Solution:

200 births and 10 immigrants will be added to the population. Total is 210.

60 deaths and 30 emigrants will be taken away from the population. Total here is 90.

Just a reminder that an emigrant is somebody who leaves their own country to lastingly settle into a different country.

Therefore, 210 people are added to the population, and 90 people are to be subtracted, for a net gain of 210 - 90 = 120 people.

What percentage is 120 of 10,000?

120/10,000 = 0.012 = 1.2% annual growth rate
