3 .A country’s birth rate is the number of births per year per 1,000 people in the country, and
a country’s death rate is the number of deaths per year per 1,000 people. Immigration

emigration rates in four countries and lines 1-4 in Figure 1 model the population for the
four countries shown over time.
