Mathematical Model Predicts the Population Growth

I am attempting to develop a mathematical model that predicts the population growth in Greenland between the years 2015 and 2035 by using a recursion equation. To do this:

1.               Assume the data used from CIA Factbook is correct. Explanation: This assumption is reasonable because the CIA Factbook is a government generate source of facts which implies it is reliable. It is necessary because this data is the data used to determine parameters for the model.

2.               Assume Greenland does not enter a war, have a calamitous event such as a natural disaster or famine. This assumption is reasonable because Greenland has shown a trend in its population that does not include any steep rises or falls in population that would be associated with calamitous events. This assumption is necessary because the model I am capable of creating could not accommodate any extreme outliers in the data (ex: a single year with an extremely high death rate.).

In order to create an appropriate model for Greenland’s population, the variables
