Question 2.
What is the formula for calculating growth rate?
Show hintHide hint
Remember to include both immigration and emigration.
3Question 3.
What is the formula used to calculate growth rate?
- r = births - deaths
- r = (births + immigration) - (deaths + emigration)
- r = births + (deaths - immigration)
