Question

Assume a population of deer has a crude birth rate of 36 per 1,000/yr, a crude death rate of 20 per 1,000/yr, an immigration rate of 15 per 1,000/yr, and an emigration rate of 8 per 1,000/yr. What is the population growth rate

Answer 1

0.023%

Step-by-step explanation:

The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula

`N/t` where N is the total change in the population size, and t is time.

When immigration and emigration are factored in, we now have the formula;

`(CBR +I) - (CDR + I)/1000`

`= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\`
