Respuesta :

Answer:

D

Explanation:

The crude growth rate, r, of a population is calculated by;

Option D; adding the crude birth rate to the crude death rate

  • In population demographics, there is what we call crude rate which is used to describe the demographics of an event for a particular population.

  • Now, there is crude birth rate (CBR) which is defined as the number of births per 1000 people in a given population over a specified period of time.

Also, there is what we call Crude death rate (CDR) which is defined as the number of deaths per 1000 people in a given population over a specified period of time.

Now, crude growth rate is gotten by adding those two namely CDR and CBR together.

Thus;

r = CBR + CDR
