Explanation:
Step1: Calculate population change
Let the initial population be $P$. The change in population $\Delta P$ is calculated by adding the number of births and immigrants and subtracting the number of deaths (from being hit and harvested). Births $b = 3$, deaths $d=2 + 1=3$, immigrants $i = 2$. So $\Delta P=b - d+i$.
Step2: Substitute values
$\Delta P=3-3 + 2=2$.
Answer:
The deer population has increased.

Brief Explanations:
Financial prosperity in a country often attracts people from other regions as they seek better - economic opportunities, higher living standards, and more job prospects. Conflict and war usually cause people to flee a country (emigration), and birth is related to the natural increase within a country's population, not immigration.
Answer:
financial prosperity
