A population grows with an annual growth rate of 16.3 % per year. (a) what is the monthly growth rate?

Annual growth rate of population is 16.3%

monthly growth rate = ?

Months in one year = 12

let x be the monthly growth of population.

16.3% = 0.163

1 + 0.163 = 1.163

Now, (1.163) ¹/¹² = 1.01266

for monthly growth percent

1.01266 - 1 = 0.01266 = 0.01266 x 100 = 1.266%≈ 1.3%
