    Let's say there is 50 people. In 40 years the population then is 100.

    50/14 = 3.6 - - Since you can't exactly split a single person up, you'd have to round up to 4, and some years being 3. Since it is a rate however, 3.6 would be technically okay.

    Number wise, the rate is 3-4 people every year.

    Percentage wise, the rate is 7.2% growth rate every year.

    Simply take 3.6/50 = 0.072

    0.072 x 100 = 7.2%

    :D
