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 ( the-world-factbook/ ) to obtain the following information for Haiti (2009 estimates). Note: The information is located under the tab titled “people.”: i. Population growth rate 1.838% ii. Crude birth rate (per 1,000 individuals) 29.1 per 1,000 iii. Crude death rate (per 1,000 individuals) 8.65 per 1,000 iv. Net migration rate (per 1,000 individuals) -2.07 per 1,000 v. Life expectancy at birth 1

60.78 years vi. Total fertility rate (TFR) 3.81 children per woman (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? 29.1-(8.65+2.07) = 18.38 per 1,000 or 1.838% With no migration, 29.1-8.65 = 20.45 per 1,000 or 2.045% (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? GRR = TFR*0.488 = 3.81*.488 = 1.859 Using 0.493 (the actual estimate for Haiti). Then: GRR = TFR*0.493 = 1.878 The GRR is about 1.94 lower than the TFR [e.g., about 50% lower] (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? NRR ~ GRR*survivorship to mean of childbearing years = 1.859*0.888
