Given a 2005 world population growth rate of 1.14% per year, how long would it take the world’s population to double? By what year would this doubling occur? (See Using Math in Environmental Issues, pages  6 – 8 for a review of doubling time.)

T = 70/r = 70/1.14 = 55.5 =61.4 years, so by 2066 the population would double.
