The rule of 70 is a widely used method to estimate how long it will take for a country to double its real GDP per capita. The rule states that to find the number of years it takes for an economy to double in size, one should divide the number 70 by the annual growth rate of the economy. For example, if an economy has a growth rate of 3%, then it will take about 23 years (70/3) for that economy to double in size. Therefore, the best choice for estimating the time it will take for a country to double its real GDP per capita is the rule of 70.
