titled “people.”:
i.
Population growth rate
ii.
Crude birth rate (per 1,000 individuals)
iii.
Crude death rate (per 1,000 individuals)
iv.
Net migration rate (per 1,000 individuals)
v.
Life expectancy at birth
vi.
Total fertility rate (TFR)
(B) Verify that the population growth rate can be obtained by subtracting the
crude death rate and the net migration rate from the crude birth rate.
What
would the population growth rate have been if there had been no migration in
this year?
(C) Using the standard estimate for the fraction of births that are female
presented in lecture, calculate the Gross Reproduction Rate (GRR) for Haiti.
How much lower is the GRR than the TFR?

(D) Assume that 88.8% of women survive until the age of 30 which we will
assume is the mean age of childbearing and continue to use the standard
estimate of births that are female.
What is the Net Reproduction Ratio (NRR)
for Haiti?
(E) Continuing to assume that 88.8% of women survive through their mean
age of childbearing, estimate the Total Fertility Rate that Haiti would need in
order to achieve a net reproduction ratio (NRR) of 1, which corresponds to
zero population growth.
Assuming this target TFR was met this year, would
the population growth rate become equal to zero immediately?
Briefly explain
your answer.
(F) Referring again to the CIA World Fact Book, what is the adult prevalence
