Answer

Answer:

B. 3 deaths, 6 births, 5 immigration, 7 emigration

Explanation:

Step1: Calculate population change in 2011

Population change in 2011 = Births + Immigration - Deaths - Emigration = $5 + 6-2 - 8=1$

Step2: Calculate population change in 2012

Population change in 2012 = Births + Immigration - Deaths - Emigration = $4 + 1-1 - 3=1$

Step3: Calculate population change for each option in 2013

Option A:

Population change = $7 + 2-4 - 6=-1$

Option B:

Population change = $6 + 5-3 - 7=1$

Option C:

Population change = $2 + 8-5 - 3=2$

Option D:

Population change = $5 + 3-1 - 7=0$ Since the population change in 2011 and 2012 was 1, option B with a population - change of 1 in 2013 will keep the population growth the same as the previous years.
