The resource booklet provides information on Brazil. Use the resource booklet and your own studies to answer the following.
Using data from Figure 5(a) in the resource booklet, calculate the natural increase rate for Brazil in 2015.
Identify one reason why the natural increase rate, calculated in part (a), is different from the actual growth rate of the population, which was 0.63% in 2015.
Markscheme
(natural increase = ) = 0.788%/ 0.79% / 0.8%;
7.88 per thousand.
Correct units (% or per thousand) are required to be credited the mark.

Examiners report
Many candidates struggled to calculate the natural increase rate (NIR) correctly. Some candidates failed to apply the correct units. There were a significant number of candidates that did not attempt either of the calculation questions in this paper.
Many candidates were unable to identify migration as a factor that affected NIR. Many responses incorrectly suggested that the NIR did not take into account the crude birth rate, death rate or indigenous tribes. Some candidates did not appear to make the connection that the question was asking why the actual NIR was lower than the calculated rate in Q5a.
