Answer:. The growth rate is 0.3%
0.286% if a more accurate percentage is required.
Step-by-step explanation: Add Births and immigrants
100,000+30000= 130,000
Subtract deaths and emigrants
-70,000 -40,000
Net gain in population: 20,000
Divide 20000/7000000=0.002857142857
Round and change to percent:
0.286% or 0.3%
