In 2014, in one place with 80 inhabitants, 9 babies were born, 7 people died, 15 immigrants arrived, and 6 emigrants left.
What was the NATURAL GROWTH RATE? What was the REAL GROWTH RATE? What was the FINAL POPULATION?
Initial population 80 inhabitants Birth rate 9 Death rate 7
NATURAL GROWTH RATE 9-7=2 2 Immigrants 15 Emigrants 6 REAL GROWTH RATE 2+15=17-
6=11 11 FINAL POPULATION 80+11= 91
