How do you calculate doubling time of a population?
How do you calculate doubling time of a population? To figure out how long it would take a population to double at a single rate of growth, we can use a simple formula known as the Rule of 70. Basically, you can find the doubling time (in years) by dividing 70 by the annual growth rate. How long will it take for a population growing at 1% to double twice? For example, if an economy grows at 1% per year, it will take 70 / 1 = 70 years for the size of that economy to double. If an economy...
