I think the correct answers from the choices listed above are options A, D and E. Life expectancy, crude death rate and crude birth rate are used to calculate total population growth of an area. They are the ones directly related to the population in a location. Hope this answers the question. Have a nice day.

Answer 2

The correct answers are:

b. Migration;

Through the migration the people move in or out of the area. The numbers of people that have moved in and people that have moved out are very important when it comes to calculating the total population, especially if it is an area with migration rates.

d. Crude death rate;

The number of the people that have died in a particular time is important because it tells us how much has the population lost in numbers.

e. Crude birth rate;

The birth rates are very important because they show us the numbers of how much new members the population in the area had gained.
