Finding FUTURE Population from Growth Rate: (initial population ) X (growth rate ) years = Final Population. NOTE: a growth rate of 3% is expressed as 1.03; a growth rate of 0.25% is 1.0025. for example: (468,843 people ) X (1.03 ) 10 years = 630,085 people. Population Problems – SHOW ALL WORK!!

Using the formulas in your text, you can determine the world’s annual growth rate and doubling time based on the growth during 1991. Percent annual increase = (birth rate - death rate) = 27 - 9 = 1.8% 10 10 Doubling time = 70 = 70 = 39 years

Intuitively, rate of increase of population will be sensitive to both new reproductive rate Ro and generation time - faster generation time and higher reproductive rate, more rapidly the population grows. Contrast . r - instantaneous rate of population growth. lamda - finite rate on population increase. r ranges from - infinity to + infinity

Doubling Time - When a population grows exponentially, the time it takes for the population to double, called “doubling time,” can be approximately calculated using the “Rule of 70,” which in formula form looks like this: Doubling Time = 70/growth rate . where doubling time is in years, and growth rate is expressed as a percentage.
