According to the 'Rule of 70,' how quickly will a population double if it has a constant growth rate of 10% per time period?

Answer

Every 7 time periods

The 'Rule of 70' estimates doubling time by dividing 70 by the percentage growth rate; therefore, a 10% rate means the population doubles approximately every 7 time periods ($70/10=7$).
