Question

If a city of 10,000 experiences 200 births, 60 deaths, 10 immigrants and 30 emigrants in the course of a year, what is its net annual percentage growth rate? (by what percentage did the population change?)

Answer 1

10000 + 200 - 60 + 10 - 30

10000 + 210 - 90

10000 + 120

10120

10000x = 10120

x = 1.012

101.2%

Their population changed by 1.2%
